Display issue on samsung s9

[sejet86196]

Display issue on samsung s9. Screen goes dark on adaptive brightness (often after like 4-5 hrs). If I adjust the brightness to anything below 60%, it goes real dark (with or without adaptive brightness). For now I have kept the brightness to max. Seems to work now. But looks like over all the brightness of phone is bit reduced.

Been using this phone for past 4 yrs tho. No issues till now.

A factory reset may help.

Your issue ...Screen goes dark on adaptive brightness (often after like 4-5 hrs).... The 5 yr old battery may be causing that

This is a hardware issue, take it to a repair shop. Nothing we can help you with.

A problem with the matrix. You will probably have to replace the screen.
