i9100 and i9105 lcd difference
i'll clear this issue a bit:
the actual lcd is the same BUT...
the flat of the buttom keys for menu, back and home - it different the connector does not fit
if you buy just the lcd and put it in the old frame with this flat - it'll be fine,
but if you buy a full assembly - it wont fit.
and there is a compatibility issue with the touch sensor, there are a few revisions to the screen, the revision number is written on the back near the connector, the early ones only work good on the i9100, they will misread the touch input on the i9105 thinking it's a bit lower then the actual touch happening
the later revisions work on good BOTH models, i do lcd refub and keep a list of the revisions testing them on both models,
in the near future i will compile it and post so that it's clear which how exactly to tell if a specific screen work or not.
hope this helps.
