Frequently Asked Questions

Why does Adobe Acrobat draw lines when I try to scroll?

This occurs when the application fails to distinguish between touch input and stylus input. Without active palm rejection or a stylus-only mode, the app registers your finger swipes as pen strokes instead of page navigation commands.

How do I turn on palm rejection on my Galaxy Tab S7?

Palm rejection is hardware-enabled by default on the Galaxy Tab S7. However, individual apps must be optimized to support this feature. You should check the specific app's settings for a 'Stylus Only' or 'Pen Input' toggle to enforce palm rejection.

Is WPS Office a good alternative for PDF annotation on Android?

Yes, WPS Office provides excellent support for Android tablets, including flawless S Pen integration, native palm rejection, and high compatibility with standard PDF formats, making it a powerful alternative to Adobe Acrobat.
