The Samsung Galaxy Tab A7 Lite announced last May with Android 11 based One UI 3.1 gets Android 12 with One UI 4.1 on top.
The new update brings a revamped UI and the usual Android 12 and One UI 4.1 goodies to the Galaxy Tab A7 Lite, in addition to the July 2022 Android security patch.
The firmware carries version number T225XXU1BVGB and is in production for the Galaxy Tab A7 Lite sporting model code SM-T225 in Hong Kong and Germany. The rollout will hopefully be expanded to other models and regions soon.
If you live in Hong Kong or Germany and have not yet received the Android 12 update on your Galaxy Tab A7 Lite, you can check it manually by going to the Settings > Software update menu.
