In October 2008, a phone landed on shelves with a sliding keyboard, a clunky chin design, and no headphone jack. Reviewers were lukewarm. But inside that ugly device — the HTC Dream, sold in the US as the T-Mobile G1 — lived a piece of software that would quietly take over the world. That software was Android 1.0. Eighteen years later, it runs on 3.9 billion active devices across every continent, powers your smartwatch, your car's dashboard, and your TV, and holds over 72% of the entire global mobile OS market (StatCounter, January 2026). This is the complete story of what Android OS is, how it got here, and why it matters to you right now.
Whatever you do — AI can make it smarter. Begin Here
TL;DR
Android is an open-source mobile operating system built on the Linux kernel, developed primarily by Google.
It powers approximately 3.9 billion active devices worldwide as of early 2026, holding ~72% of the global mobile OS market (StatCounter, 2026).
Google acquired Android Inc. for $50 million in July 2005; the first Android phone launched in October 2008.
The latest stable version is Android 16 (released June 10, 2025), with Android 17 expected in Q2 2026.
Android dominates emerging markets — India leads with 95.21% Android share — but trails iOS in the US (Android ~40% vs iOS ~60%).
Android's open-source core (AOSP) allows any manufacturer to use it for free, which is the main driver of its scale.
What Is Android OS?
Android OS (Android Operating System) is an open-source mobile software platform built on a modified Linux kernel. Developed by Google and the Open Handset Alliance, it powers smartphones, tablets, TVs, smartwatches, and cars. As of early 2026, it holds over 72% of the global mobile market and runs on approximately 3.9 billion active devices worldwide.

Background & History
Where Android Came From
Android Inc. was founded in October 2003 in Palo Alto, California, by four engineers: Andy Rubin, Rich Miner, Nick Sears, and Chris White. The company's original goal was not smartphones at all. Rubin wanted to build a smarter operating system for digital cameras — one connected to cloud storage and aware of user preferences. By 2004, the digital camera market was already declining. The founders quickly pivoted to mobile phone software. (Android Authority, 2023)
The company ran out of money. At one point, investor and friend Steve Perlman physically withdrew $10,000 cash from a bank and handed it directly to Rubin to keep the company alive. That infusion bought enough time for a far bigger deal to arrive. (Android Authority, 2023)
In January 2005, Google reached out to the Android co-founders. Larry Page and Sergey Brin saw two presentations of Android's prototype mobile OS and immediately moved to acquire the company. On July 11, 2005, Google purchased Android Inc. for approximately $50 million — its most valuable acquisition per dollar in history, according to Google's then-VP of corporate development David Lawee. Rubin, Miner, and White joined Google as part of the deal. (Android Authority, 2023)
Google spent the next three years developing Android into a full mobile platform built on the Linux kernel — the same foundational code that powers most of the world's servers and supercomputers. The choice of Linux was deliberate: it was free, robust, and could be offered to phone makers at no cost.
The Open Handset Alliance
On November 5, 2007, Google unveiled the Open Handset Alliance (OHA) — a consortium of 34 technology companies committed to open standards for mobile devices. Members included HTC, Motorola, Samsung, Qualcomm, T-Mobile, and Texas Instruments. The OHA's stated goal was to create "the first truly open and comprehensive platform for mobile devices." (Wikipedia: Android, 2026)
The iPhone had already launched that June, and the smartphone race was officially on.
The First Android Phone
On September 23, 2008, HTC and Google announced the HTC Dream, sold in the United States as the T-Mobile G1. It went on sale on October 22, 2008, for $179 with a two-year contract. The phone had a 3.2-inch touchscreen, a slide-out QWERTY keyboard, 192 MB of RAM, and 256 MB of internal storage. It had no virtual keyboard and no headphone jack — both glaring omissions. Reviews were mixed. (Wikipedia: HTC Dream, 2026)
But the software inside was remarkable. Android 1.0 came pre-loaded with Google Maps, YouTube, Gmail, and Google Search. It had a notification drawer — a feature Apple wouldn't match for three more years. It supported third-party apps, customizable home screens, and true multitasking. The foundation for everything that followed was already there.
