I've never been happy with the way the autobrightness works on my phone, and after checking with AndroSensor and the calibration in Total Screen Control, it seems the ambient light sensor doesn't read anything below 160 lux in sense roms, and 320 lux in CM7.
Is there anything that I can do regarding drivers, settings etc. , or is a replacement my only option?
I don't really want to go there, because I paid for a SIM unlock code and everything else is working perfectly, but it annoys me that I have to use workarounds to deal with the brightness, and I always find myself get stuck with an unreadable screen (too dark), when out and about, because I forget to set the brightness higher before leaving.
Can anyone tell me where I can find the relevant files for the ambient light sensor on the Dinc2?
This is where it's at on a Desire, for example:
/sys/devices/i2c-0/0-0066/ls_adc
And what would be a good stock rom to see if it happens with that one, too?
I Honestly just use the quick settings slider to adjust screen brightness
I do, too, but it doesn't do me any good, when I have to use the phone outdoors, and have forgotten to set it to full brightness, before leaving the house!
That happens to me frequently, and the screen is unreadable then, so I can't find the brightness settings.
go to Setting,display.
Well, yes, but if my screen is too dark to see anything, I can't navigate there.
That's why I'm trying to pinpoint the sensor problem, so I can use AutoBrightness.

Using stock 4.0.1 here, and have always had the brightness set to auto. But it never seems to do anything? If I am in a light or dark room it is always dark, often darker than the lowest brightness setting.
I am just worried that the sensor might not be working, if the phone needs to be sent back it needs to be done soon. Anyone else with this issue? I know the sensor that turns off the phone screen when in call works, but the auto brightness might use a different one.

Auto brightness is just simply low on this device. There are some hacks in the dev section to increase it...but they don't work on my ROM.
I just started using juicedefender to adjust the auto birghtness
So auto brightness itself is broken and sensor is pry OK? I wonder if there are any apps to test it.

Simply put a bright light to it and watch the screen brighten up. The sensor is fine.. auto brightness simply is a little too conservative, probably because more people would moan about battery life than screen brightness.
My auto brightness works just fine. Sometimes I have to the screen off then on for it to adjust. Other than that, the levels are fine. I'm on 4.0.3.

I've seen a couple posts about delays with adaptive brightness, but this is a different item. I'm seeing that the adaptive brightness alters the brightness a little too dramatically. In a somewhat dark room (not pitch black) the brightness will be at absolute minimum even when the brightness is about 1/3 up on the slider. In a moderately bright room that same brightness setting will be near maximum.
Does anyone else notice this as an issue? I'm just wondering if it's normal (ie, software calibration issue) or if the brightness sensor might not be seated correctly.
It's normal. Or at least it sounds like it is working the same way mine is. And yes, IMO it is a little too sensitive. The Lux app works beautifully if you want an alternative. Also, the goog is known for tweaking this feature over time with updates.
I've noticed this too. The biggest thing for me is walking down the street at dusk (so not dark out yet) I can't read the screen as it turns it all the way down, then, when I walk under a street light, it turns it all the way up to full! It's one extreme or the other, there seems to be no middle ground.
In other words "adaptive brightness has mind of its own!"
This is why I have always kept this setting off. The brightness just changing on its own always annoyed me.
When it works properly (and it should) for ones uses, it's great, it's automatic, what's not to like? It's a pita to always have to change brightness manually just to see a phone display depending on ambient lighting which varies immensely for many users.

I agree. I have it set to maybe around 15-20% (centered over the WiFi symbol below it) and I never need to touch it. Gets dark enough for night driving and bright enough to read outside. Never found it stuck on one or the other when it shouldn't be.

If you buy the app Lux you can customize how it adapts your brightness. The free version is good to but you have to use mostly default settings. By default it only adapts brightness when the screen turns on.
Hi everyone. I haven't seen the related kinds of thread so I decided to post it. My device model is G3223.
tl;dr: It's too bright at minimum brightness during nighttime.
So during daytime the screen looks perfectly fine, no problem reading under the sunlight. But when night comes the problem arises because the phone can't go dimer, which means that the phone is still quite bright compare to my other devices when I am trying to read in bed even though the brightness is set at minimum.
Does anyone also facing this issue? Or if it's device model related?
I have the G3221 and I have the same issues. But I found 2 solutions to the problem. (well kind of) if you disable automatic brightness ? setting it will be way too bright. After enabling the auto brightness you can lower it even further. But if it still feels too bright, you can change the white balance settings to 255 which will lower the brightness even further without actually affecting anything. I hope it helps a little. ?

Problem solved. Thanks a lot. I don't know why Sony doesn't allow us to change the brightness to the real minimum point without using automatic brightness.
For white balance I set my phone to a warm colour. For (255,255,255) [r,g,b] the screen looks too cold though, and it can also lower the brightness. I am currently using (255,147,0) so it's at least better than the original setting (0,0,0)
Speaking of warm tones, sony also hides the blue light filter in the actions section which is almost invisible and many people don't even go there. You cannot enable it otherwise. They need work on their stuff.
You can use the Twilight app to use the phone at night without stressing your eyes. It works for me when I'm reading things. ?
And of course you can use this to lower the intensity of the screen's light if not the overall brightness.
Hope this helps.

Thanks for your advice. As far as I know, apps such as twilight only draw an overlay on the screen, which means it actually doesn't affect the brightness in any ways. It just seems to be darker.
In contrast, decron04's solution can actually decrease the brightness. Don't know why Sony doesn't allow users to minimize brightness without using auto brightness.
Worked Perfectly fine on Oreo but ever since the update when unlocking the screen Display Brightness goes to 0 if i have adaptive brightness on.
anyone else having the issue? so far only solution is to turn that feature off

You will have to keep the feature on and keep on correcting brightness when it's too low, until the system finally understands your preferences
It took me almost 2 full days constantly playing with brightness slider, but now it's all good :good:
Seems that brightness artificial inteligence is a bit lazy....

really? that's a lot of work for someone who unlocks the screen too often. i prefer older auto brightness where you set a base amount and forget it.

I agree with you, I think that the learning is a bit long and I don't understand the need to always go back to zero (it's painful)
But I must admit that once the system is calibrated, it is more efficient than the older one
This is because it is based not only on the ambient light, but also on your personal preferences.
Give it a try, If you unlock your phone very often it should take less time...

I did not have this problem at all after updating to Pie. I never had to manually readjust.
Maybe try to train you light sensor by placing it under bright light (it should then be on the highest brightness) and afterwards in complete darkness (brightness should be lowest now).
After having witnessed very bright light and complete darkness, the sensor should already have it's baselines and should actually switch accordingly.
However if you for any reason still don't like the low brightness in dark rooms you would obviously do that manually.
Hi
Does anyone else find the adaptive brightness feature useless on the OnePlus 7t? It is supposed to learn how you like it and I adjust it to where I want but it always seems to forget this settin and goes too dim on an evening. I adjust it again thinking it might stick this time but then goes at back to being dim.
Cheers
Same issue for me. I decided to keep it manual.
Apparently it takes a few days to learn the brightness you like. I'll give it a week or so and adjust it manually when needed to see if it sorts itself out.
I've opted to use velis auto brightness until they hopefully fix it. I gave it 5 or so days and it still dropped too low in dim light even though I was manually moving the slider up each time.
Velis auto brightness seems to work pretty well on Android 10 so far. I'm don't think it works on the lock screen and some of system settings screens but everything else seems fine.
