When I use my Gear VR (SM-R324) after I did not use it for a while (some hours), the controller does not connect. I press the home button for a while as described in the manual. The LEDs flash forever, but there is no connection. Even if I try this several times. I manually have to disconnect the controller in the Bluetooth settings of Android and then reconnect it. Which results in having to calibrate it again, a search for firmware updates and I have to set the used hand for it again. This always takes a lot of time. And when I do not quickly put on the headset, the connection is lost again as soon as the controller goes into energy saving mode.
Is this the usual behaviour of the controller? I guess not. It should reconnect automatically every time I press the home button, right? My phone is a Samsung Galaxy S8+.
