My Iphone 7 keeps shutting down and asking for my passcode

[Anonymous]

This morning I have opened my iphone 7 to use, as I keep my phone locked with a passcode. after about 3 minutes it shuts down and goes back to the passcode page. when I put in my passcode it has closed the app I was working on and gone back to the home page. 

I has been doing this now for 2 hours!

Any tips

Nothing has happened to it in the night? and it was working correctly yesterday.

many thanks Trudy

Ain't that the truth!

I’ve had the same problem with my iPhone.  Phone worked fine the day before and keeps shutting down in the middle of a process and asking for my passcode. Annoying opening on the home screen.  I have changed the auto locking time to 5 mins and it still shuts down, have also tried rebooting it but again no fix.  Have you found a solution?

Apparently you need to apply the latest firmware update which is 11.2

I have installed 11.2 and it has made no difference.

Have you followed these instructions after installation? https://support.apple.com/en-us/HT208332

@Anonymous The instructions were in the linked thread if already done 11.2 it may require more work as before upgrade you had to turn off the notifications !

Yes - I have follwed the instructions and it hasn't fixed the issue.

Does this only relate to iPhone 7? I was planning to go to my local Apple store and buy an 8 tomorrow.

We had one person with a 6s but all the rest have been 7's.
It's not affecting everyone though.
