auto screen brightness - Xperia SP Q&A, Help & Troubleshooting

I instaled 254 stock fw and seems like auto brightness is not working. When I chech auto, it just dims screen a little bit and that's all. It was the same on existenZ rom. Seems like it only worked only in CM11. Is that a common thing or is here some workaround?

Coming from Atrix 4G, i found the way the xperia SP handles auto brightness is pretty bad...
So i tried Lux, but it looked like my light sensor was screwed up... always returning 1 or 2 lux.
So i searched and managed to get it working again by installing this tool first, to disable auto brightness:

Then Lux would do the trick :

Same here. Auto brightness is just low brightness. Something is wrong with the stock 4.1 because on SlimKat it works well.

On Existenze 3.30, which is JB 4.3, auto brightness also is not working (or at least not working as I would expect it to be). So I guess its just has something to do with sony framework or smth.

Stock auto brightness (4.1.2/4.3) never worked properly for me. I'm using 'Velis auto brightness' app. Works like a charm..

[Q] Automatic Brightness problem

A few days ago I started to use the Automatic Brightness, but it doesn't worked very well...
When I am in bright area , the brightness increases, but when I leave the area or cover the brightess sensor, the bright the screen should change his intensity, but he remains the same, at high brightness. The brightness decreases and becomes what it should be according to automatic mode only after lock-unlock screen.
Anyone can help me?
I think the sensor dont have problem.
I think if you check the option "Display -> Brightness -> shade bright screens" (or somethink similar to that, i have to translate) it could make it work properly. A broken brightness sensor doesn't control anything anymore, my old DHD had one.
i think its a software problem
Same problem on my razr i
But on some razr HD, there isthe same problem. Maybe the software version....
I use "custom auto brightness" apk on market, and work great for increase AND decrease brightness.
For information, same problem with JB 4.1.2 update...
Anyone have the same problem and a real solution ?
::/
Thanks this app worked very fine!

Auto brightness apps break light sensor

On my Xperia T running stock, rooted .141 any time I install an app such as Lux or Velis, they detect the light sensor (and CPU-Z does too) but after a very short time neither brightness app nor CPU-Z can detect it, and Sony's 'adapt to brightness conditions doesn't work properly. Uninstalling the app and rebooting makes the light sensor work again.
Can anyone else confirm that this is the case on their device also?

I am facing the same issue with V. Rebooting makes lightsensor work again.
Any solution available?
Very common issue on our devices : http://forum.xda-developers.com/showthread.php?t=2453223
Mine does not work anymore at all... Perhaps it will wake up one day...

Adaptive brightness weirdness

This is my first Lollipop device after a long time with Kitkat, so I may be missing something obvious, but I just can't wrap my head around Adaptive Brightness.
So when it's set to on it adjusts the brightness based on the light sensor, but I can also use the slider to tweak it, correct? But then sometimes the slider just stops working, moving it doesn't change the brightness at all. Only way to make it work again is to change the lighting significantly (for example I point the phone at a lamp). After the auto-adjustment kicks in I can tweak it with the slider again. Is this a bug, or yet another misguided "feature"? Do I have a hardware problem? I've tried a few sensor apps and everything seems to work fine. On top of the auto adjustment not being as good as Kitkat's, the inconsistency is really bothering me.
EDIT: I am on stock rom. I'm sure that CM12 would solve this problem if it's a Lollipop bug, but I can't be arsed with a custom rom a this time. Looking for a stock based solution, or at least an explanation for this strange behaviour.

Brightness issue on Mirek190 v 6.1 and 7

I have the C5J6 model and before upgrading to Mireks roms I was on the stock rom. While on stock my brightness was controllable, ranging from the expected low to very bright. After upgrading to Mirek v6.1 the brightness option was no longer controllable and appears to be at a set position. I can still move the brightness slider, but nothing actually happens. I have just moved up to v7 and the issue still exists.
I have the dual boot model, so to be sure I wasn't loosing my mind I booted into Windows and brightness is controllable and very bright at the highlest level, as I like it. So I know it's definitely related to something with the rom or Android in general.
Is there a fix to this, or something I am missing?
Aside from this Mireks roms have worked beautifully.
Thanx!
I seemed to have resolved this by installing a brightness app which worked on its own and then seemed to restore functionality to the native brightness control.

Auto brightness issue

Has anyone noticed an issue with the auto brightness of the note 8 ? It seems it doesn't get adjusted efficiently! Sometimes it's too dim and sometimes too bright, that's so disturbing
It's really funny, it worked after I installed an application called lux lite, that's unbelievable.. I need to install a third party application on a 1000$ cellphone to get such a basic function working. Thanks Samsung !

I believe you are wrong about this. The auto brightness is adaptable, in the sense that you can set it manually wherever you want in different comditions and it will learn your preferences and interpolate. I actually find it very flexible.

I find that is not doing such a hot job at learning my preferences. I keep having to manually adjust because my phone thinks it knows what I want. It's annoying.

do you mean that it has a new functionality that has not been in old phones? I have the Note 4 and it works like a charm, but the note 8 auto brightness works strangely, when I'm in a room with low brightness the screen light goes so dim that I can barely see anything!
Ive experienced the same thing, I have to do a screen lock for its auto brightness to work correctly
Hi,
(sorry for my English)
Your message was one month ago but I reply just in case some people have the same issue.
You have to call samsung about your issue. I have done that there are 2 months ago and Samsung are going to change the settings only if they have lot of complaint about this weird behaviour of the note 8, S8 and S8+.
The new settings of the auto brightness is "smart" but often it's more like "lost" than "smart"... :/
I adked to Samsung to give 3 choices for the settings of the auto brightness for the user instead of 2:
1) manually
2) auto "smart"
3) auto "not smart" => so the phone adjust the brightness depending only of the light sensor.
They told me that my proposition can be integrate only if they received lot of complaint.
Seems to come with last update
I can confirm am having the exact issue..
Brightness doesn't seem to auto adjust. Even after a reboot. The issue seems to come during the last update - the update where now we can have video lockscreen and animated AODs.
Hope this is resolved soon.

I don't recall having issues on the last update, but I am on the latest CRG1 now and it's working fine on my N950F.

I ran the sensor tests, and it seems that more than the lux sensor is not responding ...
My heart rate sensor seems to work on a hit-or-miss basis..
SpO2 working fine though.

Try and reset your usage pattern and give it time to learn your usage. You will have to adjust the slider for your preference while its learning. I'm on the latest oreo and have no issues with it.
Reset phone to factory settings..
Issue persists!!

That's strange. My auto brightness worked fine up until the latest update. It is the August update that caused the problem for me.
Actually, providinf an update on the matter.
Some days later, situation came back to square one!
Not working:
Light sensor
Heart Rate sensor
Proximity sensor
Gyro sensor
Magnet sensor
Accelerometer
Just fingerprint sensor seems to be working fine.
I was on a trip in Malaysia and was at a Samsung store. They told me this is a very common issue and easily solved by 'software update' but when I went on to the service centre, they denied me since my phone was bought in different country. Phff
If the next OS update doesn't resolve this then I would recommend that you take your device to a Samsung Service Center
Anyone got their unresponsive device working back again ?