How Android Works: Architecture Explained Simply
Android is not a single program. It is a layered software stack — think of it as a multi-floor building where each floor handles a different job.
Layer 1 — Linux Kernel (the basement): This is the engine room. The Linux kernel manages hardware communication: it controls the processor, memory, battery, camera, Wi-Fi, and every other chip in your phone. Android uses a modified version of the Linux kernel. As of Android 16 (released June 10, 2025), the platform is based on Linux kernel version 6.12. (Wikipedia: Android 16, 2026)
Layer 2 — Hardware Abstraction Layer (HAL): The HAL acts as a translator. Different phones use different camera chips or GPS modules. The HAL standardizes how Android talks to all of them, so app developers don't need to write separate code for every device.
Layer 3 — Android Runtime (ART): When you open an app, ART runs it. ART replaced the older Dalvik virtual machine back in Android 5.0 (2014). It compiles app code ahead of time, which means apps launch faster and run more efficiently.
Layer 4 — Native Libraries: These are pre-built code blocks for common tasks — playing video (libc), drawing graphics (OpenGL ES), handling databases (SQLite), and displaying web content (WebKit/Blink). Every app on your phone leans on these libraries constantly.
Layer 5 — Application Framework: This is what app developers interact with directly. It provides ready-made building blocks for creating UI elements, accessing location, managing notifications, and handling background services. It's why a developer in Lagos and a developer in Seoul can build apps that both work on a Samsung in Brazil.
Layer 6 — Applications: Everything you see and touch — Chrome, WhatsApp, Gmail, TikTok, the Settings menu. This is the layer users experience.
AOSP vs. Google Android
The Android Open Source Project (AOSP) is the public, free version of Android. Any manufacturer can take it and use it for free. However, most consumer Android phones ship with Google Mobile Services (GMS) — Google's proprietary layer on top of AOSP that includes the Google Play Store, Google Maps, Chrome, Gmail, and YouTube. GMS is not free; manufacturers must license it from Google and meet certain requirements. This is why Huawei — cut off from GMS licensing by US export restrictions — had to build its own app ecosystem. (Wikipedia: Android, 2026)
Android Versions: From 1.0 to Android 16
Google has followed a consistent pattern of annual major releases since 2009. Until Android 9 (2018), each version was named after a dessert in alphabetical order — Cupcake, Donut, Eclair, Froyo, Gingerbread, and so on. From Android 10 onward, Google switched to plain numbers for simplicity and global accessibility (some desserts don't translate well internationally).
Version | Codename | Year | Key Feature |
Android 1.0 | (none) | 2008 | Google apps, Android Market, notifications |
Android 1.5 | Cupcake | 2009 | On-screen keyboard, video recording |
Android 1.6 | Donut | 2009 | CDMA support, multiple screen sizes |
Android 2.0 | Eclair | 2009 | Google Maps Navigation, multi-account email |
Android 2.3 | Gingerbread | 2010 | NFC support, improved gaming |
Android 3.0 | Honeycomb | 2011 | Tablet-only redesign |
Android 4.0 | Ice Cream Sandwich | 2011 | Unified phone/tablet UI, Face Unlock |
Android 4.1–4.3 | Jelly Bean | 2012 | Google Now, smoother UI ("Project Butter") |
Android 4.4 | KitKat | 2013 | Optimized for low-RAM phones |
Android 5.0 | Lollipop | 2014 | Material Design, ART runtime |
Android 6.0 | Marshmallow | 2015 | Granular app permissions, Doze battery mode |
Android 7.0 | Nougat | 2016 | Multi-window, improved notifications |
Android 8.0 | Oreo | 2017 | Picture-in-picture, autofill |
Android 9.0 | Pie | 2018 | Gesture navigation, Digital Wellbeing |
Android 10 | Q | 2019 | Dark mode, scoped storage |
Android 11 | R | 2020 | Conversation notifications, one-time permissions |
Android 12 | S | 2021 | Material You theming |
Android 13 | T | 2022 | Per-app language settings |
Android 14 | U | 2023 | Photo picker, health connect |
