So far I just know that sony ericsson xperia arc s can play files of 720p at its maximum. But yesterday one of my friend said that I tried to play 1080p video file and guess what, he successfully played it. I was quite shocked and surprised and I did not believe him till the end. But later on he literally showed me his mobile phone and played a video file of 1080p resolution in his player. Now I am totally confused, how could this be possible if itís been officially mentioned that arc s mobile phone can support only video file at the maximum range of 720p. Is there anyone who tried the same and got the positive result?
