A Brief History of Android: Company, OS Versions, Features

The first Android phone was running OS version 1.0 which was basic but had a set of Google apps like Gmail, Calendar, YouTube, and Maps. However, the real history of Android interface and functionality as we know it today started with Android 1.5, called Cupcake, in April 2009.

It had essential improvements, including auto-rotation, video recording, and the first on-screen keyboard that replaced a physical one. It also introduced a search widget and the framework for the third-party app widgets, which provides a flexible and customized home screen.

Shortly after the Cupcake, in September 2009, Android rolled out a new version — Donut. Most importantly, it involved support of the OS to work on a wide variety of screen sizes and resolutions.

Another new feature that set the ground for Android’s global expansion and imminent adoption by carriers around the world was support for CDMA-based networks like Verizon. On top of that, Donut included a Power Control widget to manage Wi-Fi, Bluetooth, GPS, etc.

The Eclair version came to light just six weeks after Donut. Despite such a short period of time, it brought significant UI updates such as live wallpapers and a drag-and-drop lock screen. Essentially, Android 2.0-2.1 introduced voice guidance for Google Maps and text-to-speech functionality as an alternative option to traditional keyboard input.

With the release of Froyo in May 2010, the users of smartphones supporting this version could switch on a Wi-Fi mobile hotspot and unlock the screen with numeric and alphabetical passwords in addition to a pattern lock.

Moreover, Froyo supported Android Cloud to Device Messaging (C2DM) service that allowed for push notifications.

At the end of 2010, Android 2.3, called after another sweet treat, Gingerbread, became available for mobile devices. The new OS version introduced an updated UI design with increased speed and simplicity.

It received support for NFC technology, provided capabilities for voice and video chat using Google Talk, and offered opportunities to use multiple cameras, including a front-facing one.

Honeycomb was the first Android OS version created exclusively for tablets and other large-screen mobile devices. As a response to the 2010 release of Apple’s iPad, Google rolled out Android 3.0 in 2011.

Among various improvements, it had a refined UI with the new Action Bar and enhanced multitasking. However, this was the only version that didn’t gain much traction on the market.

Moving on. In October 2011, Google announced a new version release named Ice Cream Sandwich. Android 4.0 brings updates in the user interface with the new font “Roboto”, soft buttons inherited from Honeycomb, and a built-in photo editor.

This OS version also supports users with new functionality to unlock the phone — biometric sign-in based on face recognition. Another enhancement was the ability to set limits when monitoring data usage.

Jelly Bean, launched in July 2012, introduced a smoother UI with significant performance improvements. Among other features, this Android version delivered plenty of new ways to interact with notifications, expanding action buttons. Now users could turn notifications off on an application-specific basis and respond to certain of them within the notification bar.

Another groundbreaking feature in Jelly Bean was multi-user support, which allowed up to 8 users to share the same device. It was also the first Android to include Google Now, a personal assistant, which was constantly becoming in demand at that time because of the rise of wearable gadgets.

Android 4.4, called after the famous sweets KitKat, was released in September 2013 and introduced several significant improvements. One of the most essential aspects was the optimization of the OS to run on smartphones with 512 MB of RAM, which enabled more devices to update software to this new version.

KitKat also got a refreshed look and feel with white elements replacing blue ones. Also, it was the first version that received the support of the “Ok, Google” voice command service.

A year later, in the fall of 2014, Google launched the Android 5.0 Lollipop OS version. It brought new features like Project Volta to improve battery life and Material Design with transitions and animations, as well as shadows and lighting effects. A newly implemented functionality, Tap and Go, allowed users to migrate data to a new device with NFC and Bluetooth technologies.

Unveiled in May 2015, the Marshmallow version was globally released in October, the same year. In essence, Android 6.0 got support for USB-C, a native fingerprint reader, and Android Pay, which we now know as Google Pay.

Google’s 2016 Nougat empowered smartphones with split-screen support, so two applications could run on the screen at the same time. It also introduced a customizable pull-down menu, a fingerprint swipe-down gesture, and a new set of emojis. However, major enhancements lied behind the scenes and included support for the Vulkan API and a new approach to future updates.

With the release of Android 8.0 Oreo in July 2017, Google introduced some visual changes to the menu. The biggest change, however, was the Project Treble delivery that represented a modular architecture to help hardware vendors keep up with new Android versions easily and quickly.

