Froyo FRF85B Ambient light sensor only working one way

Hi, I am new to these forums and bought my nexus one one month ago. After the recent froyo OTA my ambient light sensor only brightens my screen. If the light dims and even when there is no ambient light it fails to lower the brightness and will stay bright forever.
I have tried using wipe cache and a complete factory reset from recovery mode. After this I even reflashed the official froyo OTA which is found on these forums. I am a new user and can't post links yet.
This is an AT&T, Rogers/Fido phone and it is stock. Can someone please confirm and see if this ambient light senor problem is an actual bug and exists on other phones. If not then what can I do to fix it as it was working properly before.
Yes, I have FRF83 (T-Mobile version) and that seems to be the case for me, as well: the display will only dim when I first hit the power switch to bring it out of standby. It will increase the brightness when the ambient light becomes brighter, but not vice versa. I hadn't really noticed it until now.
My suspicion is that this is intentional. The original software on the Nexus One generated a lot of complaints that the screen brightness changed unpredictably, that very minor movement of the unit would make the brightness change repeatedly. At least this way, the screen is guaranteed not to be inappropriately dim, but you will still get most of the power-saving benefit when you turn the unit on in a low-light environment.
I too believe this is intentional, I'm sure I read about it somewhere.
Alright, thank you for your responses. It would appear that they did this intentionally. As long as it's not a problem with my hardware only, I just got worried.

Screen brightness bug under diffused sunlight (as in when put on a car mount)

I use my phone regularly for navigation with waze. One thing that is really annoys me is that when it's really sunny and bright outside, the phone display dims down to minimum brightness level. Brightness doesn't change even if I touched the screen. If I cover up the (brightness sensor?) on the top left part of the phone, the screen is bright again.. It seems like diffuse sunlight is causing some sort of weird thing with that sensor. I tried to point a flashlight directly on the sensor and the display brightens like it should. Only when there is diffuse sunlight, it does this weird behavior.
Anyone else seen this?
EDIT: I am on 5.1 leaked soak test. I am pretty sure I had the same thing happen when on stock 5.0
I've had that happen on other phones by different manufacturers as well. Very annoying, the only fix I had was to just disable auto brightness.
Such a good feature, but haphazardly implemented it seems.

[PIE] Adaptive brightness issue?

Good evening,
just wondering if anyone else has issues with adaptive brightness after the latest PIE update? Since the update it changes the screen brightness during low light conditions from semi-low to low without any reason. And in normal light conditions it sometimes gets way too bright. And it doesn't modify the screen brightness in small steps but in one "big" step.
Btw: I did not wipe my phone before upgrading, maybe that's part of the issue.
yeah same issue here. phone seems to wake up in very low brightness mode randomly?
same here.

You will have to go back to the display brightness and adjust to the level you like, then subsequent light condition will then be adapted to your new value.
Hope this helps.
Same here. And I did full reset, after Pie upgrade
It needs some time to finish learning, Adjustable brightness Android 9 feature is now AI controlled. Google it.

Auto brightness issue

Anyone else having issues with auto brightness after the pie update? My phone sometimes does not change the brightness automatically when I move from a bright to dark environment until I turn the feature off and on again.

go to a dark place slide the brightness to desired level. no go under a bright ligh then shut it off and see.
Just tried this. Sometimes it works and sometimes it doesn't. When it doesn't I still have to turn it off and on again for it to work again.
it's the new adaptive brightness..... you set the desired light in each situation over the next few days using the slider (adaptive ON)... it will adapt to your preferences in different situations.....

Thanks I'll give it a try.
Doesent work with my note 9 Pie...
I Flashed ota from 8.1 and later i flashed back to 8.1.
Later i flashed again 9.0 but this time not via ota. I flashed it clean via odin.
Same issues with adaptive brightness :
1. It does NOT learn my pattern. This means : I turn it darker. And later in the same spot it turns it back to the middle... Over days and days the same.
2. If you turn on the camera-app, it turns the brightness high. That is okay, i like that. But if you turn the app off, and if you are too fast for the system, it stays enlighten untill u lock ur device !
Oreo :
1. It learns my pattern from day one (!). I turn it darker. Later on the same spot : It stays dark ! Perfect
2. Turn on the camera app and it got brighter. Nice, like Pie, right ? Yes, but turning the camera-app off and swiping it instand away from recent apps, it turns imediatly back to the normal brightness, it learned from you !
I hate it ! Pie does not work fine with my brightness preferences !
Other user in other forums have the same issues with pie...
And there is no way around. I tryed it all. Every option and every possibility. Iam not a beginner in android.
I gave the adaptive brightness a cance of 10 Days, but every day it learned nothing. And the Camera problem...Turn the app on and open recent apps and swipe the camera away and then go back to home. If u do it too fast (I do it every time on every phone with MY speed) it stays bright like u throw it in the sun
Same here adaptive brightness has gone bonkers for me after pie upgrade. Just like you it works when it wants to. Really frustrating.
So please guys, tell samsung that problem in the members app.
The users in our german forum did that, and i did that too.

Screen brightness on replacement is poor

Hi
I recently had my Huawei P30 Pro fixed and the screen brightness is terrible. When outside, even if cloudy, you struggle to read the screen.
This was definitely not the case before I had the screen and battery replaced. (was 3 years old, and the screen had some moisture in it from a very rainy hike). The phone shop (not Huawei, as outside of warranty) said they used official Huawei parts.
I barely notice a difference between brightness halfway and brightness to full when I adjust it manually. It doesn't even detect that it needs to put the brightness on full automatically when I'm outside, which is strange.
Any ideas?
this is interesting. I have been having this same problem as well. With mine, if I wake it from lock in the sun, it will work perfectly, super bright and readable, but only for like 15 seconds, then the brightness slider goes down to about 75% and it is almost unreadable. If I try to manually put the slider back to 100% there is no change to the brightness. Very similar to your problem, there is no difference in brightness between 75-100%.
If i lock the screen for about a minute and open it back.. boom 100% fully bright for another 15 seconds.
Mine started giving this problem before I had to open it up to change the microphone, so I'm not sure if it's happening with firmware on only certain panels? This has been happening to me since July 2021, so no firmware releases have fixed the problem.
