Does it have Exynos or Snapdragon?

Do you use masked materials ?

Which specific Unity version are you using (i.e. is it a patch release) and what Oculus Utilities? Can you provide the logcat file from the phone and Unity output_log? Maybe there is some clue in there.

You still didn't specify what SoC your phone has, Snapdragon or Exynos.

Do you use masked materials ? (alphatest)

Well, different phones have different SoC and thus drivers. Could be an issue with GPU drivers specific to S7 Snapdragon SoC. 

There was another bug report related to UE4. Same kind of phone and same kind of  crash. I don't know why Oculus hasn't investigated it yet (it's been a while since it was reported originally)

Note 4 is Snapdragon as I recall.

I am not sure why this issue hasn't been fixed yet. Maybe because Samsung sees Gear VR as movies/pics device and not really anything else (and movies don't crash).

You might want to make test case .apk and send it to @vrdaveb

> unity5.3.4f1,and oculus version is OculusUtilities_0_1_3_0_beta

Unity 5.3.4f1 is known to have a crash on some devices due to its use of VRAPI 0.6. It also has a crash on other devices due to its GL context handling. Please update to 5.3.5p2 or later.

> Note 4 is Snapdragon as I recall

There are Snapdragon (Adreno 420) and Exynos (Mali T760) Note 4 versions. Both of them are pretty old and will not be supported for much longer, especially when using KitKat.

> Samsung sees Gear VR as movies/pics device and not really anything else

Movies and photos are important use cases for Gear VR, but there are a large number of high-quality apps that do other things.

That is a separate issue. Epic has been investigating it for some time. I ping them about it regularly and will update you when they get traction on it.
