iPhone 6 won't save or delete photos
Hi!
For the past 12 hours my iPhone 6 has refused to save or delete photos.
Saving as in save to camera roll when I take a photo, take a screenshot or try to download one from safari.
Deleting as in delete from camera roll or when imported to Photos and then deleted.
I've tried restarting the phone, but nothing has changed. I have about 5000 photos on the phone, but there is still 19GB of space on it (I have the 64GB-version), so available space is not the issue here.
I was in Japan this past weekend and used a prepaid simcard when there. The issue appeared right after I switched back to my regular sim. Is it possible that it is somehow connected to this?
Help?
iPhone 6, iOS 9.1
