Hi All,

I have a T46G on the latest firmware 28.80.0.95.

If I set the Backlight Inactive Level to low or off.

After the timeout occurs when the phone is not in use, the display will either randomly blink between the low and a high backlight or when the Backlight inactive level is set to off, it blinks (the display backlight comes on for a second).

I've tried resetting the phone to factory defaults.

Any Ideas?

I test here, everything work normally.
If you reset the phone, can the phone work normally again?
Is that the MWI cause the blacklight change the status? Please check.