Plus, Oreo had a faster boot time. For example, compared with Nougat, it loads at 2X faster. And perhaps needless to say, this capability significantly contributed to user retention and gave the brand a strong competitive advantage.

At the end of 2017, with the release of Android 9, or Pie, the evolution of Android reached a significant accomplishment. So much so that this version remains the most popular to this day. It received a new home button that transformed into one elongated navigation button at the bottom of the screen.

Among performance boost, battery life optimization, and security enhancements, this version included Shush functionality to put your phone into a Do Not Disturb mode when the screen is placed down.

And probably the cherry on top of this Android version is its AI-powered features, like adaptive battery and brightness adjustment. The first one monitors consumption habits to help optimize battery for rarely used apps. While the second automatically adjusts screen brightness based on surrounding light conditions. Thus, making device usage way more comfortable.

Android 10 became the first version that has left behind iconic names related to desserts. Was it for a change in marketing strategy or a lack of well-known sweets, Google decided to name the OS versions using a simple numeric system.

In 2019, this new version got several significant feature improvements, security and privacy updates, a range of new APIs, and support for foldable phones that were about to come.

One year later, we could see another version of the operating system — Android 11. It provided more options to adjust notifications and contained upgrades to control smart home devices as the Internet of Things entered our lives, root and branch.

It also introduced some new features, like a screen recorder and chat bubbles that flow on top of the other app content and can be expanded or collapsed to facilitate conversations.

Next up was Android 12 which was released in October 2021. According to Android Developers Blog, it delivers a better user experience, enhanced power efficiency, and easier Wi-Fi sharing.

Besides other improvements, Android 12 receives a new UI with Material You, an updated design language for a more expressive and personal system.

Being released in October 2022, Android 13 continued to elevate personalization, security, and user experience. One of the core changes in this regard was the expansion of Material You. Specifically, Android 13 made it applicable to different apps, allowing users to adjust color themes beyond just Google apps.
One of the notable benefits of this Android version was the incredible multilingual support. This allowed people to choose their preferred language for individual apps, making them more accessible.

In October 2023, Google released Android 14. Overall, it continuously improved the capabilities offered by Android 12 and 13, especially focusing on a more user-centered design and security.

Plus, Android 14 supported font size increase up to 200%, while before that, users could increase it up from 130%. Additionally, the new version of Android expanded lock screen customization options, letting people pick from multiple clock and weather styles.

Ultimately, Android 14 supported the Ultra HDR image format. So, images taken by this Android start looking more vibrant and immersive.

One year later, Android 15 appeared on the market. Being highly focused on security and privacy enhancements, this version of Android came with AI-powered threat detection locks, which could immediately block the phone in case of any suspicious behavior detection.

Android 15 also offered users the ability to create a private space on their device, allowing them to double down on their private data and app storage in case of any breaches. Moreover, with 1080p cameras, users may enjoy high-quality videos and high-quality streaming.

2025 was the year of Android 16’s release. One of the remarkable changes in Android 16 was its desktop mode, allowing users to utilize apps on larger screens. So, whether watching content or checking documents, people can replicate it on a desktop and simplify things. Plus, desktop mode also supports keyboard and mouse.

Additionally, Android 16 incorporates the latest version of the Privacy Sandbox, which aims to deliver personalized content without compromising data privacy. With this feature, third-party cookies, which used to collect extensive user variables, become a thing of the past.

Instead, Privacy Sandbox employs different APIs, like the Topics and Conversion Measurement APIs, to group people and streamline targeted advertising, rather than tracking users across websites.

This Android version is on its way to market. As of February 2026, it is in the beta testing stage. Those who own a Google Pixel device can update and test Android 17. So, what’s new in Android 17?

One of the promising features of the new Android is Handoff, which will allow users to seamlessly switch between devices and continue tasks. Users will definitely appreciate such flexibility. Overall, Android 17 will also stay focused on large-screen adaptability, privacy tools, and app compatibility, leading to a better UX.

Android Studio is the official Android development tool, or, to be more precise, an integrated development environment (IDE) built on IntelliJ IDEA. It was first announced in May 2003 at the Google I/O — the annual developer conference held in Mountain View.

Android Studio supports various programming languages like Java, Kotlin, C++, and Go to provide vast opportunities for building applications for every type of Android device.
