Brightnes sensor - LG Optimus 2x

Hi,
I installed few app for brightness controll (lux, velano) but both reported that phone don't have brightness sensor and offered to use camera sensor instead so I am not sure is it true or not?

Maybe the problem is that you are using a custom rom which was mainly developed for p990. And your device is not p990.
I have been searching for a quite long time what can cause these problems with brightness but with no result.
Also I found out that you are the only one who has got problems with brightness.
Solution for you should be a factory reset or you can install another custom rom.

Hi,
I am curently using ROM from my signature... I will try stock and check if sensor will be recognized by app (if is exisiting in this device)...

Automatic Brightness Malfunction

To those with more experience with Android/HTC phones, what do you think about this issue? It is odd that these phones were shipped with this feature clearly not working (because this feature doesn't work for all of them - right?).
Do you think it is a software issue? A hardware issue? Or both?
And do you think it likely that this feature will ever work? There has been no real information from Google/HTC about this.
I love this phone, but it would be nice if the feature actually worked!
Auto brightness has been tweaked for the N1 in CM... after that tweak, I find it quite good...
I'm using CM 5.0.5.2 and the auto brightness oscillates up and down...

Don't hv this problem... tho it takes a couple of seconds to adjust to the light
Just updated to 5.0.5.3 and no change. So must be a hardware problem?

Wait, so is it that some people had the cycling up & down auto brightness problem - but then using CM fixed it?
Its not that big a deal, I can just use the static brightness - but I'm just curious how many other ppl have this problem, what you think is the cause, and if you think there will ever be a fix.
I also notice that if the brightness is low, I get a red/purple hue - is this related? What causes it?

Anyone got the Light Sensor working on the JB?

Mine is TL and flashed the UK generic JB firmware via Flashtool. The JB upgrade is great, however recently, because the strong sunlight on Texas, I noticed that the light sensor was no longer working. I've tried to erase the data, reset, and reflash. None of those made the light sensor working. Is everyone got their light sensor working on the JB so that's only TL's problem or it's actually not working on the JB?

the ALS shows a 0 when checked under the service tests, but the screen does change brightness depending on light conditions.
My Xperia T light sensor stopped working as well after JB update.
Sent from my LT30p using xda premium
I have some issues also, brightness is set to auto but when entering from sun light into the buildings where the light is low, the screen remains at full brightness and the sensor is working ok only after i'm locking the screen once.
ALS sensor works, differently from ICS, but works. It takes more time, decreasing the backlight when coming to low light conditions and sometimes it takes more time, increasing the backlight in high light conditions after waking the screen. This could be a little faster.
And I suggest disabling DLS, it's annoying and I see no benefit from using it.

This describes the behavior I had on my TL with ftf's from UK or CE. If it doesn't happen right away, it's just a matter of a short time (less than a couple days) until it begins. Once it starts, the behavior doesn't go away.

I had exactly the same problem. Dealt with it by wiping /system, /cache, /data partitions in recovery, booting the phone (of course it stopped on Sony logo) and then flashing JB again. But I'm not sure you could do this on TL. I think you will lose LTE then.

I've used: LT30p_9.1.A.0.489_1265-1626, Xperia T_9.1.A.0.489_Europe and OTA upgrade from LT30p_7.0.A.3.223_(1267-4649), same issue with all these versions.
All versions were installed with full wipe.
Can some one see if it is only in this ROM? Try another jb rom and confirm. If so then someone can look into it with me.

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.

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!!
Hello Guys,
Yesterday I received the August 1 Update on my note 8.
After the update, I confirm the matter has been tackled
Screen rotation, auto brightness all working fine now.

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 ?

Mi8 Display flash Problem

Hi,
I have a Problem with my mi8.
The Display flash

Aod ?
toniq1 said:

Always on display. Sametimes it's help but it's probably fault of ambient light sensor or screen.
It is the same If aod Off
Not good
That's a common thing with faulty oled screens, it is a hardware issue
I have the same flashing screen when I turn the screen off before the aod is displayed. It does not happen all the time. Turning off aod does not help. I doubt that it is a hardware issue as the flashing started after updating to MIUI 11 - at least for me.
I have also this problem, started a while ago when I was on MIUI 10 after I installed some kind of dark theme
This indeed looks like a AOD fault cause turning it off solves the problem, and the latest version of AOD with custom picture customization, reduced this issue for me
But it also seems like it mostly happens when the ambient light is low so the automatic brightness reduces the screen light and AOD starts to flash
I hope it won't be a hardware problem
One other thing that I want to mention is sometimes it goes really bad and the screen starts flashing for a long time, in this case phone seems to become unresponsive as not touch and not the fingerprint sensor and infrared camera doesn't work at all

It is used for past time if you're asking
So a little update on the flashing screen situation
I disabled auto brightness and set the brightness a little below middle of brightness bar and so far so good. No flashing here for a while
Also disabling the AOD completely solves the problem
Another update on the state of this flashing issue, after Android 10 update haven't seen any flashing so far, AOD display works fine, light sensor and automatic brightness work just fine.
I guess it was a software issue after all
I hope you have solved it. Do you have the anti-flick on?

Nope I don't
Anyone else who has this issue:
Try disabling hardware overlays in developer options, also check to see if the Game driver option within Developer options is set to default. Although its possible that this could be the beginnings of a hardware issue, it could also be a software related issue.
If none of the things that I mentioned work, i would try reflashing the stock fastboot rom. ( must be fastboot version)
Similar happened to me but i think this is not recoverable.

No matter what i do, it only flashes and nothing else is visible. Device purchased about 1.5 years ago.

You need to return to stock using a fastboot rom, using a recovery rom will not work.
Most likely you have corrupted files. but sure it could be an hardware issue, especially if you have dropped the phone or installed something to increase the refresh rate. If you flashed a refresh rate mod, then you need to flash the DBTO image from the fastboot stock rom.

I have TWRP installed and thought of checking it out but it simply flashes there as well. Right now i have the display on, set never sleep in Developer options and simply keeping it up until new phone arrives. Once i am on new phone, i will try factory reset on this first and go from there i think. Not sure how to get to fastboot when display is not working.
Due to such weird nature that nothing really helps i tend to think that this is HW issue.
EDIT : Turned off display by accident (because phone call happened) and now it's back to flashing disco with absolutely nothing working. Fastboot (power + lower volume key together) is of course flashing as well so inacessible.
Happened to me too. Turned off AoD, restarted, turned on and it was ok for a while. Now flashed again. Dont know what is causing this :/

I also got the same issue on my dipper. The only solution that works perfect is by flashing to LineageOS 17.1. I know it's an OLED screen faulty but Lineage really fixes it. Been using Lineage for a few months and never have this display issue again. Other custom ROMs can't fix this display issue.

Question Auto brightness problem

Hi all, I used this 11 ultra for about 3-4 months, everything work well, but suddenly in few days ago, my screen auto brightness is darker thân before. I think auto brightness sensor is dirty or some dust maybe block it from function. But i dont know where is that sensor to clean it

Can't help you then. One of the reasons why I like this phone is that you can enjoy the superior hardware while fixing any software issues (which you can be sure to expect) because it's so easy to root
