Just noticed this yesterday, when I take my phone off vibrate (using the side button) my phone doesn't always return to the normal ringing function. I have to reboot the phone in order for it get out of the vibrate mode. I did update the new 6.1 the other day but not sure if that has anything to do with it. Anyone else have problems with their phone staying in vibrate mode? I guess my other question is would I be stuck with a remanufactured phone if I needed to return this? Thanks for any help you can give me.
