I Had a 6 which worked fine, switched carriers and now have a 6s that is a piece of garbage. my 6 had 2 apps, phone and messaging. 6s keeps popping up something about a update for Japanese transit ???? something called Siri won't shut up, and my slide screen is gone. I have no clue what iCloud, iTunes, or iBooks is ? theres a blank white face next to my contacts? Can't delete it? The battery goes dead is less than 1hour. My weather is setup for Santa Clara California and I'm in Pennsylvania. And it keeps asking fora Apple ID password, which I don't have. I don't play any games, listen to music, take pictures or anything else. How do I delete everything except the phone app?
