Auto-Brightness doesn't work on Mango
Hi, My T-Mobile DVP's auto brightness doesn't work after i upgrade it to mango. It worked in pre-mango, if i cover the light sensor or light it up, the screen brightness would be changed. But it isn't like that in mango (version 7720), no matter i do, it is always at the lowest brightness level. The light sensor still works well in EM, it can detect lux value so i think this is a faulty OS firmware.
So after upgrading to mango i lost two sensors: compass and light sensor (Well, compass still worked in EM in pre-mango but in mango it doesn't work, even in EM). I lost my faith in Dell, too
. My Dell laptop dead one month after end of its warranty and cannot be repaired, now this one ...
Anyone have the same problem ?
