I noticed my phone's backlight would start to flicker/pulse intermittently when I switch my brightness level to something low (est. between 1% to 15% brightness). The flickering or pulsing is as if the power supplied to the light is fluctuating.
My phone is a HTC Desire, OS used to be stock (Froyo 2.2) when I experienced this, now it is on CM7.2 (GB 2.3.7), still has this problem. I have not tried any other ROMs on this phone, and not sure if it is a software or a hardware problem.
Is there any way to prevent this flickering, other than not setting the brightness to such levels?
