Ok I'm not tech savy at all. Yesterday I noticed my ringer had changed to default ringer and all the ones I had downloaded are gone. Along with music and pictures. The funny thing is everything I downloaded from Thursday to today is still on my phone. So everything before Thursday is gone. Along with that issue my battery which is extended life and usually last through several days without a charge won't charge completely or keep a charge. I tried taking memory card out and battery. I put a new battery in it and it's still doing the same thing. I can't get a charge over 30% with it plugged in for hours. I checked apps that are running an it's only basic ones no gps or wifi. Please help! My warrenty is up and I'm sure like most of you I CAN'T LIVE WITHOUT IT!!!
