Since a few days I have this problem with my Fold 3, but only the small displays. Opened I don't have any problems.
I've searched for this problem, but could not find anything similar, only for the complete phone.
I have already done a cache reset and tried a save mode check. The problem persists, so it's most likely not a problem with one of the installed apps.
I would, however not do a factory reset, as I'm running a company profile too and it is a pain to reset this.
If this is correct, would it be a warranty case depending on the age of the phone?
@JuergenH1 to determine if this is an installed app I'd suggest to run Safe Mode.
> Safe Mode > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict.
In regards to using a Samsung Service Centre they will assess the phone and then advise you whether a phone is faulty or not and if any required work is covered under the Samsung Limited 2 Year Manufacturers Warranty.
If I can be of any further help then please don't hesitate. Take care. 😎