Android 15 | V | 2024 | Satellite connectivity, theft detection |
Android 16 | Baklava | 2025 | Desktop windowing, Live Updates, Material 3 Expressive |

Android 16: What's New (Released June 10, 2025)
Android 16 (API level 36, codename "Baklava") was released on June 10, 2025 — several months earlier than usual, as Google shifted its major release cycle to Q2. This was intentional: earlier releases allow more device manufacturers to ship new hardware with the latest Android out of the box. (Android Developers Blog, January 2025)
Key features include:
Desktop Windowing: Tablets and foldable phones now support floating, resizable app windows — similar to how a laptop manages multiple programs. This feature turns large-screen Android devices into near-desktop experiences for productivity. (Wikipedia: Android 16, 2026)
Live Updates: A new notification type that shows real-time progress for ongoing activities — your Uber approaching, your food delivery status, your navigation progress — without cluttering the notification shade. (Android 16 official feature page, android.com, June 2025)
Material 3 Expressive: A major visual overhaul with increased animation, bolder colors, and blur effects. It began deploying to Pixel 6 and newer devices in September 2025. (Wikipedia: Android 16, 2026)
Linux Terminal: Android 16 expanded the ability to run full Linux applications within a virtual machine on supported devices using the Android Virtualization Framework. This creates a Debian-based environment for developers and power users. (Wikipedia: Android 16, 2026)
Notification Cooldown: When an app sends a burst of alerts, Android 16 gradually lowers the notification volume for up to one minute instead of blasting every alert at full volume. (Android Authority, December 2025)
Security — Advanced Protection Mode: A hardened security mode for high-risk users (journalists, activists, executives) that locks down data access, restricts sideloading, and adds extra authentication layers.
Samsung was the first manufacturer after Google to roll out Android 16, starting with the Galaxy S25 series (running One UI 8) in late 2025. By January 2026, all eligible Pixel devices (Pixel 6 through Pixel 10) had received the update. Oppo, OnePlus, Motorola, and Vivo all rolled out their Android 16-based skins by early 2026. (91mobiles, February 2026)
Android Version Distribution in 2026
According to Google's distribution data collected through December 2025:
Android Version | Market Share (Dec 2025) |
Android 16 | 7.5% |
Android 15 | 19.3% |
Android 14 | 17.2% |
Android 13 | 13.9% |
Android 11 | 13.7% |
Android 10 | 7.8% |
Android 9 | 4.5% |
Others | 16.1% |
Source: Android Headlines, January 2026; TelemetryDeck, January 2026
The data illustrates a persistent challenge: Android fragmentation. Millions of devices still run Android 10 or older, meaning they miss years of security patches and new features.
Current Landscape: Android in Numbers (2026)
Android's dominance in 2026 is not marginal. It is structural.
Global market share: As of early 2026, Android holds 70.36% of the global mobile market share while iOS holds 29.25%, according to StatCounter. Together they represent over 99.6% of all mobile devices.
Active users: There are 3.9 billion Android OS users in the world as of 2026, with Android capturing 73.9% of the mobile OS market.
Smartphone sales: Android controls 79% of global smartphone sales in Q3 2025.
All-device OS share: As of December 2025, Android, which uses the Linux kernel, is the world's most popular operating system with 38.94% of the global market across all device types, followed by Windows with 29.99%.
Google Play Store: The Google Play Store currently hosts 2.06 million apps, with Instagram as the most downloaded.
Leading manufacturer: Samsung leads Android vendors with 19.7% of total smartphone market share in Q2 2025, shipping 58 million units. Within the Android ecosystem specifically, Samsung controls 30.8% of vendor market share, followed by Xiaomi at 15.9%.
US market: As of 2026, iOS holds 59.8% of the US mobile market compared to Android's 40%.
