Hi, suddenly my phone is not playing any videos. It corrupted a whole SD card and had to change it for a new one. I thought that was the problem why the device wouldn't play any videos. Nothing in the gallery would actually load. I performed a hard reset, and inserted a working new SD card. But still, not gallery videos, instagram or youtube videos will play. Audio does play but screen stays blacked out. So streaming if streaming videos won't play as well, it is not an SD card problem. Any ideas?
