[SOLVED] Problem with backlight dimming
When I soft-reset my TD2, leave it be for a while so that backlight dims and then press a HW button or tap the display, backlight comes up back again. However, if the device enters standby the "resume backlight on user activity" function stops working properly for some reason. (I am not sure for how long TD2 has to be left alone - maybe 30 minutes, 1 hour?) Specifically, if the backlight dims and I go to Settings > System > Power > Advanced tab and uncheck "Dim screen after X s", the screen will light up, but if I check this checkbox again, the screen will dim even though I just interacted with the phone and the screen should therefore remain lit up. The only other way to get a fully lit screen (at least until it dims again due to user inactivity) is to lock the phone and unlock it back.
I should also add that this happens with the official stock WM6.5 ROM.
Is there anything in phone settings I should enable or disable, or is there any registry key I should set to some specific value for this feature to work properly again?
Thanks for any help.
