(I was trying to cross link this thread with another one in this forum to bring them all together, but I'm not allowed to link.
It's "Nexus 4 screen problems please help!!!!!!")
Looks like the same/similar problems.
If this is an update bug it'd be nice to squash it before everyone gets updated?
Alternatively, maybe it's missing RF tape on the digitizer chip attached to the ribbon? I'm going to call and ask tomorrow to see if he knows if his replacement screens come with the RF tape, or if it was omitted. I know if it was there's nothing in there as I have my old screen and the tape is still attached.
Or maybe something in replacement Digitizers/LCDs, although my repair guy said he was using LG parts?
OR, maybe, there's something to do with the encryption on the tiny little part that's just below the digitizer/lcd connectors on the mainboard that is easily damaged when servicing? I know mine was slightly bent because someone pryed on it.
