Features

* Display Accelerometer event frequency

* Switch between NORMAL, UI, GAME and FASTEST

* Display device and accelerometer type

Notes

The Screen off/Accelerometer bug is described in Anroid issues 3708 and 11028, see:

http://code.google.com/p/android/issues/detail?id=3708

http://code.google.com/p/android/issues/detail?id=11028

This app uses both a partial wakelock and the "re-register accelerometer events" workaround to assure only devices that really will not deliver accelerometer events when the screen is turned off register as having the bug.

If you have the bug and want to get rid of it, you can try installing a mod, like CyanogenMod. This works on many phones, but not all phones.
