OneDrive FAQs About OneDrive Android PDF Bug: Annotations Turning Into Straight Lines

Why do my drawn dots and curves turn into straight lines in OneDrive?

This is caused by a faulty ink-smoothing algorithm introduced in a recent update to the OneDrive Android app. The software incorrectly interprets curved handwriting and small dots as mistakes and forcefully straightens them into geometric lines.

Is my Samsung tablet stylus broken?

No. If you can navigate your tablet normally and the touch screen diagnostic tests pass, your hardware is fine. The issue is entirely isolated to the Microsoft 365 and Office | OneDrive | Other | Android software update.

How can I stop OneDrive from forcing the broken update on my tablet?

You must disable auto-updates specifically for OneDrive. Open the Google Play Store, go to the OneDrive app page, tap the three-dot menu in the top right corner, and uncheck "Enable auto update."

What should I use if I cannot install older APK files?

If your device is locked down by corporate policies, you should avoid the OneDrive PDF viewer entirely. Instead, use a stable alternative like WPS Office to open, seamlessly annotate with your pen, and sync your PDFs without experiencing handwriting distortion.
