A couple of days ago one of our docked Surface Pro 4 (SP4) units started to experience what looked like an ongoing touch in the middle between the two screens near the bottom.
A reach over to the SP4 and a touch to figure out where the phantom touches were happening brought about the discovery that it was near the bottom righthand corner of the touch screen.
Weird.
Okay, so pull it off the dock, give it a good screen cleaning, and for good measure blow it out since it's been sitting there for a while.
It seemed okay but the problem came back.
A reboot would not fix it either.
So, in to the Microsoft Store we went today. The tech took it into the back for a few minutes then came back and said it's good to go.
What was done? They have a calibration tool there at the store to recalibrate the touch screen.
Since that was done the SP4 has been behaving. We'll see, but let's hope it's all good.
As it turns out, the task run by the Microsoft Tech is in the above KB article.
So, if experiencing phantom touches download and run the calibration tool found in that article.
UPDATE 2018-09-10: They came back. :(
As an FYI, this time around instead of hugging one side of the screen we had a line of touches running across the screen.
So, instead of heading back to the store we ran through the hotfix e-mail process and ran the utility.
The phantom touches disappeared again. We'll see for how long.
