Google has rolled out Project Treble support a couple of years ago with Android 8.0 Oreo. So, the Android Oreo higher version running devices to be compatible with a generic system image (GSI) of stock AOSP Android. It helped many developers and smartphone OEMs to create Custom ROMs and provide faster updates for certain devices easily. Currently, Google officially supports GSI and allows you to install Android Q on any Project Treble compatible device. That’s great. Isn’t it.
The GSI will always be able to install the latest stock Android officially from the manufacturer directly and quite faster as well. You don’t need to depend on any Custom ROM developer for upgrades. The Stock Custom Skins like One UI, MIUI, OxygenOS are quite stable and keeps updated every time for better user experience.
