Mean like you're downloading a video from YouTube or something or off the internet or a video you took with your phone I'm not sure I've never had that problem before and I'm only used to androids I've had the Droid Maxx and now I just got the Droid Maxx turbo so I'm not used to the phone you have your best bet is to call tech support call your carrier they should have tech support if not just google your phone the brand of your phone I mean and get the phone number to the company and then I'll definitely have tech support. I hope that will help you out have a good one
