[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] Rav3:
Hi All,

I've had the Note for about a week, exceptional device in most aspects, however the biggest issue to date appears to be this problem with shadows/details in dark scenes and the blocky artefacts.

Doing some testing I can confirm this is not a problem with bit rates or video quality, I have tested with a full 1080p MKV with 20MB bit rate and it still has the same problem.

As a test, I've attached a small sample of the film, please could other fellow owners test and report back, especially the ones that have said they do not have a problem with high bit rate content, this sample is 13 Mbps bit rate. Dice Player is recommended for viewing this clip, study the black areas on the top left hand side and the far right hand side, the appalling dark scenes will be apparent, here is the MediaInfo information for the video:

Are there any experts on the forum that would be able to deduce the source of the problem given the above information. This is a very serious issue and needs to be reported to Samsung ASAP, what would be the best route to bring this to Samsung's attention?

Thanks
