All of a sudden my screen has a horrible red tint. It appears to be a software issue because when I reboot the phone, the booting logos are all colored properly. Also - the navigation bar is not tinted red, only the rest of the screen. When I play a full screen video the navigation area also turns red. That indicates to me that this is a software problem. I disabled all of my xposed modules and switched back to the stock launcher but it's still red.
Next step unfortunately will be to factory reset or flash a new rom but I'd really love to avoid that. Any idea what might have caused this?
Recovery screen is normal colored as well. The only modifications I've done are root the stock rom, install greenify, Xposed, and G2Xposed.
Edit: Solved, it was the Lux app. Weird. It's been working fine for me for months and wasn't updated today.
