My device has problems flashing the screen when the brightness is low, specifically about 40%. This is very uncomfortable when used at night. I'm not sure when it started but probably when upgrading to the Q. version. Does anyone have a fix for this problem? I plan to downgrade to the P version. 
I have used the Oled saver app on CH Play but it is quite good but I do not like it working by pushing the brightness to the maximum and then overlaying another layer.
