But my phone never falls, why is this problem happening after updating? Service center people are asking to change the display or it will cost Rs 9000.

I have also done this diagnostic test but the display of my phone has turned brown, earlier it was very dark black. This problem has been going on since Samsung has sent the update but the company is not giving any updates so how can this problem be ...

Everything is the same as before, there has been no change even after the format.

@samsungindia Everyone is facing display problem in their phone, go to the service center first you fix your software issue. Because same problem facing in my phone after your update.

No update
