SPenCursorOverlay

A Magisk module for Galaxy Tab devices running AOSP-based ROMs.
Restores a proper arrow pointer for OTG/Bluetooth mouse use, while keeping the OneUI S Pen hover dot as the tap indicator.

Requires "Show taps" to be enabled in Developer Options.

What This Module Does

• Flags the S Pen device type as a touchscreen input
• Turns the pointer_arrow image into a mouse arrow again
• Replaces pointer_spot_hover with a OneUI-style S Pen dot
• Makes pointer_spot_touch transparent, so nothing appears when your finger touches the screen

Installation

1. Download the latest .zip from Releases.
2. Open Magisk → Modules → Install from storage.
3. Select the downloaded zip.
4. Follow the instructions and select the desired cursor color theme.
5. Reboot.

Known Limitations

• "Show taps" must be on — the S Pen hover dot relies on the tap indicator system and cannot be shown without enabling it globally.
• S Pen contact hides the dot — pointer_spot_touch is intentionally transparent, so no indicator appears when the tip touches the screen.
• Finger touches are also invisible — a side effect of the transparent pointer_spot_touch; tap indicators are hidden even with "Show taps" on.
• Changing the cursor theme requires a reinstall — resource overlays cannot be reloaded while the system is running.
