I have a Samsung S8 + Oreo 9 One UI 1.0 phone. I have installed team viewer host. Previously, add on samsung worked without a problem. Now when I use Knox I have a problem with the active connection. The connection works for a maximum of 2 hours. You must restart your phone later. After that it works again for a maximum of 2 hours. I have already switched off eco mode. I removed the battery optimization. It did nothing. It does not matter if it is in the optimal battery mode or in the saving mode. There are days when the host is operating normally. A few hours work and the problem does not occur.
