Xperia mini pro sk17i auto brightness

Thu, 08 Dec 2011 21:44:15 GMT

Is there a way without rooting this phone to disable the auto brightness function as it is annoying when the screen brightness changes.

Why put a setting for screen brightness when the internal firmware messes it up, that is just plain stupid.

I have seen programs on the app store that claim they can solve this but they dont, well the ones I have tried dont and most of them say they require the

phone to be rooted.

Thanks

If you set the screen brightness to max at Settings > Screen it will turn off the auto adjustment. It will of course use quite a lot battery but the auto setting should be inactivated.

Thanks for the answer but kind of missing the point.

If you have a setting for brigthness it should not be interfered with by the firmware and cause the screen to go bright-dark intermittent.

The battery life is not the best on this device so turning brightness to full is definately a no go.

Lets see if the icecream sandwich update brings a no nonsense solution to this ie PUT A SETTING TO DISABLE AUTOBRIGHTNESS surely you should be able to control features of a phone, especially when a feature is just plain daft.

Yes, this is REALLY stupid! hate when other decides what for me is better. I hate Sony's Bravia Engine in this phone..or screen is aweful. Mine chinese Huawei u8800 looks MORE better. This one have very non realistic colors, and they are washed out.too bright..

Why they removed option to use or disable auto brighness i don't know, my huawei have it.

Setting screen brightness to max doesnt turn off the auto adjustment! The light sensor still works!

Do you have the "On/off: Backlight" widget added to your home screen? Tap on this once if you do and to see if it this affects the auto setting.

Either way, what apps are affected by this? Does it always happen or e.g. only when in the browser?

The on off backlight widget simply switches between two brightness levels and in no way affects the auto adjustment.

The auto adjustment of screen brightness works everytime and is not specific to any application, i.e.it works even when the phone is idle.

The main disadvantage is that when one wishes to view picture or video in full brightness,apart from setting the brightness to max,he also has to move to an area with ample light. Otherwise the screen would stay dim or wil start to flicker.

I know it should not affect it but the info I have also says that the auto adjustment should not work when brightness is set to max. Just trying to figure out what could be the cause. I understand the problem but I cannot understand why it's happening.

May be its a software glitch.

Hope the Sony Ericsson team will take this matter into consideration,develop a fix and make it available on the next software update soon.

Yes, I've forwarded the feedback I've received here in this thread (thanks!). If it's a software issue I hope for a fix in coming software too.

If I stumble upon a solution or come up with something worth a shot I'll post again. Please do the same and let me know.

Does the Xperia mini pro have auto-brightness really? I dont notice any brightness adjusting in my phone. I dont see the auto-adjustment on/off checkbox too

how will I know if my phone's light sensor works? tried adjusting it to dark and putting the phone in a dark area but no brightness adjustment happens

Open the Dialer and enter *#*#7378423#*#*. This will take you to the service menu. Tap on Service tests > Ambient Light Sensor. Hold your hand at the top (covering the sensor) and see if the number changes (should drop).

Brighter area = higher value

darker area = lower value

This is what it read. Thanks mod for the help

And so if I put the phone in a brighter area, should the phone automatically adjust its brightness? I tried doing it but I do not notice some changes

Sure! And thanks for the replies!

Yes, the brighter area, the brighter screen. If you turn off all lights at the same time, going from a bright room to a dark, you should probably notice the screen brightness dropping.

It's quite hard to see this though since we're not talking about huge differences.
