Hi!
Trying to help a participant from another forum, I think I've solved the "mystery" of the screens for the S2 that work, or not, in our S2 Plus.
He bought it to mount it gave the error offset in the touch and then put a picture of the flex of your screen to display reference codes, if anyone could help.
First, reported that the code reference would have to look it is not the LCD but the Touch, located in the lateral flex with the ATMEL chip and connected to the main flex through the CN3 connector, and that it shows TSP AMS427GL03 rev1.1, and also the ATMEL chip was MTX224
I dismounted my i9105P and I found the following: In mine, what little you can see through the holes of the mobile chassis, the chip is ATMEL MXT224E!
But I also have another disassembled i9100 display, on which the Tactile has the reference code AMS427GL13 TSP REV0.0, date 2011.04.05 ... and the chip is, again, the ATMEL MXT224E! And besides, I have two others that are already mounted on chassis, also with the chip MTX224E (What a coincidence, with no MTX224). Well I have tested all and Tactile of ALL, works well.
Another thing that I've noticed! ALL 224E chips have a large G printed over in white colour, while the 224 chips that I have broken screens do not anything printed over.
Will Samsung scored screens that initially served only for S2 i9100G but, now, are also operating in the i9105?
