S21 behaving like random bugs

[Alpha_Dev]

Yesterday I tried to fix UPI buttons it was showing half button when making a payment. I enabled easy mode and the dpi gone 4032 & when I unlock phone , display go off & then lock screen. The texts & view became so big that I can even check what going on..

Fast forward I managed to fix it by using external keyboard after wasting 5hrs..

& now the gestures navigation not working & the drop down settings button not working , holding power button doesn't show up anything, no recent apps showing, animations became trash.

Notice the left back arrow.

Note- I have checked in safe mode , cleared cache , repaired apps but nothing works, deleted good lock Navistar nothing works. 

Any solution will be appreciated 👏

Your phone support good lock but you are using fine lock ?

I was debugging the issue , someone on the forum mentioned that delete Navistar and uninstall Goodluck but that doesn't worked for me , so I had to install it back.

Go to recovery mode and use repair apps option.
If it doesent help then take backup(not of setting)and reset
And clear cache partition

Mark it as solution please

Repair apps option not working, it's just booting normal. Data is around 100gb failing multiple times. Taking cloud backup for now.
