that did not come out the way I typed it! I have a short video on my phone that I want to transfer to my computer. Every way I have tried sends the video with no sound. Only Dropbox took it, but then the 'play' arrow shows up in the middle of this very short video
No, the questions are to reduce it becoming complicated.
When you ask a very generic how to ...... question when you do not state specifically what you are trying to do, let alone whether you are even using iPhone or Android that means we either A) provide you with 17 different answers to cover all the possibilities, or ask you 2 simple questions.
Since that is apparently far to complicated then I suggest you only by an iPhone and then take it to apple store for all your questions
