Sounds like she may have spilled something on it and it has dried down inside. Could have been a pop as they do become sticky after they dry!! My Mom did this to her phone one time and it messed it up!!

Yes, we never know what these kids are up to when they are out of our sight. Good for you for being concerned.

Good luck to you and by the way, I won't tell hubby about your's being faster. Hee Hee!!
