Top of touch screen is misaligned.

[Guest Evi1d33d]

I draw a straight line down the screen with a ruler and as you can see on the top part is off and it gradually gets better. I ran the align screen program but stuck in a loop... So do I have to get another digitizer or is there a way I can manually calibrate it? I was thinking about messing with the calibrationdata entry in the registry.

I'm using i910 with DC22 but it's been doing since FC03.

have you tried to align the screen, BUT try to compensate the misalignment?

like this: or like this

hit a bit to the left to compensate... one of the above should work!

maybe you can just improve a little bit with this workaround, and avoid buying a new digitizer

If you still stuck in the loop, edit in registry... seen the magic numbers in this forum before, but can't find it now

Thanks for the tip, but I just can't get out of the loop :huh:

I already checked the registry and it's already using the 'magic numbers'. I think the numbers are center and corner coordinates, I'll probably just mess around with the numbers and see what happen.

HKEY_LOCAL_MACHINE\Hardware\Devicemap\Touch\CalibrationData

”519,503 177,881 182,129 847,127 849,872”

these values right? they look like {center, top-left, bottom-left, bottom-right, top-right}

the idea is the same, try to move one of the crosses a bit to the left.

the corresponding numbers of the images i posted should be something like:

”519,503 177,881 182,129 847,127 749,872”

and

”519,503 177,881 182,129 747,127 849,872”

Thanks for the help but I think the touch screen is gone. The top left corner is completely messed up and I don't think the cablibrationdata will take negative numbers lol. I'll just get a new digitizer then, they are like $4.

Hi, you will definitely need to replace the digitizer. I had the same problem with my omnia after 1.5 years of usage... luckily i bought it with a 2 years warranty so i sent it back to the store and they gave me a brand new omnia since they didn't have any digitizer to replace on my phone.
