This glitch is not Minecraft specific, but it also is a problem with the entire XBOX app on Android devices in general. I am not sure if this is a specific problem with my phone, however reviews on the Google Play Store (Link posted as of August 30, 2016) seem to show that I am not the only one experiencing this problem. This glitch essentially makes it impossible to sign into XBOX Live, as when you sign in it will immediately redirect you back to the sign in screen. Or in the case of Minecraft: Pocket Edition, it will simply take you back to the home message without any error codes or messages to hint at what the problem is.
