prantik_karan , via OnePlus 9 Pro , Jan 22, 2022 : I upgraded to Oxygen os 12 and it's one of the worst experience I am having. The themes are bad. Game mode is the worst. Os11 game mode was good. In Oxygen OS 12 game mode keypad covers the whole screen. Instagram too doesn't open now. Message notifications are also not coming on lock screen. anyone facing the same issues ?
