Well.. Turning off the double-tap worked... Not one single ghost touch since... The sensitivity is still set to night.
No need for exchange or anything... Phone perfect now.
I went thru the same thing, testing different combinations of settings
(OFF / ON) to resolve the problem, with some temporary success.
Ultimately, I waited too long & my warranty expired, thus I had to pay for the new digitizer. It fixed the issue (@ least so far) & I'm chalking this up to
lessons learned & hope it continues to work.
For those with success, hope it holds ... I think there were
possibly several issues lumped together, some software conflicts, some hardware
(digitizer / touch screen). For the brave, attempt some graphics intensive task (Angry Birds, HD video, etc) on the device, that was always my
waterloo.
BTW- current settings:
- Haptic feedback on Nav keys = ON
- Double tap to wake = OFF,
never really liked that
- Hey Cortana = trained & ON
- Touch sensitivity = Normal
- Glance screen = ON
(peek) with Weather displayed
- Vibrate = ON,
that's attached ?? to the digitizer back
