Anyone come accross how to do this yet?
Brightness is set to maximum but dims when in low light.
Thanks.
As of the moment no way to set the auto brightness to off. Maybe some software update oughta to do it, or some genius gets pissed off and develop one.
I also noticed that when you force off the capacitive button lights (useful when dark) via software, the keyboard light will not turn on also (not useful when dark).
The x10 mini has locked auto-brightness too and it can be disabled this way:

Maybe it works on the mini/active as well?

Edit /etc/hw_config.sh using RootExplorer
1. change the line: i2c_pwm_als with i2c_pwm
2. set permissions to rwxr--r-- (744) if they are changed! VERY IMPORTANT!
3. reboot and enjoy the missing sensor

how and where do you do this? is this a setting somewhere? (cant find it)
or do you use 3rd party software? (if so, whats it called?)
^ Its an app on the market called "Screen Filter". I use that to further dim the screen (at nights), thereby save battery as well. And its free, as in really free, no ads at all unlike many "free" but has ad pushing. You can turn off the capacitive button lights when you prefer to setup a widget for it.

Looks like the format has changed in this file.
But this one looks interesting:
echo 1 > $dev/lcd-backlight/als/enable #Sensor on/off. 1 = on, reg 90h
I guess it can be tested "live" by doing:
echo 0 > /sys/devices/i2c-0/0-0040/leds/lcd-backlight/als/enable
I'm on a non-rooted build so I can't test myself :-(

I found another app, which may actually be better, as it turns off the backlight of the capacitive buttons, but leaves the keyboard backlight active when opened!
it's called "Keyboard backlight controller".
funny enough, this is supposed to disable keyboard backlight, but on the Xperia Mini Pro it disables only the backlights of the soft-keys!
edit: forgot to mention, this app needs root, so may not be for everyone.
Whoa nice find, I'll try that when I can

yes, this is caused by the auto brightness, which can't be turned off in the user interface.
I've played around with hw_config.sh file, trying to get it disabled, but to no avail.
Anyone else more luck?
I've found an application that works, it's called "Disable Auto Brightness".
It was made for another Xperia type phone, but also works on the mini pro (and I assume mini as well).
It works, but its somewhat unhandy: it'll disable the auto brightness sensor, but only after unlocking. so while using the stock lock screen, it works almost perfectly, but when using something like widgetlocker, it'll only work if you leave the system keyguard enabled (under advanced settings) which I don't really like too much.
so for anyone having these flicker issues, this is a fairly good solution.
but I'd like to have the sensor completely turned off.
soooo, anyone any luck with that?

correct. including another few different settings I tried.
they do have effect on the brightness of the LEDs though, but sadly no turning off the auto brightness of the screen.

By default the LCD backlight can be set to "30 to 255". But if you use your Streak in dark, you may want to get a bit lower.
With this you get the lowest backlight possible (it won't turn off on "0"). You may replace "0" with higher number (0 to 29).
"Night mode"
Code:
echo "0" > /sys/devices/platform/mddi_auo_wvga.0/leds/lcd-backlight/brightness
chmod 444 /sys/devices/platform/mddi_auo_wvga.0/leds/lcd-backlight/brightness
"Back to normal"
Code:
echo "30" > /sys/devices/platform/mddi_auo_wvga.0/leds/lcd-backlight/brightness
chmod 644 /sys/devices/platform/mddi_auo_wvga.0/leds/lcd-backlight/brightness
What you can do now
You can use app "GScript" to create your own "shortcuts" and put them on your screen. Unfortunately you will have to disable "Automatic brightness" manually to make it work (no code for that yet).
Future development
I guess it has to be possible to modify the backlight range from the default 30-255 to 0-255 and adjust the light sensor too.
I will try dig deep. If anyone knows more, please share.
This is awesome. At night, I like to use Amazon Kindle to read a book but it's still too bright. I may have to play around with this. An APK would be even better.

That's good to know. It only won't let you set 0-9 while the workaround with "chmod" works.

Thanks guys! on my second day on the streak and loving it. The community support makes me love it even more!

Thanks moneytoo...this works perfect.
How about turning it completely off?
I'm in the wrong thread because I'm running an Atrix, but perhaps in your adventure you've come across the relevant area to control off/on for the backlight on the Streak. On my old PocketPC I could stretch out the battery life significantly by doing this, and since it was just an LCD screen you could still view it enough to read ebooks just with ambient light.
Thanks in advance and apologies if this is considered hijacking.
Does not work on my stock 351...
If it's rooted, just use superdim or adjbrightness. Both could be found on market for free.

