@slackmoehrle yeap that would be great. You can maybe understand the problem when you see it on the device…
You can download the .apk via https://www.dropbox.com/s/bujj51c4e27w29c/PierRun-debug.apk?dl=0
As I said before, it works great on Android 5.x. Only Android 6.0 users complained about the problem. Normally on my Android 5.0 device, fps value is something between 50-60. On Android 6.0, 30-40. When they mute the game, fps is between 50-60.
