Display issue

[moonnn]

Hello guys, am having an issue with the display of my samsung a71. The blacks on my screen are purple, i did get this issue a few months back but it had gone but now it came back. Sometimes when I adjust the brightness to a certain level the blacks becomes normal but not for long and also the AOD blacks and the off screen which displays the charging information also is purple. Does someone also have this issue? If someone knows the fix for this issue other than resetting the phone please tell me. 

Thanks
