I am on my 3rd iPhone 6 plus 128gb model. The phone has been working fine for the past few months. Today it started crashing like crazy. No apps were installed recently, no jailbreaking, no 3rd party apps (if that is even possible). I am at my wits end. I tried setting them us a fresh install and it continues to do so. I know 128gb are the only ones to have this issue. Has anyone with this storage size not have this issue? My phone is restarting during calls, when just sitting idle. I have the latest software version. I am at my wits end and not sure what I can possibly do. Any thoughts? My car is in the shop and will not be able to go to any Apple store until I know when I will get it back.
