Host app crashes after a minute on Samsung
Having issues with TeamViewer Host on Android. It's a new device, Samsung Galaxy Tab A, running Android 9.0, fully updated. My remote access to the mobile device works fine, for all of a minute, then the Host app crashes.
I can then reconnect, for a minute again, and then it crashes again. I'm unable to reconnect after that; the standby mode is never exited.
The device in question is used for my grandmother who's in her 90s, and has difficulty hearing and more recently seeing, so a remote access to help her with using the device is very necessary. A few nights ago I had to talk to her for a full hour just to turn off a single setting, because the Host kept dying.
Any help is appreciated. It's a new device, minimal stuff installed, it was updated in OS and Play Store.
