iPhone 6s keeps restarting and looping
I updated my iPhone 6s from iOS 11.0.3 to 11.1.1 and ever since my phone will not last two days before it restarts itself and then go on a loop on restart. I tried force restart and recovery mode then update but the only thing that would bring the phone back is through a restore then it will work. After that I restore my data of the past two days and then wait for another two days when my phone will go on the same problem of looping all of a sudden (sometimes while it is idle in my jeans pants).
Please any one help me with this.
iPhone 6s, iOS 11.1, iOS 11.1.1
