Hi all...first post on forums here. Been able to read plenty of good advice here so I thought it was time to register and return the favor. I have a relatively new curve 8330 with 4.3 s/w and was also annoyed by this backlight problem. However, I recently noticed it went away when I used the following combination:
Backlight Brightness: 100%
Backlight Timeout: 2 Min.
Automatic Backlight: OFF
LED Coverage Indicator: OFF (don't know if this one matters)
Well, the problem went away. It stays nice and bright for two monutes and then shuts off as it should. It's been fine like this for about a week now. Also, I think I took the battery out and put back in once during this time too. Maybe I'm just lucky with my curve or perhaps this exact combo must be followed as a workaround until they can fix! Good luck!!
