I have samsung galaxy a51 bought it few months ago. From the very starting facing a lag/stuttering issue while opening and going through apps, i have full screen gestures enabled.
I have the latest one ui 2.1 installed on my device.
Before commenting any solutions please keep in mind -
1. I have already cleared cache partition thrice.
2. I have tried to run this in safe mode for almost an hour.
3. Tried to restart/switch off
This problem might look very miniscule but its not every two or three days after the restart the phone works good for only 3 - 4 days after which it laggs/stutters badly while opening and moving all apps tab.
I hope samsung fix this bs issue with Android 11 one ui 3.0 otherwise they gonna loose a loyal customer, however it looks like they don’t even care at this point.
no to anyone reading this thread don't waste your time on something you can't fix. Rather wait for a fix by samsung themselves hope they will see the problem and fix it in future update, restores doesn't help in case of optimization problem its something samsung developers can fix
