I recently bought a sgs3 and I keep noticing that apps I've downloaded (facebook/messenger, etc) keep getting deleted and I have to re install them. Can you tell me why this is happening? After having an iPhone for years I decided to go with a change and so far I'm loving this phone. But if this keeps happening I'm going to take my phone back and get the iPhone 5. Any help or suggestions is appreciated. Thanks so much!!!!
