Since my phone was recently upgraded to Android 11 has been a mess, the UI stops most of the time and you can barely enjoy the upgrade. I have a Samsung Galaxy A51. Has anyone experienced the issue mentioned before?
I've heard about many users reporting that problem, as well many users reporting the A51 is working perfect with Android 11, however, some people have said they made a factory reset when they updated the phone to prevent crashes like yours.
I recommend you to do that, and also to update all the apps, just make sure you backup all the important data before restarting.👌🏼
