[oscarveli21]

I have a few videos that I took using the z3 and are saved in the internal memory,some won't play it says video cant be played and it plays in the preview before I push the play button,its only on a few videos
I'm also having problems downloading photos from the internet,it says download fail when before I wouldnt have any issues

Have you tried copying those videos over to your computer via USB and seeing if they play there? If they don't, then the video file got corrupted somehow.

Do the downloads fail on both wi-fi and mobile data?
