Or does anyone know how to turn off this annoying misfeature?
Optimized Backlight is the name sony gave to the screen content dependent backlight setting. If your screen has a big proportion of white or other bright colors, the backlight will be brighter as well, if the content is mostly dark, then the backlight will get darker.
This is independent from the adaptive backlight setting and can not be turned off.
I did try CM11 to get rid of it, but CM11 also has this feature.
Try - hard boot using vol up + power button. Z1 owners reported it works.

Nope.
But, I searched a bit, and this feature is called Content Adaptive BackLight or CABL.
So, for the custom ROM builders out there, what about the build.prop setting ro.qualcomm.cabl ? In the sony ROM it is set to 1. Perhaps setting it to 0 would work?
I don't have a solution, but I agree that this is an annoying anti-feature that adds nothing to the user experience or image quality, just gets irritating fast.
Small consolation: it doesn't seem as aggressive on KitKat ...

I dug a bit further and it seems that at least in some versions or on some devices with cm there actually is an advanced display settings dialog, where cabc, as they call it, can be disabled, but it wasn't there on my cm11.

Any solution to this yet? I'm guessing root is the only way? I find it annoying, but at least it's not as bad as the Z1.

I hope someone can help me out with this (I guess most of my posts arent worth bothering with as they usually go untouched by anyone). I'm trying to figure out a way to disable the touch button backlight on a Google Edition ROM. I have been searching for an answer since the Google Edition hit. All I can ever find is how to disable on GSIII ROMs (non ge). If anyone can please help me out I would very much appreciate it. Thanks!

Screen Filter is an app that can disable the backlight of the softkeys. Set it to auto-start at boot and you should be good. I know its not a direct fix but its a low impact app that shouldnt effect battery life or operation.

Yes, it did dim the screen, but if i uncheck the enable softkey back light, anytime I touch the screen the backlights still come on. Are you on a G.E. rom? I am currently on Infamouse G.E.

Go HERE i fixed the boot issue. I was way too tired last night xD missed something really simple lol
Hi,
Just a little trick for those who want the "capacitive" buttons always on (maybe not very battery friendly but...) Remember someone asked this a few weeks ago somewhere...
Obviously you need root and init.d support... You can also edit directly the brightness file in /sys/class/leds/button-backlight/brightness but the modification will not survive after a reboot so you need to use an init.d script to load the modified value at each boot.
Put the init.d script below in /system/etc/init.d set the permissions to rwxrwxrwx, reboot, done
Here's the script: http://www.multiupload.nl/SMQWQQVBTJ
If you want to return back to stock: rename the init.d script with the .back extension or delete it.
If you want to set the "capacitive" buttons always off you need to edit the value, open the init.d script with notepad++ (on PC) or with a file explorer directly on your phone and set the value to "0" instead of "255", save, reboot, done.
Hoping that it will be useful,
Won't be using but thanks anyways, one question though, when do the HTC one buttons come on and off normally? They seem to have no specific interval
Sent from my HTC One using xda app-developers app
Hi,
No worries , it works with the ambiant light so with the sensor (light->off / night->on), even if the auto brightness is on or off the capacitive buttons vary in brightness so this part is independant...
After that I'm not a dev, the only solution I found is to modifie the value by the user in one file. Maybe it's set in the framework, or kernel? i don't realy know. The auto brightness values can be changed with a modified framework-res.apk, maybe it's the same thing for the capacitive buttons . In any case I have not the knowledge and skills for this part about the "automatic" dimming...
Capacitive button in Play works well and less cumbersome. Am using it with Pie. Automatic dimming would be cool though Thanks for looking into this.

Hi,
Sorry but I don't know what you mean... or you mean a kind of greater "light graduation", not on or off like stock, at least it looks like this for me (for example some values like 0 / 100 / 200 / 255), depending of the ambient light?
Like I said, for this I have not the knowledge, maybe a dev can take a look . In any case I don't think you will see a big difference between 100 and 255 for example...
And in the path /sys/class/leds/button-backlight/ there is nothing related to the graduation, it's in the framework stuff I think...

Yep, it has 3 settings. Thanks for the idea about auto-brightness. You are definitely not the first person to pose that idea!
xperia z1 compact brightness change itslef even when i have turned off the auto brightness. for example, the brightness becomes dimmer when the overall display colour is dark or black colour and it becomes brighter when the ovrall display colour is white or bright colour. i mean im able to notice there is a slight change in display brightness when im viewing photo, watching videos or surfing inernet. the brightness just change itself even when i turn off the auto brightness. so is there any solution or is there anyone has same curcamstances?

