Google's mobile operating system began its journey more than a decade and a half ago, radically changing the smartphone market. Since the release of the first commercial version in 2008, the platform has undergone a huge evolution, turning from an experimental project into the most popular OS in the world. Users often wonder how many versions of Android were released during this time and how the numbering changed.
Today, the ecosystem has 16 major releases, if you count the very first commercial build, and continues to actively develop. Each new iteration brings not only changes in the number, but also revolutionary updates to the interface, security and performance. Understanding the history of updates helps gadget owners better understand the capabilities of their device and plan its replacement.
In this article we will analyze in detail the chronology of all releases, explain the naming logic and provide up-to-date data on device support. You will find out which versions have already become history, and which continue to receive security updates right now.
The era of formation: the first steps of the platform
The story began with the release Android 1.0, which appeared on the first commercial smartphone HTC Dream in September 2008. This version was extremely basic: it lacked many of the features we are used to today, such as a virtual keyboard (input was carried out only with a physical QWERTY keyboard) and multi-touch support. However, it was this release that laid the foundation for the future ecosystem, introducing the concept of widgets on the home screen and integration with Google services.
Soon after this, a version was released, unofficially called Petit Four. This update fixed many bugs and added support for displaying details in maps, as well as the ability to attach files to messages. However, the real breakthrough came with the release Android 1.1, which received the unofficial name Petit Four. This update fixed many bugs and added support for displaying details in maps, as well as the ability to attach files to messages. However, the real breakthrough came with the release Android 1.5 Cupcake in April 2009. It was with this version that the tradition of naming updates after sweets in alphabetical order began.
Cupcake brought users the first virtual keyboard, support for widgets in the full sense of the word, and the ability to record videos. The system architecture has become more stable, which has allowed third-party developers to more actively create applications. Version 1.5 was the first mass release that showed the potential of the platform for the average consumer.
⚠️ Attention: Devices based on versions 1.0–1.6 are today considered museum pieces. Most modern Google applications and services have completely stopped supporting these builds, so it is not safe to use them for everyday tasks.
Why do the names start with the letter C?
The first two versions (1.0 and 1.1) did not have public names for sweets. The internal working version 1.2 was codenamed Apple Donut, but was cancelled. The public release of 1.5 was named Cupcake, and the tradition stuck, although the letters A and B were omitted from the public space.
The Golden Age of Sweets: From Donut to Jelly Bean
The period from 2009 to 2012 was characterized by a rapid rise in the popularity of the platform. Version Android 1.6 Donut brought support for various screen resolutions and CDMA networks, which opened the door to entering the American market. It was followed by Android 2.0/2.1 Eclair, which became the standard for smartphones of that time, introducing live wallpapers and an improved browser.
Android 2.2 Froyo (Frozen Yogurt) occupies a special place in history. This update significantly speeds up the system by introducing JIT compilation, and also adds support for Wi-Fi access points. For the first time, users were able to install applications on a memory card, which was critically important given the small amount of internal memory of those years.
The era of Gingerbread (Android 2.3) and Honeycomb (Android 3.0) divided devices into smartphones and tablets. While Gingerbread optimized the interface for small screens and introduced a task manager, Honeycomb was created exclusively for tablets with large controls. However, the real hit was Android 4.0 Ice Cream Sandwich, which combined the phone and tablet versions into a single universal system.
- 🍩 Donut (1.6): Support for different screen resolutions and networks.
- 🍦 Froyo (2.2): The emergence of a Wi-Fi access point and JIT compilation.
- 🍪 Gingerbread (2.3): Improved keyboard and copy/paste text.
- 🍭 Lollipop (5.0): (Published later) Design Material Design.
This stage is completed by the era Android 4.1–4.3 Jelly Bean. The main innovation was technology Project Butter, which made animations smooth and responsive, eliminating interface lags. There was also a smart Google Now search bar, which anticipated the advent of modern voice assistants.
Material design and optimization: KitKat and Lollipop
With the release Android 4.4 KitKat in 2013, Google changed its naming strategy, choosing the popular chocolate instead of a lesser-known dessert. This version was optimized to work on devices with low RAM (from 512 MB), which made it possible to run modern Android on budget smartphones. The system has become lighter, and the navigation panel has acquired a transparent appearance.
The real revolution occurred with the release Android 5.0 Lollipop. The implemented design Material Design changed the visual language of not only Android, but also all Google services. The interface became flat, bright and used depth and shadow effects. Under the hood, the Dalvik runtime has been replaced with a new environment ART (Android Runtime), which speeds up the launch of applications and the operation of the system as a whole.
