The Android smartphone ecosystem boasts more than 100 brands, each with their own portfolios and peripherals, targeted at niche users, or the general population. There are some smartphones that specialise in cameras, some that specialise in gaming performance, while there are some that cater to all your needs, in a jack of all trades kind of fashion. The one thing that stays common across these smartphones is the operating system. The Android operating system is what makes all of these smartphones behave and perform the way they do, and thanks to the open source nature of the source code, the OEMs are allowed to modify the OS to suit their smartphones and their brand.
Today, the Android smartphones are divided into two distinct categories –
Number 1. The smartphones that run stock Android
Number 2. The smartphones that run a custom UI based on Android
