Hmm.. I used wifi connection and I was under impression I need to run that cmd line Epic has in their docs and then run the game. This way the phone is always in GearVR.

I'll try it your way now, thanks.

Yeah, you can also do it with adb over wifi. It is even easier - run 'adb logcat -c' at the beginning and 'adb logcat -d >log.txt' to get full log. You may add filters via -s option too.

Alright, here we go:

A. Removed phone from GVR without exiting to Home (after phone was removed my app was not running): https://drive.google.com/open?id=0BwE6dxM0O2PsVHFrTzY3TFNkQlU

B. Removed phone from GVR after exiting to Home (after phone was removed my app was still running): https://drive.google.com/open?id=0BwE6dxM0O2PsS3VGdHQxMDVaRjg

Yeah, it seems working:
D/UE4 (28611): [2016.04.07-01.59.59:261][64000]LogHMD: GearVR shutdown.
D/UE4 (28611): [2016.04.07-01.59.59:307][64000]LogWindows: FAndroidMisc::RequestExit(1)

Why do you think it doesn't exit? If you refer to the "ghost app" that you still see if you press the Tasks button on the phone, then I can say it is not a real app. If you select it, the app will be started from the beginning. I don't know why that 'ghost app' stays in the tasks, seems like this is how the System.exit(0) works on Android (see implementation of AndroidThunkJava_ForceQuit() in Engine\Build\Android\Java\src\com\epicgames\ue4\GameActivity.java

I see, thanks! I thought it doesn't exit because the "ghost" app was hanging in the Tasks. Indeed, if I tap it, it will start as if I just ran it fresh.

Sorry, I didn't know how that works and I wanted to make sure it wouldn't affect performance of other apps that people might run after leaving my app/game. Better be safe than sorry, right? :blush:

While this is probably the case i don't see it with any of the apps available trough Oculus home. Since the majority are made in Unity, maybe it's Unreal thing? Do we need to poke Epic about that?

Feel free to raise your concerns to Epic, since it might be UE4 issue: https://answers.unrealengine.com/questions/396823/gear-vr-how-to-shut-down-app-on-exit-to-the-store.html

Maybe if several people express concerns over same issue, they might look into it.

This is a good question. I'll discuss this with our mobile guys too.