I tried that, but the effect still appears. Any idea?
I've noticed the same issue, especially when browsing using Dolphin
Two ideas (which both may be totally wrong).
Does the phenomenon occur anywhere or only in certain apps? Some apps just ignore certain system settings and mess with the phone how they want or how is defined within the respective app settings (like switching to auto-brightness even when it is turned off in the android system settings). There seem to be some very basic points missing in the holy whatever-app-coding-styleguide for android: Options shall always be OPTIONAL and, in case of doubt (which is always), don't fcuk with stick to the system defaults ... but I'm running off the track here.
With auto-brightness turned-on, there may be some slight loop-back kind of behaviour in that a brighter screen also creates a brighter environment for the light sensor, thus, making the device turning up brightness even more. Things like that happen in control/measurement systems all the time (well, not really all the time, but they do happen). I've never seen it on my phone, though. So, this is a very very hypothetical hypothesis if I may say so.
Hi
I set ro.qualcomm.cabl to zero, and for me the irritating behavior went away., and unfortunately the irritating behavior is still there.
Thanks for the info!

That's strange because it's kernel related so changing the build.prop has no effect as already mentioned, which I can +1 to.

You are right, just placebo on my part, when duplicating the error case I noticed it in, the CABL is still there.

Thank you
I know this is for z1c, but I just got my hands on a z1 c6903 and it seems to do this a lot and fade on dark colours. I read that on 4.2.2 there used to be an optimized backlight option and disabling it would stop the screen doing it but it was taken out from kitkat. Does anyone know if any custom kernels would fix it? It's just really annoying.
What about setting:
/sys/devices/mdss_dsi_panel/cabc
to "0"?
Do you guys notice that auto brightness still On even when its turn off, i mean when certain images on screen change, the brightness change a bit depending on how dark or light the image is... Has nothing to do with light around you.
Try browsing a vibrant picture then change to dark picture..

installed any conflicting brightness or some sort of keep device wake up kind of apps
last thing you can do is take a back up of your current states
then do a fresh install wipe every thing
that can solve your issue
coz from where i can see settings for sensor is messed up

I'm planning to buy this phone. But bugs keep me from buying it. I shouldnt spend $700 with stupid issues it shouldnt have. Hope you guys know of a fix....
1. Can I turn off auto brightness without rebooting? Why no toggle for it in status bar?
2. No dark notifications... why aren't notifications dark?
3. Why does the EMUI look so outdated?
4. Some features not working with 3rd party launchers like Nova. Is there a fix?
Dont mean to sound like an ass. But I shouldnt have to invest almost a grand for a phone with issues other phones dont have. Its ridiculous. If you guys have solutions to these issues please let me know. Hope to join the huawei family without them.

The fact thet you're here in XDA tells me that you play more with your phone than keeping it bone stock.
1 - Nope, auto brightness isnalways ON which I find stupid.
2 - There is Dark mode that turn the system UI black including Notification panel but not Notification Banner.
3 - I hate EMUI
4 - You can't change launcher on most recent update and there no fix to that. You can on older version like 9.1.0.120 but you need an unlocked bootloader and root.
So do your self a favor and stay away from any Huawei Device and go with Oneplus or Xiaomi
Have bought this phone (UK version) but yet to recieve it.
Not being able to change launcher, is that an issue just for the china version or the international version too on the latest update? That would be a biggie.
Also are there any issues with notifications not getting through all the time (an affliction a lot of Huawei phones suffer from). I had the Honor note 8 (Chinese) and this issue made it infuriating to use. A phone without notifications working properly is a dumb rather than a smart phone in my book.
Lastly one of the best bits about the Honor Note 8 was the ability to clear the notifications by double tapping on the finger print sensor. Do you have that on the Mate 20 X?

who said that ? THEMES !! it comes will all sort of colors, just download huawei theme manager from playstore, it also including fonts as well
there is also a theme editor from the playstore where you mix and match and come up with your favorite theme all from your phone.
3. Why does the EMUI look so outdated?
because it is ! next month they are releasing a new version where they copied alot from OneUI, which is a good thing and they focused on smoothness and cleaner UI
4. Some features not working with 3rd party launchers like Nova. Is there a fix?
i am using nova, i think this is a chinese version issue not global

i have it for almost 4 months, and i got the note10+ with my renewal and trust me, i sold it without even opening the box. nothing comes close to Mate 20x as a complete package these days, its really fast, battery lasts forever, great screen, amazing camera, amazing charging speeds and one of a kind speakers.

PS: yeah, pretty sure not being able to change Launcher is only a Chinese problem. Cause I'm able to change it on my Mate 20 X in USA. I used to use Rootless launcher for quite a bit. But switched back because of the ? animations.

You can toggle it ON/OFF whenever. It does not require a reboot. Adaptive brightness turns ON anytime the device is rebooted. It is not such a big deal do not worry about it if you are going to buy the device.
