Hello,
So, I have texted you MS Support team a while back about the touch screen becomes unresponsive all of a sudden. My SP7 was brand new. All recommendations given by them were followed and were not successful in resolving the issue. However, I noticed when I used my stylus the screen touch becomes unresponsive. When I don’t use the stylus, the issue never happen. The stylus I used to use was the Slim Pen. So, I bought the surface pen and the device is working properly and the issue doesn’t happen anymore.
I thought I would share this so you could spread the word or test if this has only happened to me or other customers have faced the same issue.
Best,