App revenue: In 2025, total global consumer spending on mobile apps and games reached $155.8 billion, up 21.6% year-over-year. iOS accounted for approximately 70% of that spending — a key asymmetry, since Android has far more users but iOS users spend significantly more per person.
Metric | Value | Source | Date |
Global mobile OS share | 70.36%–72.77% | StatCounter / CommandLinux | Early 2026 |
Active Android users | 3.9 billion | DemandSage | 2026 |
Google Play Store apps | 2.06 million | DemandSage | 2026 |

US Android share | ~40% | StatCounter | Early 2026 |
Global smartphone shipments | 1.25 billion units | IDC | 2025 |
Key Drivers: Why Android Dominates
1. Open Source = No Licensing Fee
Any manufacturer can download AOSP, adapt it, and ship it on a device without paying Google. This is why you can find Android phones for $40 in rural India and $1,500 foldables in Seoul. The cost barrier to entry is zero. No other mobile OS offers this.
2. Fragmented Hardware Market Benefits Android
The smartphone market includes hundreds of manufacturers at every price point. Apple only makes iPhones. Android, by contrast, powers devices from Samsung, Xiaomi, Oppo, Vivo, Transsion, Motorola, OnePlus, and dozens more. Chinese manufacturers collectively account for over 42% of Android device shipments globally.
3. Emerging Market Penetration
Price-sensitive markets — where most of the world's new smartphone users live — overwhelmingly choose Android. India leads in Android market share with 95.21%, followed by Indonesia at 86.8% and Brazil at 81.45%. These markets are adding hundreds of millions of new users annually.
4. Google's Ecosystem Lock-In
Gmail, Google Maps, Chrome, YouTube, Google Drive, Google Photos — Android makes all of these the default experience. Switching away from Android means leaving behind saved preferences, app purchases, and years of data stored in Google's ecosystem.
5. Customization and Developer Freedom
Android allows sideloading (installing apps from outside the Play Store), custom launchers, third-party keyboards, and deep system-level customization. This openness attracts both power users and developers who want more control than iOS allows.
Android vs iOS: A Direct Comparison
Feature | Android | iOS |
Global market share (2026) | ~72% | ~28% |
US market share (2026) | ~40% | ~60% |
App store size | ~2.06M apps | ~2.1–2.2M apps |
Cost of entry | Free (AOSP); budget phones from ~$40 | $599–$1,599 (iPhone only) |
Customization | Extensive — launchers, sideloading, widgets | Limited, improving gradually |
Update delivery | Fragmented; varies by manufacturer | Unified; all supported devices updated simultaneously |
App revenue share | ~30% of $155.8B (2025) | ~70% of $155.8B (2025) |
Security updates | Varies by OEM; Pixel receives fastest | Consistent, usually 5–6 years |
Hardware variety | Hundreds of devices, all price points | One product line |
AI integration | Google Gemini, on-device AI expanding | Apple Intelligence, on-device AI |
Tablets | 48% global tablet share | 52% (iPadOS) |
Sources: StatCounter, 2026; MobiLoud, 2026; Wikipedia, December 2025
Note: App store size comparisons have shifted significantly. Google conducted a major cleanup effort in 2024, removing millions of low-quality apps from the Play Store. As MobiLoud (2026) reports, both stores now sit at roughly the same size — around 2.1–2.2 million apps — a notable change from years when Google Play had roughly twice as many apps as the Apple App Store.
Case Studies: Android's Real-World Impact
Case Study 1: Samsung's Android Dominance
Samsung became the world's top smartphone maker not by building its own OS, but by mastering Android. In 2010, Samsung launched the original Galaxy S — a direct rival to the iPhone 3GS, running Android 2.1. The device sold 24 million units in its first year and established the Galaxy line as a global brand.
