I will probably need to post to the Apple site, but something weird happened to my phone last night. Sometime during the night with the phone unused and without any automatic updates installed, the battery started to run down rapidly and the phone lost the ability to download/show many photos across a wide variety of apps, including Instagram, Facebook, Whatsapp, etc., but while some photos will show up, others just have the refresh arrow. The behavior is the same on/off Wifi.

I've rebooted the normal way as well as a hard restart multiple times, but there is no change.

Has anyone experienced this before? I really want to avoid doing a backup then reset and restore if possible.
