As of last Saturday, every 6 minutes my Galaxy S20 5G will open the Messages app for a fraction of a second then return to whatever I was doing previously. I initially thought it was just the screen orientation bugging out as it always returned me in portrait view, however upon closing all apps but the one currently in use (Youtube, Twitch.tv or a mobile game) I noticed that after the flicker I'd have a blank Messages app open after pressing the Recent button. Tapping this app would appear to crash it instantly and return me to my home screen, but opening the Messages app from it's icon would have it occupy the same space in Recent so I don't think it's some other app using the same icon. I've not installed a new app on my device in at least a month save for Bitdefender today to see if it could find any problems. The only notable change was the system update on Saturday morning, as I exclusively use the phone for playing 1 mobile game (Arknights), texting and watching Youtube/Twitch.
I've booted my device in safe mode and the problem persists unchanged, I've tried clearing my cache to no avail and both my device and Messages are up to date.
Any help before I'm forced to attempt a factory reset?
I am having the same issue. My question is if I toggle off "appear on top" it sounds like this will stop the messages app from briefly appearing over top of whatever I happen to have open on my screen at the time... But will it stop the messages app from showing when I press the recents soft button? Because otherwise I can't quickly switch between my last two apps by double pressing the recents button quickly.
The Recents Swipe or Button is only intended to allow you to quickly switch between recently opened apps. I don't THINK, that a notification would be treated as a recently opened app.
But the messages app actually opens briefly for a split second overtop of whatever app you happened to be using at the moment. So when I would try and toggle to my last used app by double pressing "recents", it would try to open the messages app, but because this is a glitch in the software the screen just flickers and then defaults back to my home screen.
If you don't already have Google Messages installed on your device, then I'd suggest that you download it from the Play Store & set Google Messages as your Default Messaging app.
This *SHOULD* "fix" the issue until Samsung pushes a fix for Samsung Messages.
FYI, Samsung is moving to replace Samsung Messages with Google Messages anyway, or so it seems.
