As your light sensor is broken, you set the screen brightness settings to manual (disabled auto-brightness) and maximum level?!
If the screen is still not "lighter", then check that you don't have installed a screen filter app, which could also change the screen brightness.
And as you don't post your ROM and kernel version, in some ROMs/kernels you can change the screen brightness too, and this may overwrite the settings in "normal" display settings menu.
If you had a custom kernel running on your phone before, you should wipe cache (and Dalvik cache) in recovery mode.
If you already checked everything and screen is still darker, then it could be a hardware issue.
In different SGS2s, different hardware components were used. And the broken light sensor as a damaged hardware component may have influence for the screen brightness too.
Enough
You have two threads already on this subject. Here's one and this one. Do not make a fourth.

I've seen that the Xperia S has light ambient sensor, but i cant find the configuration to enable auto screen brightness.
Any idea how can i enable it?
I don't think there is a setting for it there wasn't on my arc either
hmm i have read that the auto brightness function is enabled by default, but i dont notice any brightness changes when i enter to a dark room or go out in the day, auto bright function doesnt seem to work.
Anyone can confirm this?
On my SGS2 with CM9 it is under Settings --> Display --> Brightness.
I dont know where it is under Sony ROMs, but somewhere around Display or Energy Saving maybe it has to be, I couldnt imagine that Sony would take out this...
If you want to test it you could light with a lamp direct in the sensor or cover it, then it has to change the Brightness.
you set the lowest screen brightness you want, then the phone does the rest

Exactly. It works just like the iPhone this way.

Well, if you manually set the brightness to the lowest setting you are gonna get a dark screen. Obvious thing is obvious.
I've recently been to Sony Mobile's headquarters in Redwood, and I got all the details about this explained to me.
The way it works, is that you can manually set a "preferred level" of brightness, and the phone will automatically vary this setting but not stray too far from it. The default value I believe is 50%.. I don't have exact numbers for how much it will differ, but the auto backlighting is there.
I also asked if Sony will add a manual override to this setting in a future FW upgrade, and they said that they might
SEARCH before you post!!! Already discussed (and how to enable it)
It's enabled via the screen brightess toggle. One option is Auto.

Odd issue i've got on my Z Ultra, easy to replicate by doing the following, bring up chrome, click the address bar, with nothing entered in the text box, but then type something, an the white box drops down, with search suggestions, I can see the brightness increase on my screen, clear the text box, brightness dims back down very easily by staring at the keyboard while this is happening.. is this a hardware issue, or software related? anyone else notice this? very strange. its like more white content on the screen, the brightness kicks up.
Seems normal from what I notice. If it bothers you, turn off auto brightness.
It's part of Sony's dumb LCD optimization gimmicks
It's equivalent to auto contrast used by TV's and LCD computer monitors
You'll notice your brightness goes down when much of image is dark, and you'll notice the brightness goes up when viewing white images
This doesn't happen on custom roms based on Aosp (like slimrom which I use aand prefer)

Wow this is crazy, I just noticed my phone doing this a couple of days ago, and here's this thread. While I do find this dimming "feature" a bit irritating, it's hard to complain about the screen on this device. It looks so damn good.
This feature is called optimized backlight and you could disable it in settings on android 4.2.2 (correct me if im wrong) but since android 4.3 sony removed option from settings menu and they enabled it by default, unfortunatly you cant disable it unless sony returns this option in new android version or if you downgrade to android 4.2.
Sorry for my bad English
I am using z2 about 10 monts. Today i feel when i put mobile full brightness i observed some wave running from top to bottom. Specially observed when open NDR utility and es file explorer. Before appearing the both applications interface waves appear for instance. I am worried is it ok or some problem. And also today observed brightness bright more autometically, althoug i am on full brightness. Any help suggestion Thanks in advance
I've noticed the brightness change on its own too sometimes. I always use full brightness (adapt to lighting conditions disabled) and randomly, I'll notice my screen get brighter or darker sometimes. It's completely random, not sure what causes it.

