Recently when I tried to view any new pictures and videos I've taken they don't work. Both pictures and videos appear with a little grey box and whenever I try to view a video it says "Sorry, this video cannot be played". This only started happening since 2 weeks ago and I can see all my old photos and videos but not the new ones. I don't know if this helps but my phone was working perfectly then I recorded a video and this began to happen. The new pictures and videos also don't work when I transfer them to my computer. Anyone know how to fix this?
