After the major Android update the Eye Comfort Shield feature has been turning on and off randomly. For Gallery it's ok to turn off but every single random app nah...It's now at a point where it adjusts more than the auto-brightness.
I just received my new M52 today and it's showing artifacts on one side of the display. I upgraded from M30 and never had this type of issue with that before.I have taken some pictures to show the issue in a dark room where it's visible to the camera...
