Latest Surface Pro firmware update fixes jittery Surface Pen issue

Over the past few weeks, many Surface Pro users have complained about issues with their Surface Pen. Well, Microsoft has finally listened and yesterday released a new firmware update to address jittery Surface Pen problems (via Windows Central.)

As noted over on the Microsoft Answers forum, many have noticed Surface Pen’s inking lines would break up whenever a user has their hand on the screen when drawing. “If I begin a stroke with my hand already resting on the screen, there is a significant offset of the pen line to the actual tip position. This makes hand-writing nigh impossible,” wrote one user.

Well, yesterday’s firmware update fixes both this problem and adds in some security patches too. As noted in the changelog:

  • Marvell AVASTAR Bluetooth Radio Adapter – Bluetooth: 15.68.9125.57 improves system security.
  • Marvell AVASTAR Wireless-AC Network Controller – Network adapters
    15.68.9125.57 improves system security.
  • Surface Integration Service Device – System devices 4.18.136.0 improves system stability.
  • Surface Touch Servicing ML – System devices
    1.16.139.0 improves pen and touch performance.
  • Surface Touch – Firmware 429.0.1.10 improves pen and touch performance.
  • Surface UEFI – Firmware 234.2291.769.0 improves driver installation servicing.

As always, this latest patch will be showing up in Windows Update, so be sure to install if you’ve been having issues with your Surface Pen. Once you’ve updated, let us know in the comments below if you’re still having problems with Surface Pen.
