Fix OneNote Stylus Drawing Only Straight Lines on OnePlus Pad
Question details
The user needs to fix a stylus malfunction in OneNote where it restricts drawing to straight lines instead of allowing freeform strokes.
- Product
- Microsoft OneNote
- Device & OS
- Android (OnePlus Pad)
- Scenario
- Attempting to draw or write with a stylus in the OneNote app while the on-screen keyboard is open or a physical keyboard cover is connected.
- Observed behavior
- The stylus fails to draw normal handwriting or curves, only drawing straight lines.
Before proceeding, check if the issue persists when the keyboard cover is physically disconnected from your OnePlus Pad, and ensure your OneNote app is fully updated from the Google Play Store.
Report the Issue to Microsoft 365 Support
Since this is a known compatibility glitch between the tablet's keyboard environment and OneNote, escalating to Microsoft Support is the most effective path to an official patch.
Because the root cause heavily depends on the specific Android version, OnePlus hardware, and OneNote build, community workarounds may be temporary. The Microsoft team needs diagnostic data from affected environments to release a permanent fix.
Note down your specific OnePlus Pad model, Android OS version, and the current version of your OneNote app.
If you use a Microsoft 365 Business or Education account, reach out to your organization's IT administrator.
Ask your administrator to submit a ticket via Microsoft 365 Online Support, including the exact steps to reproduce the straight-line drawing bug.
Disconnect the Keyboard Cover and Restart OneNote
A quick workaround to restore normal stylus functionality by temporarily removing the hardware trigger causing the glitch.
Try WPS Office for Seamless Note-Taking and Annotation
If OneNote compatibility issues disrupt your workflow, consider using WPS Office. It provides robust PDF annotation, document editing, and seamless stylus support on Android tablets without frustrating hardware glitches.
- 1. Download WPS Office: Install the free WPS Office app from the Google Play Store on your OnePlus Pad.
- 2. Open Your Document: Create a new document or open an existing PDF file.
- 3. Start Annotating: Navigate to the Draw or Annotation tab to use your stylus smoothly and free of straight-line glitches.
Frequently Asked Questions
Why does my stylus only draw straight lines when the keyboard is attached?
This is typically caused by a software conflict where the tablet's operating system misinterprets the attached keyboard cover's input state. It causes OneNote to lock into a 'shift-key' equivalent mode, which forces all drawn strokes into straight lines.
Does this straight line drawing issue affect other Android tablets?
While prominently reported on the OnePlus Pad when using its official keyboard cover, similar input conflicts can occasionally happen on other Android tablets depending on the firmware and the specific version of OneNote installed.
Can I fix this by reinstalling the OneNote app?
Reinstalling might temporarily clear the app cache, but if the issue is rooted in how OneNote handles the OnePlus Pad's keyboard connection state, the straight-line bug is likely to return until Microsoft releases a dedicated software patch.
