(Q) Auto Screen Brightness

Is the screen brightness supposed to drastically change when auto brightness is enable. I've been playing around with it and noticed that when auto brightness is enable the screen will drastically change in different lighting conditions (with a couple second delay) For example, ill walk into a darker room the screen will get a lot dimmer after a couple of seconds and v-versu. The reason I asked is that my eco 4g would gradually adjust to point t where I didn't even notice.

I've noticed it rapidly changing like it can't decide a few times, and overall it's a bit too dim outdoors. Coming from an Evo as well and I never noticed it changing either.
Just going to keep an eye on it, not a huge issue for me. Might see if there's any way to override and manually specify the auto brightness thresholds.

There's a second setting called "Auto adjust screen power" further down on the display page - it could be that. It's some sort of thing that analyzes what's actually on the screen and tries to adjust for it.

I think it may just be a samsung thing. I have a Galaxy Tab 7" and I noticed that it was doing this as well, and it drove me crazy. I just went into settings>display>brightness and turned it down manually to just under halfway indoors and if I know Im going outside, i turn it all the way up.

Ive also noticed thst it was auto adjusting even when i had it disabled which was probablt the "power adjustment" thing... But once i caught it turning the brightness down to "prevent overheating"!?

Really?! Thats bizarre. I wonder if it will constantly have the screen down while wireless tether is running.

Thanks. I also have auto adjust disabled. Since others are seeing it then I assume its a Samsung thing. Ill wait to see if others confirm. BTW this may just be me being a geek. I notice every little thing. The other is that the buttons at the bottom of the phone aren't as sensitive as the eco.

A tip I read somewhere but haven't tried yet is to turn auto brightness off and when you do, hold down on the notification bar (don't pull it down, just hold a finger on it) and slide left or right to adjust brightness on the go. Not for sure if it works but give it a try (I'm chargin my phone while it's off now so I can't yet).

It works. I just tried it. That is pretty cool!

Worked for me too. That's great. Thanks. Where did you read that? Are there other tips?

This was a feature in the original epic as well. It is pretty cool. I just use this to change brightness . The only time i change is when i go out in the sun.

Can't remember anymore besides the screen shot one which has been mentioned. Tap home and the power button simultaneously. Also can't remember where I read it.

I would honestly say its a combination of things BC I have used roms where its totally obvious (on froyo) where on others its completely impossible to notice the change.

They kept the good features from the Epic. I like the feature in "Contacts" where you can swipe right on a contact to call them and left to send a message as well

I've had the brightness at the max, and turned off the Auto Adjust Screen Power option. Just while browsing XDA the screen dimmed, and when looking at the brightness setting it states "To avoid overheating, maximum brightness has been reduced.". This has happened at least three different times.
I'm hoping this isn't a serious issue. Have you had it do that multiple times for you as well?

Auto-brightness-once it goes up it doesn't come down

On my nexus, my auto brightness is not working right. If I take my phone in bright light, the screen brightness goes up. However, if I move away to a dim place or cover the light sensor, it doesn't dim the screen. Its like its stuck on that higher setting till I turn the screen off and on. Of course we have the very low brightness issue also, but this is different. Can anyone try this on theirs' and see what happens?

Same here. Minor inconvenience. Last phone did it also.
Sent from my Galaxy Nexus using xda premium

I've never had a phone other than an iphone 2g that did this. Its very bad for battery life. I mean, you would be using your phone in bright light and then move away to a dim place and expect the screen to go down in brightness to save battery. But its but working here this way.

guys, especially the new Verizon owners, do you all notice the same thing on your phones?

Please can someone test this out? I need to see whether its a defect on just my phone or whether its normal behavior with the Nexus . Thanks.

Great, but it shouldn't do that. It should auto adjust on the fly. I saw it functioning fine on the Note I had. After the patch, does this work normal now?