Version 5.1 made important improvements to working with multiple SIM cards and added device protection against theft (Factory Reset Protection). Now, when resetting the settings, it was necessary to enter a Google account, which made the theft of smartphones less profitable. The transition to ART compilation in Lollipop became the most significant technical change in the entire history of the platform.
⚠️ Attention: Applications developed for older versions of Dalvik may not work correctly or require reinstallation after updating to Lollipop and higher due to differences in code compilation.
If your smartphone runs Android 5.0 or lower, check your browser for HTTPS support. Many modern sites no longer open on older versions of the system due to outdated security protocols.
Focus on intelligence: from Marshmallow to Pie
Starting from Android 6.0 Marshmallow, developers have shifted the focus from visual changes to functionality and rights management. For the first time, users were able to flexibly manage application permissions: they could deny access to the microphone or contacts for a specific app directly in the settings. A function also appeared Doze Modethat significantly saves battery power in standby mode.
Android 7.0 Nougat brought long-awaited support for multitasking in split-screen mode. Now users could simultaneously use two applications, which was especially convenient on tablets and smartphones with large diagonals. The same version introduced support for the Vulkan API for more productive 3D graphics in games.
The era Android 8.0 Oreo i Android 9.0 Pie was marked by the introduction of elements of artificial intelligence. The system has learned to predict user actions, adapt screen brightness and optimize background processes. Pie now comes with Adaptive Battery, which limits the operation of rarely used apps to extend battery life.
- 🍬 Marshmallow (6.0): Granular control of app permissions.
- 🍫 Nougat (7.0): Split screen and quick switching between apps.
- 🍩 Oreo (8.0): Picture in picture and autofill passwords.
- 🥧 Pie (9.0): Adaptive brightness and digital well-being.
The Pie version also changed the navigation: control gestures appeared, which gradually replaced the traditional Back, Home and Menu buttons. This paved the way for full-screen smartphones of the future.
☑️ Checking readiness for update
Modern era: from Android 10 to Android 15
With the release Android 10 Google abandoned public names in honor of desserts. This decision was dictated by globalization: the names of sweets were often unclear or untranslatable in other cultures. The system now uses simple digital numbering. The tenth version brought full support for a dark theme at the system level and improved privacy controls.
Android 11 focused on the convenience of communication and control of a smart home. Notifications from instant messengers were moved to a separate block, and control of IoT devices (lamps, sockets) was added to the quick settings menu. Android 12 presented a design Material Youthat allows the system to automatically adjust the interface colors to the user's wallpaper.
Latest versions, including Android 13, 14 and 15, continue to develop the topic of privacy and personalization. In the 13th version, a separate language switch appeared for each application, and the 14th introduced partial access to media files so that applications did not see the entire gallery at once. Android 15 introduces the "Private Space" feature, which allows you to hide certain applications behind an additional password or biometrics.
⚠️ Attention: The interface and names of menu items may differ on smartphones from different manufacturers (Samsung, Xiaomi, Pixel). Manufacturers often add their own shells on top of pure Android.
The abandonment of the names of sweets after Android 9 simplified communication with an international audience and made version numbering more understandable for users.
Summary table of versions and key features
For ease of perception of the entire history of updates, we have prepared a summary table. It reflects the main milestones in the development of the platform, allowing you to quickly find information about a specific version.
| Version | Code name | Release year | Key feature |
|---|---|---|---|
| 1.5 | Cupcake | 2009 | Virtual keyboard, widgets |
| 2.2 | Froyo | 2010 | Wi-Fi access point, installation on SD |
| 4.0 | Ice Cream Sandwich | 2011 | Unified system for phones and tablets |
| 5.0 | Lollipop | 2014 | Material Design, ART environment |
| 10 | (no name) | 2019 | System dark theme, gestures navigation |
| 15 | (no name) | 2026 | Private space, satellite connection |
As can be seen from the table, the pace of development of the platform remains high. Google aims to release a major update annually, usually in late summer or early fall. This gives smartphone manufacturers several months to adapt firmware before the mass release of new devices.
⚠️ Attention: Support for Android versions will not stop immediately. Security updates may arrive for another 1-2 years after the release of the next major version, but functional innovations are only available on current releases.
How to find out your Android version?
Go to the menu Settings → About phone → Android version. There will be a version number and, on some devices, the logo of the corresponding sweet when pressed multiple times.
