Title:

Why does my touchscreen only work when touching the case?

Text:

I recently picked up a Surface Pro 4, and I love almost everything about it. There is one behavior, however, that puzzles me. It seems that, when I am holding the device with my hands, the touchscreen is perfectly responsive. When I touch something, even lightly, it recognizes my finger... no issues here.

The issue arises when I am not touching the back of the tablet. Let's say I have it propped up on its kickstand, or resting on a table. If I don't touch it for 30 or so seconds, then try to use the touchscreen, it can become very unresponsive. Basically, if I have no point of contact with the device other than with the finger I am using to touch it, it have to firmly press, or hold, to get the screen to see my finger.

This behavior can be demonstrated in OneNote with the finger-writing enabled. I put one finger on the side of the surface, or the back, or anywhere that is magnesium, and I can draw hundreds of lines and it will pick up all of them, with their correct lengths. If I don't touch the side, about 50% of the lines will show up (doesn't recognize the other 50%?) and the will often begin a few cm away from where I started, but end in the right place. It's almost as if once it recognizes my finger, I can keep a continuous line going, but it has trouble recognizing it.

The digitizer works flawlessly at all times.

Anyways, just wondering if anyone has experienced anything similar with maybe a surface, or just a tablet in general. It's such a new device that not many issues have come up when I try to look into it elsewhere. I have worked on so many iPads, and I've never seen anything similar to this.

Thanks