Didn't know about superdim, it works great. Thank you.
You can also just make the change using root explorer (if you are rooted), and the change takes place right away.
You just have to remember to change the permissions to 444 (read only to everyone) or the values change back with you lock the screen.
More interesting is that with read only to everyone only autobrightness can up the brightness.
I usually use Screen Filter app, available on Market
but I want to try this app

can someone please tell me how to disable auto brightness on
x10i eternity rom build 003

i tried using adjbrightness but it keeps telling me that my phone isnt rooted; anyone get this app to work on x10??
please help n sorry if this questions been asked and answered before. this forum is getting too big and broad sometimes to find anything
thx in advance
Have you tried Sparepart? (That's the name)
Strange, i can't seem to turn on my autobrightness. It used to work perfectly in android 1.6. And i haven't noticed it untill recently. When auto brightness is checked, it just stays the same, even when i hold it directly under a lamp. Maby there is a bug in the software that prevents switching it on or off?
I'd also like an answer to this problem, because with auto brightness on the telephone is a battery eater.. you have to keep it to the minimum level to disable it, but when you are under a strong light, like outdoor with a sunny weather, it's difficult to see your screen's details. as you select a brightness level different from zero, the autobrightness turns on and eats the battery.
I hope I'm missing the solution to this, and somebody will help, because all the applications i've tried (spareparts included) didn't worked.
I'm quite confuse now.....
What actually do we need......
Turn it on...
or
Turn it off...
LOL
heh, so some people want a way to turn it off and others, like me, want to find a way to turn it on?
what a crazy phone..
I'm sure there used to be a tick box in the display settings to turn on/off the auto brightness. Anyway, i've tried various applications myself to get it on but nothing does it. I think the best solution is for us all to swap phones .
Spare Parts doesn't work for me, i tried enabling it, restarting the phone and jumping under my duvet.. but it didn't change
Did you update to 2.1? It was disabled in 2.1 as far as I know.
So the easiest solution, upgrade to 2.1! Else, I don't remember the menu but it's somewhere in the settings under 1.6.
I think we've all updated to 2.1 here =)
and yes, in 1.6 there was a box to tick to unable/disable autobrightness.
But, in 2.1, this feature has disappeared, leaving a seekbar and a damned widget which doesn't allow you to set or no autobrightness.
Hi,
The autobrightness is still there. It can be turned on/of from a stock SE connection widget. The different state for brightness is "minimum" -> "auto" -> "maximum"

I can get, either 0%, or 100% brightness, with the ambient sensor disabled. Anything in-between, fades constantly.
No fix for this, i presume?
Reading websites while the screen fades in/out every couple of seconds drives me mad.
Ive never had any problem with it as long as you dont lean in front of it all the time lol.

Hello guys,
is there a way to let the browser stick to the global brightness setting?
Due to that rubbish 'feature' I always end up changing the brightness twice, as if once isn't already enough.
- wake phone
- think auto brightness is too bright -> turn it down
- start browser -> still on auto -> still too bright - aaarghhh!
later again:
- went outside
- wake phone
- put to auto again - looks fine
- start browser
- black screen FFFFFFFFFFFFUUUUUUUUUUUUUUUUUUU
Please tell me there's a work around! This is so annoying and so useless!
There is an option in the display settings about "Auto adjust screen power" and I thought I heard that this adjusted the brightness when there is a lot of white on the screen (like a browser) to save power.
Try this?
Good idea. Unfortunately that's not it. But thanks for the hint, i've seen that dynamic brightness thingy in action and wondered whether i could turn it off.
No, it seams to be a less obvious solution. I'm thinking of the trick to change the user agent. Something like this, but there does not seam to be a about:settings or similiar. Any ideas?

You can change the useragend using about:useragent, but doesn't have anything to do with brightness settings.

