Screen brightness adjusts to zero by itself? - Desire General

I have the brightness setting set at 70% and sometimes it drops to 0% as I am using the phone, for no apparent reason. It isn't usually when the battery is low and I can see no consistent pattern. Can anyone help, please?
Thanks, in advance.

I think you have automatic brightness turned on. Go to Settings -> Display -> Brightness. Uncheck Automatic brightness.

Its a problem with the auto bright and the polling interval. its just not doing smooth transitions. Work in the settings to get it to smooth out. i used to have this issue, dont remember exactly how i fixed it though.
Are you doing anything with the special settings under automatic backlight in CMsettings? or just using the auto brightness in the regular Android settings? I'm using no special stuff in CMsettings and mine works fine.

Auto brightness always low

Using stock 4.0.1 here, and have always had the brightness set to auto. But it never seems to do anything? If I am in a light or dark room it is always dark, often darker than the lowest brightness setting.
I am just worried that the sensor might not be working, if the phone needs to be sent back it needs to be done soon. Anyone else with this issue? I know the sensor that turns off the phone screen when in call works, but the auto brightness might use a different one.

Auto brightness is just simply low on this device. There are some hacks in the dev section to increase it...but they don't work on my ROM.
I just started using juicedefender to adjust the auto birghtness
So auto brightness itself is broken and sensor is pry OK? I wonder if there are any apps to test it.

Simply put a bright light to it and watch the screen brighten up. The sensor is fine.. auto brightness simply is a little too conservative, probably because more people would moan about battery life than screen brightness.
My auto brightness works just fine. Sometimes I have to the screen off then on for it to adjust. Other than that, the levels are fine. I'm on 4.0.3.

Wake up brightness keeps resetting

While I'm at home in the evening, I've been trying to turn my brightness down to the lowest level. I tried the system slider and also tried different widgets and apps bit there has been one issue with all of them. Every time I put the phone into sleep/lock, the brightness setting doesn't stay are the lowest setting. (Auto-brightness off). The brightness would reset to 20 - 30%.

There's probably an app you have installed that is messing with it

Go to
Settings --> Display
There's another option called "Auto adjust screen power" which auto adjusts LCD brightness as well.
Just a guess really.. Hope it does something for ya

Stock ROM - Turning off Auto Brightness

Is their a way to turn off auto brightness? It is very annoying seeing the brightness level change so rapidly and I can't believe SE haven't picked up on this problem.
How do you guys manage with it?
Search the market for "Disable Auto Brightness Xperia", you'll need root though!

Is it something you use? Do you notice the rapid brightness changing with autobrightness on to?
Thanks
Does anyone else notice the rapid changing of brightness?
Thanks
I dont have an automatic brightness option in display settings..

Because there isn't.
I was just about to say... Cause I'd have it on and I can safely say there's no option for it on STOCK... It's manual control.

Screen dims

Anyone else notice that after turning the screen on it dims a little after a few seconds. I don't have auto brightness on.

It could be the thermal control kicking in.
To see if it is, when it does reduce the brightness, try to up it again with the slide control, if it's the thermal throttling, it'll say it won't because of the phone's temperature.

Most probably is because the CPU will be used a lot when starting.

What do you have your "Screen timeout" set to under Settings > Display? Mine usually dims a few seconds before turning off the screen. If you have a short timeout then it would dim very quickly.
I have screen off set at 1minute...tried raising brightness after dimming and it let me go to 100%...it is super annoying!