By Q2 2025, Samsung shipped 58 million devices in a single quarter and held 30.8% of the Android vendor market share, according to IDC data cited by CommandLinux (December 2025). Samsung's layered strategy — building flagships (Galaxy S25 series), foldables (Galaxy Z Fold 7), and budget devices (Galaxy A series) — lets it capture every price tier simultaneously. Its early rollout of Android 16 as One UI 8, beginning with the Galaxy S25 series in late 2025, demonstrates how Samsung has become Google's most important hardware partner. (91mobiles, February 2026)
Case Study 2: India's Android Revolution
India is the most dramatic example of Android's global expansion. The country now has 95.21% Android market share — the highest of any major nation — and is on track for 1 billion smartphone users. India expects 1 billion smartphone users by 2026, with 80% using 5G-enabled devices.
This transformation was driven by two forces: extremely affordable Android hardware (Xiaomi's Redmi series consistently sells for under $150) and telecom revolution. In 2016, Reliance Jio launched 4G data at near-zero cost, connecting hundreds of millions of Indians to the internet for the first time — almost all of them on Android devices. The consequences were enormous. Digital payments, e-commerce, and streaming services built entirely around Android exploded in scale. Google's own Payments India product (Google Pay), Maps, and Search became infrastructure-level services in a country of 1.4 billion people. (CommandLinux, December 2025)
Case Study 3: Huawei's Android Separation — and HarmonyOS
In May 2019, the US Department of Commerce added Huawei to the Entity List, restricting its access to US technology — including Google Mobile Services. This meant new Huawei phones could no longer ship with the Google Play Store, Gmail, or YouTube. For a company that had been the world's second-largest smartphone maker, this was an existential crisis.
Huawei's response was to build its own OS: HarmonyOS NEXT. In November 2024, sales of the Huawei Mate 70 began with HarmonyOS NEXT installed — the first Huawei flagship to run no Android code at all. Since 2025, all new Huawei devices have exclusively been sold with the HarmonyOS NEXT operating system, creating a third player on the market for smartphone operating systems. In the first quarter of 2025, Huawei overtook Xiaomi to become the best-selling smartphone brand in China, with a 19% market share.
This is the only credible current threat to Android's dominance — and it is, so far, confined to China. HarmonyOS NEXT does not run Android apps natively. Its success in China is a sign that a well-funded government-backed alternative can unseat Android in a single large market. Outside China, HarmonyOS has negligible share.
Regional Variations: Android Around the World
Android's market position is not uniform. Geography matters enormously.
India: 95.21% Android market share. Xiaomi's Redmi and Samsung's Galaxy A series dominate, driven by aggressive pricing and strong 4G/5G network infrastructure expansion.
Indonesia: 86.8% Android share. Strong Oppo, Vivo, and Xiaomi presence. Mid-range devices priced between $150–$300 are the sweet spot.
Brazil: 81.45% Android share. Samsung leads with its A-series; Motorola holds strong in Latin America with an 8% share gain in the region (SQ Magazine, 2025).
United States: Reversed market — iOS leads with 59.8%, Android at 40%. The iPhone's cultural dominance among younger demographics, the iMessage ecosystem lock-in, and higher average incomes sustain Apple's lead. (MobiLoud, 2026)
China: Unique because Google services are blocked. AOSP-based Chinese Android forks (MIUI, ColorOS, OriginOS, HarmonyOS) operate without Google Play. HarmonyOS NEXT is now challenging Android's share directly.
Europe: Mixed. Android leads in most of Eastern and Southern Europe; Apple holds stronger positions in France, Germany, and the UK.
Pros & Cons of Android
Pros
Hardware choice: You can buy an Android phone for $40 or $2,000. No other OS gives you this range.
Customization depth: Change your default browser, launcher, keyboard, and dialer. Sideload apps. Connect USB drives. Android allows modifications that iOS still does not.
Google integration: For people deep in Google's ecosystem — Gmail, Drive, Maps, Calendar — Android is the natural home. Everything syncs seamlessly.
Developer openness: Android's open-source core allows manufacturers, researchers, and hobbyists to modify it freely. It powers everything from restaurant kiosks to in-flight entertainment systems.
