Frequently Asked Questions

Why does Microsoft Whiteboard lag on my Samsung Galaxy Tab S6 Lite but not OneNote?

Microsoft Whiteboard may require more intensive system resources for its continuous cloud-syncing canvas and rendering engine compared to OneNote. This can cause performance bottlenecks on the Tab S6 Lite's specific hardware configuration.

Will using Whiteboard Online in a browser fix the pen lag?

Often, it does not. According to user reports and Microsoft Support, the pen lag frequently persists on Whiteboard Online for this specific device, indicating an underlying hardware compatibility issue with the platform's rendering rather than just a local app glitch.

How do I report this compatibility issue to Microsoft?

You can submit your hardware details and bug report directly through the official Microsoft Whiteboard Feedback Portal. Detailing your specific device helps developers prioritize performance patches for older or mid-range tablets.
