I just got an S4 after being an iPhone user since the beginning. I have transferred all of my iPhone pics and videos to the Micro SD card that I have in my S4 but the videos will not play. They are obviously in apples quicktime format, .MOV so how can I get these videos to play on my S4? Is there a video app or plugin that I can download that will play the videos? If not, what can I do? Is reformatting each individual video the only option I have? And what format would I have to convert the video to in order to play on my S4 using full screen .. thanks
