Surface Pro 7 pen pressure issues with palm rejection

Anonymous

Pen works fine when only the pen is making contact with the screen. However, when my palm is resting on the screen, the pressure detection of the pen becomes extremely inaccurate. As soon as skin (palm, fingers, etc) makes contact with the screen, the pressure curve of the pen becomes a staircase, as if the pen could only detect 5-20 levels of pressure, instead of 4096 like it's supposed to. Here's a screenshot from the Surface app:![](https://learn-attachment.microsoft.com/api/attachments/cdc3b0c5-bfcc-4409-b0a1-318885287f48?platform=QnAAnd here is how it looks like when drawing:

Is this normal? How can I fix it?

Device: Surface Pro 7 Model 1866 i5 (8GB RAM, 128GB SSD)

OS: Windows 10 Home Version 1903 build 18362.449 (edit: I've since updated to 1909 build 18363.628, issue persists)

Pen: Microsoft Surface Pen Model 1776 (Burgundy) 

I have:

  • paired my pen
  • unpaired and repaired the pen via Bluetooth options
  • rebooted the Surface Pro
  • soft reset the Surface Pro (volume+ and power buttons down for 15 seconds)
  • removed and reinserted the battery into the pen (only way I could think of turning it off and on again)
  • checked Windows Updates
  • checked for app updates via Windows Store
  • run the Surface Diagnostic Toolkit, no problems detected
  • tried with and without Settings → Devices → Pen & Windows Ink → Ignore touch input when I'm using my pen
  • set the correct hand I'm using from pen settings
  • tried in multiple different apps, including Surface app, Adobe Photoshop, Krita, Sketchable, Autodesk SketchBook and others — same problem everywhere
  • tried calibrating the pen (search "calibrate" from start menu and choose pen calibration), a dialog opens after choosing "Calibrate..." → "Pen input", asks for permission, and just makes a sound and closes after I grant permission, so I'm not sure if it's not working correctly, but nothing changed either way — tried to do this multiple times, rebooting in between, but doesn't seem to do anything

    Thanks for your reply! I ran the Diagnostic Tool again now just to be sure. Just like before, it didn't find anything.

    From Device Manager, I uninstalled almost all HID devices just to be sure, not just ones that said touch/pen/ink. It started adding them back after I had uninstalled almost everything. I rebooted. The problem still persists. 

    Anything else I could try?

    Hello ,

    Thank you for reaching out Microsoft Community. Can you try the methods below and see if there are changes.

    **Method 1:**Run Windows Updates or SDT, and test on known app.

    • Run Surface DiagnosticToolkit. It is a self-healing tool which looks for potential issues and fixes them, as well as ensures your device is completely up to date.

    Method 2: Uninstall all Surface pen driver and touch drivers (including hidden drivers/devices) :

    • Go to Device manager
    • in device manager, click on Human Interface Devices
    • Make sure you show all hidden devices under HID

    Uninstall all drivers and devices that related to touch and pen like including those that are hidden; HID-compliant touchscreen HID compliant Pen, Intel Precise touch driver, Surface Pen settings and restart your Surface to reinstall the drivers automatically with the updated one.

    Please keep us posted.

    Regards,
