Some other findings I wanted to share: * The GPS sensor (GpsLocationProvider) must be doing something very different because it is never affected by these issues. Why?
* Seems to have been broken this way on G1 with Android 1.1, was then fixed in 1.5 (Source: http://groups.google.com/group/android-developers/msg/a616773b12c2d9e5) * GoToSleep function (called by pressing the power key) overrides all screen locks and actually releases them -- http://www.google.com/codesearch/p?hl=en#uX1GffpyOZk/services/java/com/android/server/PowerManagerService.java&q=goToSleep%20lang:java%20android.git.kernel.org&sa=N&cd=3&ct=rc -- which is why I got the idea to restore the DIM_LOCK after the GoToSleep (in ACTION_SCREEN_OFF) On Jan 14, 9:42 am, Artem - WorkSmart Labs <p.ar...@gmail.com> wrote: > Hi Dianne and other Android Team Members, > > Please provide some kind of comment on this long-standing and serious > bug: > > http://code.google.com/p/android/issues/detail?id=3708(one of top > bugs right now) > "OnSensorChanged() is no longer called in standby mode since last > Firmware upgrade" > > A lot of serious developers have looked at this, and we can't seem to > find a good solution that works for example on the HTC Hero.
