LineageOS-19.1 For Samsung Galaxy M20 [UNOFFICIAL]

Edited on August 11, 2022

LineageOS is a free, community built, aftermarket firmware distribution of Android 12, which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed.
