Not a big issue for u, it affects me and I want to know how to fix it
I do not think it is a rom issue as my proximity sensor works fine with this rom. That is when I make a call and place the phone next to my head the screen goes blank and the on...
yes N7000XXLT3 is the modem associated with the LT9 ROM in both stock and sweet.
With the LT9 sweetrom v10 I have used the XXLT3 and the XXLT4 of these 2 I found that the XXLT3 gave me better data rate, comparing them in the same locations. Phone and messaging much the same on both.