Foldable leadership: Samsung's Galaxy Z Fold series and other foldable Android devices are years ahead of anything in the iOS ecosystem for form factor innovation.
Cons
Fragmentation: The diversity of Android hardware means updates arrive inconsistently. A phone from a budget manufacturer may receive security patches 6–12 months late, or never. Android 10 still runs on 7.8% of all Android devices in early 2026. (Android Headlines, January 2026)
Revenue gap: Despite 3x more users than iOS, Android generates roughly 30% of global app revenue vs iOS's 70% (MobiLoud, 2026). Developers often prioritize iOS first.
Malware risk: The open nature of Android and the ability to sideload apps creates a larger attack surface. Google's Play Protect scans for malware, but threats on Android outpace iOS in volume.
Bloatware: Many manufacturers ship Android devices pre-loaded with unnecessary apps that cannot be uninstalled, consuming storage and running background processes.
Inconsistent update policy: Unlike Apple — which pushes the same iOS update to all supported devices on the same day — Android updates depend on each manufacturer's timeline. Some manufacturers abandon update support after just 2 years.
Myths vs Facts About Android
Myth: Android is less secure than iOS.
Fact: Android has closed the security gap significantly. Android 16 introduced Advanced Protection Mode, monthly security patches, and Play Protect AI scanning. The claim was truer in 2012; in 2026 it is an oversimplification. The risk on Android is higher primarily for users who sideload apps from unverified sources.
Myth: Android is slower than iOS because of fragmentation.
Fact: Flagship Android phones (Samsung Galaxy S25, Google Pixel 10) benchmark comparably with or faster than iPhones on many tasks. The perception of "Android lag" stems from low-end and mid-range devices — a category that iOS does not participate in.
Myth: More apps are available on Google Play than on the App Store.
Fact: This was true for years, but Google's 2024 app quality cleanup reversed it. As of 2026, both stores host approximately 2.1–2.2 million apps. (MobiLoud, 2026)
Myth: Android is 100% free and open source.
Fact: AOSP is free and open source. But the version of Android most consumers use — with Google Play, Gmail, Maps, and YouTube — includes proprietary Google Mobile Services (GMS) that manufacturers must license from Google. The "free" Android and the Android on your phone are not the same thing.
Myth: Clearing RAM improves Android performance.
Fact: Modern Android versions (Android 6+) manage RAM automatically. Manually killing background apps can actually slow down your phone because apps must fully reload from scratch the next time you open them.
Pitfalls & Risks of Using Android
Buying devices without update commitments: Many budget and mid-range Android phones receive only 1–2 years of OS updates. In 2026, Google Pixel phones receive 7 years of updates; Samsung flagship phones receive up to 7 years. Check the manufacturer's published update policy before buying.
Sideloading from unverified sources: Installing APK files from unknown websites bypasses the Play Store's security scanning. This is the primary vector for Android malware. Only sideload from sources you trust completely.
Outdated devices on banking apps: Banks and financial apps increasingly require minimum Android versions. A phone running Android 9 or 10 may lose access to critical apps as developers drop support.
Over-relying on free VPNs: Free VPN apps on Google Play have been repeatedly caught selling user data. If privacy is your concern, use a paid VPN from a verified provider.
Ignoring monthly security patches: Android releases monthly security bulletins. Ignoring update prompts for months at a time leaves your device exposed to known, patched vulnerabilities.
Future Outlook: What's Coming for Android
Android 17
Google is expected to release Android 17 as a stable build in June 2026, following the same Q2 release cadence established with Android 16. For Android 17, Google will continue on the path it set for itself with Android 16, with a major SDK release in Q2 2026 and a minor SDK release in Q4 2026. Google has also replaced its Developer Preview program with a new "Canary" release channel — a continuous stream of early builds rather than discrete preview milestones. (Android Authority, February 2026)
Confirmed Android 17 features include mandatory adaptive app layouts for large screens (no opt-out, unlike Android 16) and continued expansion of Material 3 Expressive design changes.
