you can reproduce and report it to samsung using samsung members app > get help > error report.
Try using Nice Catch to see what is changing the settings
Mine is doing the same thing and it's beyond annoying. I signed on here to try and find a fix. Seems to have started after last update. No matter how many times I correct it, it does it every time I snooze my alarm - and then the phone lights up the room because of the "colors" screen saver - instead of the clock screen saver I chose. Samsung needs to correct this.
go to settings > about phone > software information > build number (last 4 digit) and share the software version that is running please.
If I recall correctly this is occurring on various models, so it's not exactly model specific rather I'm assuming something to do with the latest app or feature update.
Reproduce and report as noted above
Same here. A71. I use a clock app as my screensaver. Starting this week sometime, the phone randomly and automatically sets the screensaver back to 'colors' about 2-3 times a day.
update is not always the same for everyone. the updates vary per model and also carrier as well as whether you are using unlocked or carrier locked device.
so... it is very important to make note of the software version, NOT the month of update.
if you need to check the software version the phone is running, go to Setting > About Phone > software information > build number (last 4 digit)
when mentioning updates or any issues be sure to make note of the software version so a proper trend can be made. Otherwise the trend created may be misleading.
