Yes you are right, they are very close, the processors also seem to be nearly the same too just slightly different snapdragon variants, the only thing really different is the rear speaker placement.

Do you guys think that this is a problem within the electronics of the phones using the 1.5Ghz processors, or just due to a problem in the screen manufacturing process for the larger screens?

If anyone is interested I know someone involved in a Houston area hacker space who can put up a bounty on finding the problem in the g2s screen. They have many hardware hackers / engineers there and every diagnostic tool you can think of from P.C. board etching systems to data loggers, oscilloscopes, frequency / pattern generators to microscopes . . . It may be something as simple as lack of current.
I think we've had enough of the bounties lol, what happened to "doing it for the love of it"?......plus supercurio and another has already touched up on the issue.

I'm just sayin!

Are they not software hackers only? I was talking about hardware only guys.

Apparently some models suffer and some don't. It is not isolated to a particular color. Are you sure you followed Cheema's testing direction properly?

Are you talking about the vertical lines issue or blobs?

Did you use a grey background?

What is your phone production date?

The guys in the galleria mall T-mobile corporate store did say that there were some flawless displays in some models.

In some cases the white ones have been the worst.

If the hardware guys want to do it without a bounty then i'm all for it, but raising a bounty just to find out if the problem is hardware or not doesn't make sense to me, especially when we have supercurio working on a workaround to the issues. Basically supercurio already stated that the lines and blobs are a hardware issue. Also there's another thread stating that the blobs are what you call "Mura" which is a hardware issue. The bounty for supercurio made sense because at least, he can possibly develop a software fix to mask the problem. Why should we give money to a group that will basically prove or tell us what's already been said?

I'm just sayin!

I only did the blobs test,and of course they are some blops and vertical lines like all Amoled screens,but the color reproduction is very good,and they are almost unnotice (yeah yeah forgot the word).I dont know the production date.
