Stock ROM - Turning off Auto Brightness - Xperia Arc Q&A, Help & Troubleshooting

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

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 brightness adjusts to zero by itself?

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.

isn't the same!
You can set it to leave the screen on dim when it's plugged in, but I don't think that's what you mean is it?

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.

[ION] Totally disable auto-brightness on Stock ROM?

Hi, guys.
As you'll already know, Xperia Ion Stock ROMs have no auto-brightness toggle on settings, apparently. And even if you use a 3rd party app to fix the brightness at a value, it keeps blinking around that value according to light sensor.
Light sensor has always been told to be such a battery-drainer, so here's my doubt:
Would it be possible to create a mod, app, flashable ZIP or something to disable that auto brightness feature at all?
Thanks in advance.
Lol? Light Sensor isn't battery drainer. You have wrong informations.
Sent from my LT26i using xda developers-app
Light sensor constantly reads an input, that obviusly uses a substantial amount of battery.
Anyway, is there any toggle solution?
If you want to really disable it, try this -
0. MAKE A NANDROID BACKUP (VERY IMP)
1. Use a root file manager and go to /system/etc
2. Open hw_config.sh
3. Search for this line - echo 1 > $dev/lcd-backlight/als/enable
4. Change 1 to 0, then save and reboot
5. Hopefully it should disable als now.
Thanks for the method! But wouldn't that disable brightness at all? I want brightness on, but light sensor-based automatic brightness disabled.
Greetings.

No no, you can adjust brightness in settings. It only disables the ALS sensor(Ambient Light Sensor). I have tested it myself.

Auto brightness doesnt seem to work

so the brightness control. it clearl has an auto setting but it doesnt seem to really do anything. is it me or it is just broken or what?
I have the same issue. Specially on a bright day the screen is bearly visible. Can resetting the whole phone help?
Works for me with Eragon v9.0 - what Rom are you using?

in settings/display enable the adaptive brigthness,
that will activate the sensor.
after you set it and its dont change the brigthness values, make a reboot .
