I haven't experienced any reboot issues. The only thing I have noticed so far is something weird with Spotify and the lock screen music controls. I stream music from Spotify through my car's bluetooth system. While the music is playing, the lock screen displays the normal music controls. After I turn the car off and the streaming is paused on the phone, the lock screen music controls try to take up the whole middle of the lock screen and appears underneath the other controls. I am still able to unlock the phone, but it looks weird. Not sure if it occurs with other music apps.
