Hi there, just wanna mention that i did search the forum, but didn't find an answer, just to be clear on that.
So, yesterday i got a desire, switched from a wildfire which i had for 2 months, there is a bit more power and fun to be had with a desire.
But as with the wildfire, i noticed that the auto brightness function isn't doing so well.
If i get up at night and it's all black in my room, the screen is way to bright, i have to use the power control to bring it down, but the downside is that it disables the auto brightness.
Is there anything that let's you tell auto brightness, if it's pitch black, brightness should be this low and so forth?
I've rooted and flashed with leedroid.
I'm running LeeDroid and I don't know if it's recalibrated or what, but it's definitely better than with the stock ROM.
Edit: Just saw I didn't read your post well enough and you've got LeeDroid as well, so my answer is not too helpful... sorry...
The Cyanogen ROMs have settings to adjust brightness.
This was one of the things that annoyed me about the desire.....so much that I decided to fully root this thing and do things my way lol
So I removed the stock ROM, Radio, HBOOT and Recovery and flashed some custom ROMs and now automatic brightness works JUST FINE ^^
Edit: Does leedroid come with automatic brightness settings?...hav u checked under the Display settings? becuase most of the ROMs that support automatic brightness needs to have it enabled and setup to work properly

Well, yes leedroid has automatic brightness, but as i mentioned, it's still too bright at night, i want to tell auto brightness that if i does not detect any light, it should turn the brightness as low as possible and so forth.
Do you turn the brightness down with power control you disable auto brightness and have to manually enable it again.
Even tho there is only one sensor, instead of having a preset value for different amount of light detected, it could be smarter.
Ex. auto brightness is on, it's dark, you go into brightness and turn it further down, phone asks you if you are turning it down because you think it's too bright, you click yes, phone learns that you want lower brightness when it's very dark, you click no, phone does nothing because you had another reason for adjusting brightness.
The next time, phone remembers that you want low brightness when it's dark, so you don't have to do it again.

Hi Guys,
So I finally got the desire after being with an iPhone for the past 18 months. Lovely phone so far, even if it feels a little 'work in progress' in some depts.
Anyways!
Have any of you with the phone enabled auto brightness? Does it work? When I jump into the settings to enable it it seems to kick in (once i tick the auto brightness checkbox) but once I actually hit OK to save the changes the screen brightness shoots up again and then doesnt seem to react to ambient light.
weird.
I am running the t-mobile android (uk)
Yep, I have the same thing, glad it's not just me then!
I don't think I've seen it adjust by itself at all...
It works for me and I have seen it adjust.
im not sure really if it works because it always seems the same? i have changed it to 30% now which is just acceptable and we ll see if it gives any battery boost

That's the idea, auto brightness adjusts so that the screen looks the same brightness to your eye at any light level. When it's dark the brightness decreases and when it's light the brightness increases thus you see it as thee same due to the way your eye is already adjusted.

yeah Lol exactly, thats the whole point of auto screen adjustment. if you are indoors all (or most of) the time like me than keep it manual to 30-50%. otherwise leave it auto
Mine works a treat the only thing i do is when i go out the house i turn the brightness to manual and put it on full, as this is the only bad side to this phone the led does suffer in direct sun so full brightness is required.
I haven't seen any change in my screen brightness, whether in full sunlight or middle of the night in a dark room!
Is a bit annoying, would like to know if it can be fixed or we're waiting for the next firmware...
Where's the sensor ? With the Hero, placing a finger over the top part of the phone tricked the sensor but it doesn't seem to on the Desire. Interestingly though, there must be something there, the way the screen flashes up when you remove the phone from your ear

Works fine here
It seems that on my Desire the only time the automatic brightness actually tests the light is when I unlock my screen.
I can actually see the brightness change then, but if I switch lights on/off while it's already unlocked it doesn't automaticly adapt to the light.
I only checked it through the Android SDK using Dalvik Debug Monitor and the phone certainly did continuously check and correct screen brightness according to it. Visually, it was too difficult to discern what was happening and when due to my own visual limitations when the amount of light changed.

