You can read the state of the proximity sensor with

Code:

cat /sys/devices/platform/gpio-switch/proximity/state

if the sensor is uncovered, the state should be "open".
btw it does not make sense (I don't know if it is even possible)
to write the state manually.

Do you use a screenprotector, some people have problems with
the proximity sensor and some screenprotector.
