iphone 6 touch screen freeze..but...

...but unfreeze if detach front camera flat cable.
i explain...
iphone 6 sometimes works,then freeze or start commands itself,
changed display set and all same,
i try whit another one and works good,so i fix home key,screws,front cam whit audio and sensors.
i try and...touch freezed ,
make me crazy,
i try to use old display and it works
so step by step i understand the touch screen works only if the front camera flat is detached from board
changed flat camera and is the same,phone freeze and cant use touch screen,
tryed to isolate contacts,components and nothing.
what i can do for solve?
no teardown,no water,all original parts.

the touch screen works again after remove the front camera flat only if shut off the screen or disconnect and reconnect battery.

Your problem is easy with me !
your problem is (TOUCH Freeze or stuck when connecting FRONT CAM) why ? you have problem in synchronization between CUMULUS IC CHIP and proximity all this is found in these SIGNALS
so to sum up
check the following:
they are linked to PIN number 25 from J1111
then test R2405 this is very important it's responsible to SYNC between Proximity sensor which is on FRONT CAM FLEX and CUMULUS TOUCH IC

See the following photos

they must have 1.8 VOLT when testing with multi-meter !