I just installed CM7 stable version yesterday, everything goes smoothly except for the autobrightness function. Whenever I turn my screen on, the first time it always very dark, although perceivable but it's like the autobrightness is broken. Yet, when I immediately turn off the screen and turn on again, it's bright like nothing happens.

try turning off "screen off animation" it will fix it. it a known bug.
please refer to this thread Numerical explanation of the CM7 automatic backlight settings
Byrong does a really good job explaining what the auto brightness settings does in CM7.
By default CM7 auto brightness doesn't work very well, you need to configure it to your liking using the options described in that thread.
Use the status switch toggle the autobrightness!
Hi everybody, I recently updated my Eonon Androud HU to 5.1.1 using the first 5.1.1 custom ROM listed here. The DSA Prerooted ROM. Thus far it's been functional and fits my needs over the Malaysk ROM. However this ROM has some sort issue with it automatically dimming the screen to low, even though it's been set to 100%. When sliding the brightness slider to 100, the screen will still dim on its own, regardless of the adjustment still being set at 100%. I have gone through all the settings and found nothing that can help me. The display submenu only displays the option "Brightness". Which is just the standard slider to adjust the brightness. There is no option for Auto, Low, Bright, etc.
I've downloaded some apps to control the brightness to see if that would help, but something on this ROM is overriding any brightness apps from working. I even tried installing an xposedMTC module as it had an automatic dimming option, hoping to deactivate it completely but no luck. The way my car works is my headlights have an automatic DRL. When I turn my DRL's off, the headunit seems to activate it's full brightness, until I turn the automatic light control back on which turns on my DRL's, then the screen goes dim again. It's as if the headunit is going by the whole "Oh your headlights are on, it must be dark outside. Let me adjust the brightness to low for you".
Any help would be appreciated. I hope it's a simple fix. Thank you!

That's one of the main differences between Malaysk and DSA. DSA told me look out the window and figure it's night time. Secondly he told me to go to max at least two or even three times in a row. It will then STAY 100% bright till you reboot.

Whoa, thanks for the quick reply and useful information. Is there absolutely no way to bypass having to do that method? As that would be a chore doing it multiple times after exiting and entering my car multiple times a day. Maybe a simple build.prop edit possibly? Just naming ideas.
There is... Mtc manager has settings in it for brightness settings due to time. You can turn it off there. This didn't work for me so I went another route with changing some file. Its all detailed in the thread as to how.

You could disable brightness control entirely or just alter the brightness levels.
It's in file /system/etc/install-recovery.sh - at its end, comment out all 14 lines after comment line reading "#Brightness control (last, always)", in order to disable the algorithm.
OR, change line reading "nb=5 ### Night Brightness ###" to a different value for the night brightness (nb), eventually equal to day brightness (db, on next line).
Use a root explorer, or edit a copy of file on PC (with notepad+ if on Windows) and copy it back - with a root explorer or manually, if you can. File mode: 0755, owner & group: root:root.
If script /system/etc/install-recovery.sh gets "damaged", you must reinstall the firmware, but with NO wipe all, so fairly quickly and no loss of settings and apps.
Editing of script could also be done with @devilsoft app (with a name I can't recall).

Hi @brian117 !
In fact, there is a simple fix I found lately.
You need to enter factory settings first.
Go to SETTINGS -> Factory settings -> enter code: m123456
When you're there, go to last page, and tick the "Key light" option.
Now press "Apply" and "Exit". Confirm reboot.
It worked with me - now the screen has full brightness regardless of the car lights on or off (in Poland we need to have the lights on whole day, as well). Now you can use a software dimming, like MTC to auto dimm the screen according to actual day time. I did this. Works like a charm! (I set dimming after sunset to 75% 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.
