I have a 1520 with a 64gb memory card. For some reason, when I take photos and videos...sometimes they disappear....randomly.....I also get black screens where the photo and video should appear under camera roll. Does anyone else have this problem?
While Its Microsoft's fault for not offering enough information about their requirements, nor do they offer warnings about slow memory cards in their OS (which would've been damn easy to program) your card my sir is a slow card (read write speed), what you need is a Class 10 card (pick your brand as long as it fits that specification (Its written somewhere on the boxes).
Sorry for the lost memories I lost a recorded guitar night with my friends because of that too.
