Runtime permission dialog not pop up in Galaxy S7 Edge version

In AndroidManifest.xml, set targetSdkVersion="23", but it stuck at black screen when I launch the app, and when I take off the phone its pop up the normal run time permission dialog.
I think probably there is some issue with Android 6.0 (https://developer.android.com/training/permissions/requesting.html) with oculus sdk.

Currently what I can do is just set targetSdkVersion="22" to skip the runtime permission to fix this, any suggestions for a long term fix?

Thanks in advance!
