My iPhone 6S Plus was crashing and restarting about 10 times a day. I would be texting, surfing the web or just waking up the phone and sometimes it just restarts. The circle icon comes on and the phone restarts rather quickly. I thought the phone was busted so I went to the apple store and got a brand new iphone replacement. I connected it to my computer synced everything up from my old phone and now the brand new iPhone is crashing and doing the same thing. So I assume it some corrupt software. I am not sure what I did, I deleted a bunch of stuff and then it hasn't done it again. Now fast forward to my Iphone 7. Before getting the new 7 I backed up my 6S to my comp. Now after transferring everything over to my new iphone 7, its now crashing and restarting. I don't know remember what I did to fix the previous problem? Any ideas?
