I have my videos backed up on PC from my previous iphone and they are in .mp4 format. But when I go to transfer them to my Turbo it says that the file may not be able to play if transferred. I transfer it anyway, hoping it would play, but when I go to play it on the phone, it doesn't work. Does it not support mp4 format? Maybe I'm doing something wrong. Do I have to drop the videos in a separate folder? Because I drop the folders in bulk with pics and videos together - pics transfer fine but not videos. If anyone could help me out in this that would be great.
