Hi guys, I've been using x3m player on my T9 android box for a couple of weeks and I really like it compared to perfect player which I was using and was having audio problems with ( no volume on most VOD's). Anyway, I've sat down to watch it tonight and there's a white square approx. 10mm in size suddenly appeared in the top right corner of the screen, I don't k how if the kids have been playing around with it (nobody will admit to it!!) . Does anyone know what it is and how to get rid? Thanks.
