I used to login from my Sony Xperia U to my PC but after the update (I don't know if it's just coincidence or not), when I try to login to my PC from my Android Sony Xperia U, I see the screen turns to deep blue to my PC. My Android device shows connected and after one second or less, shows that the session successfully ended. I uninstalled, I reboot my mobile and re-installed Teamviewer on my Android device. On the other hand, I have used both version 8 and 9 (full and quick support) to my PC but this problem keeps on existing. I also tested another application that connects mobile with PC and it's working fine (Splashtop). I'm really wondering what is wrong because it's not that I can't login, but the session ends automatically after one second. Is it the firewall? I have disabled the firewall and it keeps on doing that. If the problem is the settings of my firewall, why was it working fine few months ago?
P.S: Just in case, the resolution of my Android phone (Sony Xperia U) is 854 x 480 and my PC's resolution is 1680X1050 (Windows 7 Ultimate and I use Comodo firewall)
