Yellow screen problem

Hi. I have a HUGE problem with my screen in ma RN3P. Always when i install new ROM (Tried about 6/7 with android 5.1,6,7. Same problem with them all) a the start i see only "Theme chooser stopped working" and my screen is becoming yellow like in Reading mode. I did not change kernel. Thank you all for help
This is not a problem it is a feature known as live display. You can turn it off in settings > display>live display.

LCD Problem

Hi all,
i really dont know what happened to my phone. the screen turns black instantly after showing the samsung logo on the start up i tried to reflash a fresh firmware but didnt do the job. the screen is showing the download mode also but after restarting and showing the samsung logo the screen turns to black. sometimes it flickers and shows some of the screen but turns off instantly
is there any fix to this ? does my phone encountered a water damage ? i tried the water damage test on the sim tray but the sticker seems to be on its original state no water damage at all any assistance would help i hope the lcd is not broken my country is on a lockdown and service centers open at this moment. i really need the phone for my work
Thanks
you have to turn on AOD to fix this I guess because I had a similar issue with my screen so a temporary fix is to turn on AOD then press power button screen will work fine pressing the power button directly when the screen is off flickers it and the screen turns completely black after a weird yellow flash.