Yeah this guy's right, the user agent doesn't have anything to do with brightness or the backlight at all. All it does it trick your phone into thinking it's a desktop PC so it doesn't show the mobile version of websites....as for the auto-brightness, have you got XWKE2 installed? Samsung have much improved the auto-brightness from XWKE1 and XWKDD.
You guys got me all wrong. I meant just like Samsung hid the option to choose the user agent, there must be a place to disable this annoying 'feature' as well. I know what the user agent does, don't expect me to be a total retard because of my 1 digit post count

Hi,
Since a couple of days I've noticed that my screen flickers sometimes.
Mostly when I'm moving my hand while holding the phone...
Is it possible that the light sensor auto adjusts my screen brightness ?
If so, how can I turn it off ?
Thanks in advance,
Niels
If you have rooted the phone, you can install Disable Auto Brightness for Xperia phones. or you can disable it manually editing the file /ect/hw_config.sh.
Search the forum for the tutorial
Thanks for your answer !
So unless you start rooting or changing files there's no way to stop the flickering ?
Unfortunately, no. By the way, this problem usually affects st15 models... as far as i know, you've been unlucky
Okay, I'm sure now that it's really because of the lightsensor and not just a problem with my screen.
I was standing near a window and when I put my finger on the lightsensor a few times the brightness was clearly automaticly adjusted...
I'll look for the tutorial, thanks for the info !
Other solutions, if any, are still welcome though

Hey, my ST15i does also automatically adjust the brightness....it's not a problem mate When i am outdoors the screen get brighter but when i am indoors my screen automatically gets darken
Yes I now, but I find it annoying, it gets flickery sometimes..
I want the screen to stay on the brightness I've set.
today I was wondering why this phone doesnt have auto brightness adjustment feature, because I have to manually turn brightness to zero when using phone while on bed at night. I looked into settings and no such feature found, I wonder the light sensor actually works
Yes it does, I've tested it.
Try standing near a window or holding it near a lamp and put your finger on the sensor... (The screenbrightness may not be set to 0 if you try this..)
I too find it strange that there's no possibility to set the auto adjust on/off..

I don't think there is any auto-brightness option in LWW as I've not found any. if there were any then they would have provided an check box option turn it on/off. but the brightness ups and downs happens to me to specially when i've put the brightneww to lowest level at night. could not explain myself.
yup it works (just checked thru window operation )

The fact that you can't turn it on/off doesn't mean it doesn't work. Actually, the auto-brightness is always on. You can disable it manually editing /etc/hw_config.sh or using the app Disable Auto Brightness Xperia. You need root anyway.
I've noticed that no matter what setting I have it on, my tablet (M5 8.4) automatically lowers the screen brightness in Chrome and YouTube, but more noticeably in Chrome.
Any way to disable this?
Have you checked the setting menus?
Using Firefox might be a solution.
Also, Youtube in FF has background playback as long as you are using a desktop user agent.

I've checked every possible setting, and read online everywhere, but to no avail. It also dims in Firefox. It dims as soon as you go into the app. After an online search, I found many Huawei owners with EMUI 8.0 having this issue. There is one solution, but it requires root and I don't want to root my device after having it for a few hours.
Funny. Would love a solution as well as this is rather annoying
Do you guys have auto brightness turned on or off?
I never really experienced this issue, but I did observe strange brightness behavior before I began to keep auto brightness permanently enabled.
Doing a quick search, I saw one person say to turn auto brightness on, I saw one person say to make sure animations aren't disabled in dev options, some say unclick 'increase readability in sunlight' in dev options. I personally wonder if the stock launcher (which I don't use) maybe is set to override the brightness level.

Well, I went through with it and rooted it. I tried the fix, and... it worked! After you're rooted, simply freeze the system process (I used Titanium Backup) called PowerGenius, reboot and no more forced-auto brightness dimming.

Just disable "power genius" this has worked for me. without root. No More auto dimming.
Disabling Power Genius will also get rid of issues involving bluetooth music playback, and will prevent apps like Google Maps from getting killed off semi-aggressively in the background (i.e. so when you map out driving directions you won't have to reenter the address as you get close to your destination).
Quick note: you have to reboot after disabling Power Genius. Merely disabling it won't immediately change anything.
Up until now I thought a reboot would bring the "wonderful" feature back ...
How comes that you mention a reboot is needed?
How do you disable it? I can only do a force stop
I'm not sure how to disable it without root (I imagine adb might work). With root, most use Titanium Backup to freeze it. I'm using Service Disabler to disable the associated services instead. Service Disabler is awesome if you are rooted, underrated app and great for EMUI because, for example, you can disable individual parts of the Tablet Manager app without breaking the features you want.
You might not need to reboot. When I initially froze it using Xposed Edge Pro, but didn't reboot, it didn't change anything for me. Could have been due to Xposed Edge Pro.
