*Hello, if you have an Android device, and if you enabled Developer Mode and selected an option that gives you a visual screen update flash, this is why. Please turn off the "Show Screen Updates" and/or "Show GPU view updates" and/or "**Show hardware Layers updates"
*''Please note, these instructions only apply to Android Devices, if you do not have an Android device, or if your phone has visible damage, the screen's pixels may be disfunctional.''
* *''According to the developer options screen, the Show Hardware Layers Updates makes hardware layers green when they update, and this may be causing your issue.''