Omg I thought I was the only one, My brightness is set at 100% when I quickly unlock the phone I notice a quick dimming on the screen even though it's at full brightness...

Yup I have the exact same thing. Not sure if others have it as well, but as far as I'm concerned, it's normal (I hope)
Hi!
I have the S6 edge since yesterday and I noticed that auto brightness does not work.
Testing the senosr via a sensor read out tool, it actually detects brightnes levels well (as far as I can tell).
However, if I turn on my phone, it is first super dim at first. When I expose it to a flash light, the screen turns brighter and eventually maxes out. But it does not turn back to normal brightness levels once I remove the light source. Sure I can adjust auto brightness with the slider. But it is then much brighter (with same light conditions in the room) as when I truned on the phone...
Only if I turn off auto brightness, the screen reverts to the setting I have chosen...
If I turn auto brightness on again, it is as bright as with flash light exposure...
What is going on here?
Does anyone have an idea how to fix this?

I have the same problem. Already talked with Samsung and ATT. They want me to change the phone.
Ps. It seems the problem only persists in S6 edge not in S6. But I also found that other android that run lolipop 5.01+ have the same issue too. And right now, I use the app name velis auto brightness to fix this.
I will try to change the phone by this week and update you.
Hope this help.
I have started using an app called Lux. And it has no problem adjusting the brightness. The sensor clearly works fine as it can always displays the brightness detected by the sensor. So it has to be a software problem.
I could imagine that a hard reset could fix the issue. But right now, I do not want to go to the hassle to restore everything
Let me know how the new phone works. :highfive:

The hard reset did not work, I already did it.
I will update you again once I change or test the other phones.
I went to the store, and both S6 and S6 edge in the store all have the same problem, so the exchange it may not solve the problem.
I think this problem may be a software problem or an intention from Samsung/Google.
I will try to use it in couple days. If I cannot bear this, I might return the product.
Hope they will have OTA update soon.
Got this too.
It's really anoying.
I really hope there will come an app like on older Sammy's that we can set and adjust our own brightness levels.
But I'm not expecting a fix from Samsung tho. They have proven again and again they are unable to fix their crappy software. Especialy if it's a minor bug like this.
So anyone wanna buy a rooted hardly used S6 Edge plus?
I have a 2 years old Samsung Galaxy S9 plus.
Sometimes, when I lower the brightness of my phone or the brightness goes down on low light conditions as Adaptive Display is 'ON', a bright green color keeps flickering. If I increase the brightness again, it will go.
I did whatever the internet told me to do. I factory reset the phone, enabled the 'Disable HW Overlays' in Developer Options etc. Nothing solved the problem.
This happens only very rarely. Most of the times, my phone will be fine. Very rarely, the flickering occurs.
I took it to the nearest Samsung service center and they told me that i may have to change my phone display. It costs around Rs. 19000.
My question is, if it is a display problem, why it happens very rarely? I want to make absolutely sure that this is a display problem before replacing the display.
Will this cause because of any other issue?
@jayeshbabuav
Do some troubleshooting to make sure the flickering is a problem with your Android’s software, instead of hardware - here: the OLED display. I think it has to do with device's GFX driver - keyword: Screen refresh rate ( Hz ). If refresh rate is too low then flickering occurs because there aren't enough updates per second.

Don't have a Samsung Galaxy S9 Plus phone, hence can't tell you.

is there any chance this is a battery issue?

If this were the case, the screen of a mobile device or laptop being on low battery would flicker all the time. Think about ...
As said: It's a misbehaving app or phone's GFX driver that causes screen flicker.
hey, i've just had this problem too yesterday, with my xperia xz3 which has an oled screen. It flickers like crazy on low brightness, and gave me a CRT like effect when i turned it on or off. have you found the fix to it already? or maybe you changed to a new phone?
