I recently managed to install the latest Mokee rom on my phone, and I must say I am very pleased with it, except for this issues I'm now stuck with: apparently I am completely unable to playback any video on my phone. :(
At first I tried recording some videos: when I tried to watch them back to check the quality, a popup told me it was unable to play them. I thought that maybe they were not being saved correctly, so I tried to watch them on my pc, but to my surprised they played fine! I tried the opposite process too, playing on the phone videos coming form the pc, and the result was the same disappointing failure in reproducing it. :eek:
Then I thought it could be some problem with the default player, so I downloaded VLC from the play store and gave it a go. What happened next surprised me even more, as it would play the first couple of seconds of video before crashing miserably giving an error report log.
I now suspect it has got something to do with the rom itself.
Have you guys got any ideas?
