This is totally unreliable. I have to constantly go through the "recommended" procedures of turning off my wifi, then turning off my bluetooth, turning it back on again to get it to connect. Even then it will only be either the right, or the left or not at all. I also did the uninstalling then reinstalling, this app, its very discouraging. I will miss important phone calls because I never heard the ring due to it disconnecting without warning. Fyi, I am using the latest Oticon 5 instruments.
