I think the video quality matters the most. Of course different batch would have different outcome but what is apparent is that each and every Note has banding problem which is a known defect.

Just run calculator and its there... no denying that... but was it as bad as the one shown in XDA? I dont think so.

Today meet up with my friend and tried the Iron Man video to compare with his 7.7 but surprised myself. Can't see those blocky on my Note. I thought for a moment how it magnificently fixed itself. Went back and try again in my room but see blocky again.

The auto brightness and broad daylight could fool your eyes.

Tried Lumia first la... otherwise you see the Lumia later also cannot stim...

Anyway, as far as I can remember, the widget does not lag. However, when it was pulling updates (especially if you are using the emails with it as well), it can froze for quite long, depending on your internet speed. Once finish updating, no lag. Stop using it because of the pulling updates issue. Use Facebook apps with Gmail and Hotmail apps with better result and notifications as well.
