So since the update to jelly bean, my phone has done something odd: the ringtones will at times change itself. I assign a certain ringtone to everybody but every month, at least 3-5 times a month, it would be a generic ringtone. Sooo....does this sound familiar to anybody? Also, as of recent, within the last month, 2 things happen: I would charge my phone and it would stay at 90% when in fact it should be saying 100%, then the battery has been draining faster than usual. Nothing new or different has been done to the phone, so nothing makes sense. Anybody have any ideas? To clarify, the settings have been the same for a while, but for some reason the battery will drain to 60% in 3 hours even though the settings were the same just as they were last month and it has been 3 weeks this has been happening.
