Can't give display over other Apps permission Motorola e7i
I just bought a Motorola e7i with the intention to leave it as remote device to monitor a machine. When I now wanted to install Teamviewer host and I get prompted to give teamviewer the permission to "Display over other apps". However I cannot do it. I can go to the permission page but there I only get told that this feature is turned off because it slows down the phone. I checked if any power saving options are turned on but couldn't see anything I could turn off.
Also the Host app is refusing to jump this step and only give me the possibility to go to the respective settings page (where I cannot do anything) or cancel. If I cancel I get an immediate notification that this still outstanding?
Any suggestion to make this work? Would rooting the phone help? Motorola is on the list of supported devices.
Please move this entry if it already is discussed elsewhere but my searches with google and here did yield nothing. I successfully remote control an Samsung active tab with my account.
