There are 2 sizes. 28mm and 26mm. If the number on the ribbon ends in 05 it's 28mm. If it ends in 06 it's 26mm. Hope this helps. It did when I fixed mine. Now if I can find a good rear housing cover for it I'll be set. Good luck.
The double ribbon cable of the digitizer. Is it 28mm or 26mm. I've seen both for sale. I need to buy one and don't want the wrong one.