AI Integration at Scale
AI is becoming the defining battleground for Android differentiation. Google Gemini is embedded into Pixel devices and spreading to Samsung's Galaxy AI. AI integration in mid-range Android devices presents a growth opportunity, with manufacturers pushing intelligent features into more affordable price points. On-device AI — running models locally without a cloud connection — is expanding rapidly as chip capabilities grow.
5G and Emerging Markets
The 5G rollout continues driving replacement cycles, with Ericsson projecting 3.5 billion 5G subscriptions globally by 2026. India and Southeast Asia, both overwhelmingly Android markets, are leading 5G adoption in the developing world. This migration is expected to drive significant Android hardware upgrades through 2027.
Foldables and New Form Factors
Foldable phones are projected to grow 6% in both 2025 and 2026. While still a niche category (approximately 1–2% of total smartphone sales), foldables are a category where Android — led by Samsung, Oppo, and Honor — holds a near-monopoly. Apple has no foldable in the market as of early 2026.
HarmonyOS: A Regional Threat
Huawei's HarmonyOS NEXT represents the only significant structural threat to Android's market share. Its dominance in China — the world's largest smartphone market — demonstrates that a well-resourced alternative can displace Android in a specific geography. Whether HarmonyOS expands beyond China remains unclear, but its existence reduces Google's leverage in the Chinese market to near zero.
Component Cost Pressures
IDC projects global smartphone shipments will decline 0.9% in 2026, primarily affecting low-end Android devices. Memory component shortages are expected to increase average selling prices to $465. Budget Android's price advantage may narrow slightly, which could affect Android's strongest market position in cost-sensitive emerging economies.
FAQ
1. What is Android OS in simple words?
Android is the software that makes smartphones work. It controls everything your phone does — making calls, running apps, connecting to Wi-Fi, and displaying the screen. It was built by Google and runs on about 3.9 billion devices worldwide as of 2026.
2. Who invented Android?
Andy Rubin, Rich Miner, Nick Sears, and Chris White founded Android Inc. in 2003. Google acquired the company in July 2005 for approximately $50 million. Rubin led Android's development at Google until 2013. (Android Authority, 2023)
3. Is Android free to use?

11. What is Android fragmentation?
Fragmentation refers to the fact that different Android devices run different versions of Android at the same time. In early 2026, Android devices are spread across Android versions 9 through 16. This means developers must test apps across many versions, and some users miss security updates for years. (Android Headlines, January 2026)
12. Is Android safe and secure?
Android has strong security in 2026 — monthly patches, Play Protect malware scanning, Advanced Protection Mode, and on-device encryption. Risk increases significantly when users sideload apps from untrusted sources or ignore update prompts.
13. What are Android skins?
Android skins are manufacturer-specific versions of Android's user interface layered on top of the base OS. Samsung's One UI, Xiaomi's MIUI, Oppo's ColorOS, and OnePlus's OxygenOS are all Android skins. They add features and change the visual design, but the underlying OS is still Android.
14. Does Android support foldable phones?
Yes. Android 16 specifically added and enhanced multi-window, desktop windowing, and resizable app features designed for foldable phones and tablets. Samsung, Oppo, and Honor are the leading foldable Android manufacturers.
15. What will Android 17 include?
Android 17 is expected in June 2026. Confirmed changes include mandatory adaptive app layouts for large screens (no developer opt-out), continued Material 3 Expressive design rollout, and the new "Canary" continuous release channel for developers. (Android Authority, February 2026)
Key Takeaways
Android OS is an open-source mobile operating system built on Linux, developed by Google and the Open Handset Alliance, first commercially released in October 2008.
It powers approximately 3.9 billion active devices and holds roughly 72% of the global mobile OS market as of early 2026 — making it the world's most widely used operating system across all device categories.
Google acquired Android Inc. for $50 million in July 2005. That $50 million purchase is widely considered one of the greatest acquisitions in technology history.
