Hope someone can help, as I have searched everywhere but can't find the answer. Also not sure of the correct term to use (glitch/flash) for the issue I'm having. Certain apps on my phone flicker and flash white screen, just for a couple of seconds approx every 6 minutes then return uninterrupted on the app. If using the phone landscape the phone reverts to portrait, flashes with a white box. For example on Directions on Google Maps - map disappears - screen flashes white for 1 or 2 seconds, then returns to directions. It's as though something is interrupting the app. The exact same thing also happens on a poker game and on messenger. I have uninstalled and re-installed apps, all phone is updated, I have turned down the brightness and I have cleared all cache. Appreciate any suggestions on have to fix. Cheers....
Hi, I have only noticed it happen on these apps, as these are the apps I use the most. It also happens on whatsapp. I will please the phone in safe mode, as suggested, and monitor. Thank you.
I can confirm this is a genuine software issue as I have the same problem with a white flash every 6 minutes (checked with a stopwatch).
The problem started happening after the messaging app (after an update) prompted me to use advanced chat features (and collect additional data) - I selected to continue without advance features. Then I noticed the flashing started after this. Once the flashing happens, if you check the recent/open apps screen you'll find the messaging app is in the list even though it previously wasn't opened. You can close all apps and then wait 6 minutes again and you will see the messaging app again.
Samsung - please issue a fix for this problem!
I seem to have fixed this by going into settings, choosing "default applications", finding the entry for "Messages", and changing it to turn off the "Appear on top" option.
