SCREEN

Today I was calling someone and suddenly lower end of my cell phone showed dead pixels for 1 second and then disappeared.  Should I be worried? What might be the reason?

My cellphone is a52s

If display was under any pressure from your face or from your hand and as you remove pressure dead pixels gone then this might bhi panel problem.

If display wasn't under any pressure, then it's only ka software bug. You don't need to be worried.

-bright chances are that it's a software bug, because when display fails, you see either see a line, brightness drops, or black dot.
Pixel disappearance is not reported in Samsung displays.

In some apps screen starts blinking from below. For few seconds. Is it panel's fault?

I am also using A52s and I use many apps. Almost every usable app in these days. I haven't seen this issue in my mobile yet.
But may be there's culprit app which runs in background and cause this issue

If you want to confirm root cause, try resetting your Device once and for few days only install and use basic apps. If you still se this issue after resetting, then there are pretty chances that it's hardware issue.

Assalam-u-Alaikum!

Brother I read on internet, it's a known issue in A52s.
But glitches appear only when you're on 2G and receive a call.
It's not a software fault, it's purely hardware fault. But you can avoid it by changing network that's signals are better in your area. Or you can set your sim to 3G/4G.
Don't set your device to 2G.
This flicker only shows when device is on 2G and you receive a call in Poor Coverage area.