Android 16, released June 10, 2025, introduced desktop windowing for tablets, Live Update notifications, Linux terminal support, and the Material 3 Expressive design language. Android 17 is expected in June 2026.
Android dominates every major emerging market — India (95.21%), Indonesia (86.8%), Brazil (81.45%) — while trailing iOS in the US (~40% vs ~60%).
Despite vastly more users, Android generates only ~30% of global app revenue vs iOS's ~70%, reflecting the higher spending power of the average iPhone user.
Huawei's HarmonyOS NEXT is the only current structural threat to Android, and is currently confined to China.
Android's open-source model, zero licensing cost for manufacturers, and Google ecosystem integration are the structural reasons for its scale — none of which are easily replicated.
Fragmentation — the spread of Android versions across billions of devices — remains the platform's biggest ongoing weakness, with meaningful percentages of devices still running Android 10 or older in 2026.
AI integration (Google Gemini, on-device models) is the primary growth frontier for Android in 2026 and beyond.
Actionable Next Steps
Check your Android version: Go to Settings → About Phone → Android Version. If you're running Android 11 or older, check whether your manufacturer offers an upgrade or consider a device replacement.
Enable automatic security updates: In Settings → Security → Security Updates, ensure your device applies monthly patches automatically.
Audit your app permissions: In Settings → Apps → Permissions, review which apps have access to your location, microphone, and camera. Revoke anything you don't recognize.
Evaluate your device's update commitment: Before your next phone purchase, check the manufacturer's published OS update policy. Look for devices that promise at least 4–5 years of updates. In 2026, Google Pixel and Samsung Galaxy flagship lines lead this category.
If you're a developer: Test your apps on Android 16 (API level 36). Check for layout issues on large screens and foldables — Android 16 now restricts apps that force a fixed orientation on wide screens, and Android 17 will make this mandatory. (Android Developers Blog, January 2025)
If you're buying a budget phone: Check whether the device ships with Google Mobile Services (Google Play, Gmail, Maps). Devices sold in markets where GMS is unavailable will have severely limited app ecosystems.
Stay informed about Android 17: Expect the stable release around June 2026. Follow the Android Developers Blog (developer.android.com) for official release notes and behavior changes.
Glossary
AOSP (Android Open Source Project): The free, publicly available core code of Android, maintained by Google and released under open-source licenses. Any developer or manufacturer can download and modify it.
API Level: A number that identifies each Android version for developers. Android 16 = API level 36. Apps declare which API levels they support.
GMS (Google Mobile Services): Google's proprietary suite of apps (Play Store, Gmail, Maps, Chrome, YouTube) that manufacturers must license to include on Android devices. Distinct from AOSP.
Linux Kernel: The foundational software layer that manages a device's hardware — processor, memory, power, and storage. Android is built on top of a modified Linux kernel.
OHA (Open Handset Alliance): A consortium of 34+ technology companies including Google, HTC, Samsung, Qualcomm, and T-Mobile, formed in November 2007 to develop open standards for Android.
AOSP ROM / Custom ROM: A version of AOSP modified by independent developers (e.g., LineageOS). Popular among advanced users who want more control or whose devices no longer receive official updates.
Fragmentation: The state in which Android devices in the market simultaneously run many different OS versions, creating inconsistency in security, features, and app compatibility.
Material Design / Material 3 Expressive: Google's design language for Android apps and system UI. Material 3 Expressive (introduced with Android 16) adds increased animation, bolder colors, and blur effects.
Sideloading: Installing an app from outside the Google Play Store by downloading an APK (Android Package) file directly. Allowed on Android; not natively allowed on iOS.
APK (Android Package Kit): The file format used to distribute and install apps on Android, similar to an .exe file on Windows.
HarmonyOS NEXT: Huawei's proprietary operating system, launched on new Huawei devices in 2024–2025, which runs no Android code and competes directly with Android in China.
One UI / MIUI / ColorOS: Manufacturer-specific Android skins from Samsung, Xiaomi, and Oppo respectively, that change the visual design and add features on top of base Android.
