Video playback / Videos stored on iPhone 6 not playing or working - thumbnail / preview is white / grey, and play button does not work
iPhone 6. running the latest iOS 8.2 (as at 8 april 2015). 64gb.
I am not sure when this problem began, but all of my videos (but one) that are saved in my iPhone's "Videos" album (within Photos) will not play, and are displaying a blank white / grey preview thumbnail.. When you click the video, the 'play' button does nothing. You can see the date & time the video was taken, but nothing else. I tried using the iMovie app to try access the videos - and they still appear as "grey / white" and cannot be played.
Here's a preview of how the album view, the video view, and the iMovie view look...
Many of these videos were saved direct to my Camera roll from my Snapchat app (by downloading my own daily "stories"), and the rest were filmed and stored using the iPhone camera app..
I do recall them working in February 2015, but have no idea what caused them to stop playing and what date..
I have tried resetting the phone and googling for answers with no luck.
Please help!... I really want my videos back 😟
iPhone 6, iOS 8.2, null
