Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008.
Most versions of Android are proprietary. The core components are taken from the Android Open Source Project (AOSP), which is free and open-source software (FOSS) primarily licensed under the Apache License. When Android is installed on devices, the ability to modify the otherwise free and open-source software is usually restricted, either by not providing the corresponding source code or by preventing reinstallation through technical measures, thus rendering the installed version proprietary.
Most Android devices ship with additional proprietary software pre-installed, most notably Google Mobile Services (GMS) which includes core apps such as Google Chrome, the digital distribution platform Google Play, and the associated Google Play Services development platform.
Android has been the best-selling OS worldwide on smartphones since 2011 and on tablets since 2013. As of May 2021, it had over three billion monthly active users, the largest installed base of any operating system, and as of January 2021, the Google Play Store featured over 3 million apps. Android 13, released on August 15, 2022, is the latest version, and the recently released Android 12.1/12L includes improvements specific to foldable phones, tablets, desktop-sized screens and Chromebooks.

The 2022 version of Android allows you to auto-theme your icons just like you theme the rest of the operating system with Android 12.
The OS update also extends the available color-theming options by offering six new palettes relating to specific shades or complementary hues.
Android 13 lets users toggle between two clock styles on the lock screen. Users can select a single-line layout or the current double-line layout.
The media player that appears in your notification area has a new look. Album art now takes up the entire background of the widget and the controls have been moved around a bit.

There is now a quick toggle to launch a simple QR scanner right from your notification tray.
Wireless audio gets a boost in the newest version of Android. It has baked-in support for Bluetooth LE Audio and the Low Complexity Communications Codec (LC3).
If you’re multilingual, this might be the best addition to Android 13: per-app language toggles. This allows users to set specific languages for specific apps, separate from the system setting.
In December 2022, Google announced a digital car key feature that would let users unlock, lock, or switch on their compatible rides with their phones. Users can also share the key with friensd and family.
At the Pixel 7 launch in October 2022, Google announced a new privacy and security hub for Android 13. The feature makes managing privacy and security features easier by housing all these Android 13 settings and using action cards to prompt responses from the user.
When you share a document with an Android app, the document picker that pops up is pretty secure. It doesn’t allow the app to have access to all your documents, just the ones you select.
Fast Pair is a terrific feature. It allows you to quickly pair your phone to accessories, such as Bluetooth headphones. Instead of needing to manually add them, your phone will simply alert you that something is around and ask you if you want to pair with it.
Under-the-hood upgrades
Under-the-hood upgrades
It is now easier to format Japanese text so it is more readable and polished.
Non-Latin scripts (Tamil, Burmese, Telugu, Tibetan, etc.) now look better with adaptive line height. This prevents the bottom sections of these characters from getting cut off.
People who use phonetic lettering (such as those who speak Japanese and Chinese) will now have an easier time conducting searches and having texts auto-complete. This is because of a new text conversion API incorporated into Android 13.
Fonts and emoji will have rendering support from COLRv1. This will help them render quickly and to look great at virtually any size.
