I've tried calibration and it doesn't work, the feature works because when I hold the front of the phone to a light the slider flies across to the right, it's just when say I'm in a room with dim lighting the slider goes to zero and the screen is too dark ??? Was ok before update....
I can't be the only one to notice this after the update ?

Thanks antiprotest
I did that and seems ok now, so whilst in a dim room I set the slider to where I want it, then I turned on lights and slider went up as it should, after turning lights off again the slider went back to where I set it !!! Hurray
Your method is simple and works great, the calibration methods i found on Google dont work or I'm doing them wrong ??
Anyway All sorted now, thanks again !
