Mine was purchased at a local AT&T store in the USA. It is the SGH-I717 and is mfg. in Korea.

I've had it for a little over a week now and when I play Netflix or You Tube (HQ streams) of B&W movies with dark scenes and/or fade ins/outs, the picture becomes pixelated and blocky. As if there was no gray scale, just blotchy blobs. My older Captivate plays these scenes perfectly.

As a new member, I can't post a link to a You Tube video comparison that I made to show the differences between my Samsung Captivate and my Note, but you can find it by searching for: "Samsung Galaxy Note BLACK CRUSH Demo".

I have tried to post about this issue to the AT&T reviews forum several times, but they will not accept the post. I wonder why?..... [NOT]

There is a test pattern out there that you can easily find (again, I can't include a link yet) which has a 22 rectangular block grid of different gray scale gradations, from white to black. Does your Note reproduce this test correctly (a gradual darkening of all the blocks until the numbers from 7 to 0 are difficult to see), or does it look like mine (all the numbers from 21 to 1 are visible, and 0 is completely black.

I LOVE this phone but for this one irritating problem. I truly hope that a fix is forthcoming from Samsung.
