I've had my M9 Pro for about a month. A small black dot has appeared under the screen protector. I ran a dead pixel test and the same dot appears in all colors, except black or course. I took "screenshots" with the background in various colors and emailed them. When I viewed them on my laptop the dot did not appear. If I take pictures of the screen with my phone it clearly does. Does not seeing the dot in the emailed screenshots indicate anything as to whether it is actually a dead pixel or not?

It shows a small black dot here slightly to the left of the middle. I suspect that the resolution of your laptop is not set high enough to see the black dot and as all the other pixels are blue, your laptop doesn't show the black one. I think you should see it once you zoom in. So it seems like a "normal" dead pixel to me...

Oops. Those were pictures from my phone. The screenshots are below.

You are not supposed to see a dead pixel on the screenshot, the screenshot is just the image which is sent by the CPU/GPU to your tablet display, not the image which is actually shown. :)

Got it. Thanks. Just wanted to be sure before I contacted the seller.

I'm afraid although its only a month old they will say I would need to pay shipping both ways to China and wait many weeks if anything would be done at all.
