I've recently updated my samsung s6 edge to android 7.0 and now host seems to go to sleep after a period of inactivity. Unattended access was working fine before but now seems to time out.
Same problem here. TeamViewer shows Android devices in standby when the screen timeouts and locks so you cannot connect and remote control. Tried different smartphone brands and Host for Samsung as well as TeamViewer Host on Android version 7. It does not show online again until the device is unlocked and you switch to the host app to get to display "Ready to connect".
This did not happen with previous Android versions so you could remote control and unlock. Can someone please investigate fix this bad bug/malfunction?
