Amoled screen discoloration (this time it stays )

[john10]

I've been using this phone no crack on screen then suddenly may glitch na discoloration and tried to factory reset and for a short while it's gone and its back again.

My brightness is always set to low w/ night mode and extra dim and eye comfort im using A71 

Already tried factory reset(it always comeback and return again)

Can anyone tell why this happens especially even I'm not a heavy user and can you suggest any trouble shooting to fix this aside from factory reset(did that already)
