    I am using the official Google Cardboard SDK and using the demo scene. When I run it on my phone I start out with around 30fps. Everything runs fine at the beginning. However if I tap the screen several times, the frame rate with continue to go down until I stop tapping then The frame rate will never return to 30fps. Does any one else have this issue? I am running on a Galaxy S4 if that helps any. This issue makes it impossible to develop unless I use no touch input at all(which I would prefer not to do).

    Can you check adb logcat to see if any error messages are being thrown? Also, which versions are you using of Unity, Android, and the Cardboard SDK?

    My Unity version is 5.1.1f1, I have the newest version of Cardboard SDK, and My phone version is 4.4.4 if thats what you mean by android version. Also I don't know how to use logcat with unity.

    Also this issue only happens when VR Mode is enabled. If I disable it after I tap the screen a lot it will just go to 60fps, but when then enable VR Mode it will go back to bad frame rate.

    We have heard a few reports of latent input when VR is enabled but not in use. We're investigating and will let you know when we have a resolution.
