Hello, I played with several Galaxy Note in different stores. I noticed that among the videos I watched from Youtube, half of them had very poor video quality (e.g. coarse, visible squares making up the images). The staff said that it was due to the poor video quality of the original files. Given that I encountered such issues while using different units, I suspect that it might be a defective issue with the devices or with the OS. Could somebody please clarify the causes of such video issues? For those who have upgraded to the official ICS, do you encounter such issues? Thanks.
