Any solution for that?
I am using CloudyG3 1.3 ROM
Always make a nandroid backup through recovery.
I would suggest you use either Dorimanx (http://forum.xda-developers.com/show....php?t=2725023) or RenderKernel (http://forum.xda-developers.com/lg-g...-roms-t2803929).
Dorimanx is for Stock Rom while use RenderKernel if you want to go to AOSP based roms.
Then I'm guessing the problem is a hardware one. Have you ever dropped or bumped your phone? Even if you haven't have how long has this problem been occurring? Ever since you bought the phone or recently. This is because even though it could be a software problem, if you flashed the roms and kernels correctly, there shouldn't be any nfc issues in all of them. So in any case, I suggest you try to get the phone replaced or fixed.
