While using a recent rc-proposed image for arale (r243 from Feb 09 2015) I noticed that if proximity handling is turned on while the sensor is covered (i.e. the initial state is "near"), then only a single, initial "near" event is emitted and then proximity events stop.

Steps to reproduce:

1. Cover proximity sensor
2. Receive phone call or SMS, wait for notification
3. Uncover proximity sensor

Expected: Screen turns on
Actual: Nothing happens, screen stays off

Investigation indicates that the issue is caused by a level lower than USC/powerd, since the behavior can be reproduced by using just platform_api code (e.g., build and run examples/test_sensors_api.cpp).

The behavior seems to be specific to arale, I am not able to reproduce on krillin.