OMG I've just tested my iPod Touch 4th Gen with my LED torch.
It behaves exact same as the Galaxy Nexus
Once the screen brightness has been boosted up, it won't go down until I switch the screen off and on again.
What the hell is this? Is it a kind of function but not a bug?

Yea, my old iphone 2g had worked the same way. Once it goes up, it doesnt come down. I've never had a android phone that works that way. All of them go up or down dynamically as needed. I'm sure the change is something new on ICS. Gingerbread & older OS did not do this, example: The Galaxy Note I had before Nexus would dynamically shift. But not the Nexus. On the Nexus, I have to turn the phone off then on for it "sense" the dimmer lighting to decrease the brightness.

Or simply not use auto-brightness.

You could do that, but the intent of this thread was to highlight an obvious flaw with ICS. Im sure thats how google wanted it, but why?

Did anybody find the patch and does it work?? I searched the dev section and all I could find was patches to increase the light levels of the auto brightness, couldn't find the patch or a fix for the auto brightness not dimming. If someone could link it or point me in the right direction that would be awesome

Bump
Nobody was ably to fix the issue of the screen not dimming???

Same here on 4.0.4, I find it very annoying. A friend of mine now uses AOKP MS5 on his device, which dims correctly (as I think of what "correct" is).

Stock android has always been in this way iirc...
Only phones not running an aop Roms (like samsung) lower the dimm...
CM9 has a specific option to enable backlight dimming and always had (yes, in gingerbread too)

Im the OP of this post, turns out most of the custom roms have an option under display settings called decrease hysteresis that allows the screen to dim. I am completely satisfied now.

Auto brightness too dark?

I used to use a galaxy s captivate and now I'm on the galaxy nexus.
One thing I really liked about touchwiz was how you can swipe across the status bar to change the brightness.
Now on my galaxy nexus I just put it to auto brightness. But I think its usually darker than how it should be.
Is this how it has been for android all the time? I never used auto brightness in the past so I'm not sure if I'm the problem or if its the device.

I agree. It's too dim for me to use.

I leave mine anywhere between 35 and 45 percent and its perfect. If I'm in direct sunlight I crank it up to 100%.
Sent from my Galaxy Nexus using XDA App

I can use auto brightness fine, can even use minimum with no problems. However I set it to 50% so that I don't get some of the colour changes that amoled is prone to.

I'm worried about my auto brightness as it doesn't seem to work at all. Standing in a dark room and then turning lights on bright makes no difference. On 4.0.1.

We should ask for a change request to Google.

Used that fix on Android Revolution HD Rom, worked perfectly.

any way to lower the brightness of the led notification?

I love the led notification, nothing like waking up in the middle of the night and looking over and knowing you don't have any notifications because the light isn't going off... but when I don't need a flashlight BECAUSE it's going off it gets annoying... I wanna be able to go to sleep if I'm ignoring it; yet have it there to know I have things to look at.

Just turn it off???
Sure its nice to know if you have a message from afar but really? One of the first things I did when I got my GS3 and Note 2 was go into settings/display/LED Indicator/and unselect all boxes.

i don't think you can lower the intensity, but you can turn off the notifications and us an app called NoLED. it puts a notification on your screen instead. since OLED only lights up the active pixels the drain should be any more than the notification light. i use it with my sammy droid charge that has no notification lights.

Why not just go into settings and turn on Blocking Mode?
You can set the time frame it's active. It can keep led off, notifications, phone calls etc. You can change the settings for it.

From what I know, it remains in the notification panel, as long as Blocking is turned on.

Yea. I know what you are talking about. I saw that on a galaxy s4. It is an auto brightness that allows you to adjust the brightness (half auto half manual). I want that feature too but I dont think tmobile galaxy s4 has it.

You also can't the brightness once you're below 5 percent.

You can do that useing this app from the playstore "lux auto brightness". I used it for a very long time on my old samsung gs3. When I really want to conserve on battery or want my screen much dimmer than stock brightness,that app does it. You can manually link your prefered brightness for each step It increases also.
