iPhone 3GS ringer switch going back and forth on its own?
The ringer/vibrate switch on my girlfriend's iPhone 3GS keeps going back and forth on its own.
The phone will just sit there and frequently switch between modes without being touched. Oddly enough, the physical toggle stays right where it is so we don't think it's a loose switch.
It's forced her to turn the volume off entirely through the Settings. Because the vibrate and screen keep going off, it's killing her battery life, too.
The phone has never been opened or subjected to impact damage, so we can't figure out what's going on.
Is this a good question?
