If your stylus draws, highlights or registers clicks without physically touching the display, this is not normal behaviour. The most likely cause is the stylus nib or its internal pressure sensor registering pressure before the pen reaches the screen.
1. Check the stylus nib
Inspect the nib for visible damage, bending or debris.
A stuck nib can apply constant pressure to the internal sensor and cause phantom input.
2. Replace the nib
Each Star Labs MPP stylus includes a spare replacement nib in the box.
- Carefully grip the existing nib close to the tip.
- Pull it straight out of the stylus. Avoid twisting it or using excessive force.
- Take the spare nib from the original packaging.
- Insert the replacement nib and push it gently until it is properly seated.
Test the stylus again to see whether the phantom input has stopped.
3. Fully charge the stylus
The Star Labs MPP stylus has a built-in rechargeable battery and charges via USB-C.
Connect it to a USB-C charger and allow it to charge fully:
- Red LED: The stylus is charging.
- Blue LED: The stylus is fully charged.
When the LED turns blue, disconnect the USB-C cable and test the stylus again. This rules out unusual behaviour caused by a low battery.
4. Test for phantom input
Move the pen towards the display without making physical contact. Check whether it registers drawing, highlighting or clicking while it is still hovering.
It is normal for the StarLite to detect an MPP stylus when it is hovering approximately 1 cm above the display. It should not register an actual pen stroke or click until the nib touches the screen.
5. Tell us the result
If the stylus continues to register phantom input after replacing the nib and fully charging it, the internal pressure sensor may be faulty.
If you are using the original Star Labs stylus, contact Star Labs support and let us know the results of these checks. We can investigate a warranty replacement if the problem persists.
