[Samsung Galaxy Nexus] Formhault:
This is a very long post.

Well, next time you visit him set both phones on max brite. Install Screen Test and see how bright each color is. I know for a fact that my Galaxy Nexus's screen is a LOT brighter than the S2/Note/S3 (also set on max brite, with Standard mode).

Anyway, I compared my Galaxy Nexus to a display unit that was placed in a Vodafone store... The display unit is there since January : thus, specific burn-ins (for example, the lockscreen ring) have appeared. The gray background from the Settings menu is actual GRAY on that unit, while my phone has it purple (when the brightness is at its lowest). The whites are more white on my phone, though - they were more gray on the display unit. Overall, mine was brighter - but the display unit definetly had homogenous full whites.

Well, my screen has those, too. Especially when on low brightness - actually, as I increase the brightness, the banding goes away entirely. It's not too bad when on low brightness, but it's there...

Also, ghosting comes in. For example the app drawer icon (which is white, meaning it activates the entire sub-pixel matrix) is visible on a gray background afterwards, and goes away after a few seconds (~10 or so).

Full grays become purple when the screen is set on 0% brightness. At least on my unit... and I'm definetly not the only one.

Oh, that's right. The thing I reffer to as ghosting is the image retention you're talking about. Just so you would know :p

My phone has the best colors I've ever seen. I had the S2 before. Well, here's the thing. The colors on the S2 did not tend to go feint when you lowered the brightness - they seem to do so on the Galaxy Nexus. But put side by side to a S2, on full brite, the GN seems a LOT better.

I don't see much grainy effect. Well, it's there - when the brightness is lowest or near that point - and is especially visible on grays or whites. Also, the whites are not homogenous : purple tint to the upper-left corner, light-blue tint to the lower-right corner (but overall, it's not so bad - it's only visible when reading articles, and guess what, that's what I do).

My device is Made in China by Samsung :) . Do you think there are units manufactured in other countries, as well? I believe the ones made in Korea are for Korea only - if there are any. The S2 I had before, though, was made in Korea, as I recall (but I might just as well be wrong).

Even the iPhone is made in China. My previous Motorola ATRIX was, too. The HTC Desire, as well. But I guess each company has its own principles and its own ways to kick people in the butts when proven their QC sucks... or lacks entirely.

I don't think QC lacks entirely, though. I mean... at least there aren't problems with other hardware than the screen. If QC were to suck that much, I believe we would have had falling-apart cameras or such :D

Of course they can't duplicate your issues... Most people don't actually look that carefully at the phone. When they get a phone into service, they look at it for a few seconds, and if their eyes are closed, of course they consider you a retard and... oh well, I guess you know how Customer Support goes from there :rolleyes: (as in bad). I know I experienced that... with a ****ty Motorola Z8 which wasn't taking charge anymore - they first replaced the USB port, then the battery, THEN the flex cable (which I told them to look at in the first place). Oh well...

Some people intentionally say they can't replicate the issue you're having just so they get out of paperwork or the trouble/effort to replace your device... Others do that just because the CEO tells them so (and that's the case here, I believe). I doubt Samsung engineers are that retarded/blind :rolleyes: .

That's why I always call back the services I call to and put me on hold, from another phone, and swear at them as hard as I can. They being told not to help customers... I might be okay with that (like 5%), but they putting me on hold for such a long time or never calling back... I'd slit their throats for that.
