Ok let me add this
I work for a repair shop and replaced my iPhone 5 screen 2 weeks ago already on 9.2 and it worked great for couple weeks then the touch started to move by itself and would take 10 secs to unlock so I couldn't answer calls
I cleaned and checked the cable was connected ok but nothing helped untill I removed the screen covered the touch connector with flux and did a solder reflow plus clean again
Now the touch works fine when using the phone untill it's left locked for more then 5mins then the swipe to unlock will fail the 1st try 2 sec delay but before repair it would take 10 secs to work so it's better and shows no fault in normal use
It's odd how a screen can work fine untill locked and not be software maybe it's both I did try the 9.2.1 beta it didn't help
