After update my Galaxy m31 to Android 12 there lots of bug like vibration and slow device. After update I am not able to play COD game. Already raised these bugs but still not received any response from Samaung Team. 

Totally dissatisfied...🤔

Reset you device once.....after every big update do this once if you face lag issues

Hey Amit,

I too have a M31 device and what I did post update was go to Settings> Apps/Application Manager >  Select Storage > Clear Cache

Once this is done try rebooting your device by restarting it, it will perform in the same way as it did earlier.

Tried this but not solved.
