Background
Android is an open-source operating system designed for mobile devices and was first introduced in 2008 with the launch of the HTC Dream. Originally developed by Android Inc., the software was later acquired by Google in 2005 and has since undergone several iterations, culminating in the latest release of Android 14 in 2023.
Beyond smartphones and tablets, Android has also been adapted for use in other devices like digital cameras, smartwatches, game consoles, and PCs.
The most often replaced Android Phone parts include the battery, screen, and motherboard.
Identification
As the world's best-selling mobile operating system, Android powers a broad range of devices from various manufacturers, including Samsung, Oppo, Google, and Motorola, among others. You can verify that your device is running on Android by navigating to the "About Phone" section in the system settings, where you can find manufacturer information, the model number, and the current Android version running on your device.
The model number and manufacturer can also often be found on the back of the phone.
Versions
Google famously named Android versions after sweets, such as "Cupcake" for v1.5, until the release of Android 10. However, starting with Android 11, Google moved away from this naming scheme and began using numbers instead. The company stated that this change was to make the version names clearer and more accessible to a global audience. These codenames are now used only internally within Google.
