maybe use infrared proxi, same as for camera door mount to bottom side of UPPER, looking thorugh two "windows" in lower to either stylus (no light path, aka "dark") or silver steel surface on backside of stylus bay (light path clear, "bright") Two windows, to block bad light path reflecting from surface of stylus. Might also work with one window for both RX and TX with original stylus which has been tested to not reflect enough light to make front IR proxi sensor switch to "close" state: IroN900:/sys/bus/platform/devices/proximity# watch --interval 1 cat state See attached sketch

Try to restate your system if you are still facing the issue and always do testing first. The https://www.australian-writings.org recently publish a guide about it so It might help you to fix it as soon as possible.
