Yellowish border

[Hari3]

I got my galaxy A23 mobile on 2021 and now all of sudden today It showed yellow border on the right side and top of screen. I did checked all the setting and blue lift mode and everything that online said and even did dial check I got those lines even when I on green,blue screen. What should I do ? #galaxyA23 @samsung

I'd suggest to let a Samsung Service Centre have hands on with your phone @Hari3 

If I can be of any further help then please don't hesitate to ask.  😎
