I have have a new xperia mini pro sk17i phone and updated to the latest firmware Nov 2011. However the screen flickers, or the brightness changes up and down. I know from previous reading that it has to do with the light sensor on the front because if you cover it up the problem goes away, but that is not the point the software of the phone is changing the brightness, there is no setting to disable auto brightness only to set your own brightness at what ever level you are comfortable with. Why have this setting if the internal software messes it all up, seems ridiculous to me. Does anyone else suffer from this problem as my wife has the phone with the same problem and is there a fix possible?
