The Auto Brightness Works? - Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot

I wanna set auto screen brightness for my kindle fire hdx 8.9 (14.3.2.1, unrooted). However, I found the screen always staying at the maximum brightness if I turn auto brightness on.
Then I used app like "sensor readout" to test the light sensor, the readout changed according to surrounding light. Sensor no problem.
So I conclude the auto brightness function doesn't work on the kindle fire. As can be seen this system is really buggy: for example, even I clear all the notification, there still number in the notification bar...etc

Same thing happening to mean. I wonder if we call support they will downgrade us to a older version

Since newest ota, KY screen dims as if it is going to sleep. This happens when using the tablet. Not idle. Goes dim for five seconds and comes back on its own. I use the auto brightness on feature. Weird behavior.

I'm sorry, they don't do that, however what you can do is reset to factory default, this might fix your problem.

light sensor

hi all, I noticed that light sensor doesnt work properly, when I go from dark to light area, the brightness increases but when I go from light to dark area the brightness wont decrease, on honeycomb it worked properly, anybody else experiences this problem?
Same here, it goes bright but does not decrease.
I use the app https://play.google.com/store/apps/details?id=rubberbigpepper.DisplayBrightness&feature=search_result#?t=W251bGwsMSwxLDEsInJ1YmJlcmJpZ3BlcHBlci5EaXNwbGF5QnJpZ2h0bmVzcyJd
make an invisible slider on the edge of screen to adjust brightness.
is there any way to make it work properly?
Don't think so. Its pretty much unusable now.

There are lots of negative comments about light sensor, but i have to say it works well to me on ICS. Could be possibly massive amount of defected devices.
Lightsensor doesn't work for me either - too bad, hope it will be corrected.
Perhaps it's because I'm running ICS "General Channel".

Do the sensor dim the light in the same session for you?
Here it turns up the light but not down again.

Same here, adjusting upwards works fine, but it doesn't adjust downwards in low light conditions.
I have tried two apps that turns the light down again, custom auto brightness and lux auto brightness.
One small problem. The pad will crash on pattern unlock after sleep. I Also the light sensor will not work s after wake up sometimes.

I'm guessing no one has had any luck with this issue but I figure I'd necro the thread anyways. My light sensor sucks also. I used 'Android Sensor Box' to get the values coming out of the sensor. It only displays either 40 lux or 280 lux which is obviously not right. This is on Cyanogen 9, stock t-mobile ICS and the rooted international gingerbread(can't remember which one exactly).
So I was wondering if anyone who owns one of these has ever gotten a sensor value that makes any sense.
thanks
nope,
I use instead display brightness https://play.google.com/store/apps/details?id=rubberbigpepper.DisplayBrightness&hl=no
create an invisible brightness slider on theedge of the screen.
Try using custom auto brightness with the auto brightness on (there's a setting in that app that disabled the system auto brightness at screen on. Turn it off).
The original kernel only recognized 3 light levels. If you use bart's kernel it will recognize 6 levels.
Yes, I think there's a software problem because both app (lux and cua) crash hard in HMP, but I don't think fixing it is a priority.

How to use custom auto brightness without crashing the tablet.
There are 2 options that should be followed, other settings can be adjusted to your liking.
1. In preferences, Check Use pulsed sensor mode. Basically this option will make the app read the sensor itself instead of listening the sensor value given from the system.
2. In advanced preferences, set the sensor update speed to either half sec or 1 sec. I tried normal, but the app won't read the sensor value, so probably the slow normal maximum setting only works if you get the sensor value from the system.
You can set disable system auto brightness. I recommend it before because the setting was a "hack" which was making the system read the brightness value thus the app can get that value. Right now it's recommended that you check the disable system auto brightness.

[Q] Full Brightness waves

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.

[Q] Auto brightness not working

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?

Minimum brightness

You don't want to give your significant other yet another reason to yell at you while you're reading XDA in bed. Rate this thread to express what you think of the Samsung Galaxy S7 Edge's display minimum dimness. A higher rating indicates that the display can get extremely dim, ideal for reading in very dark environments.
Then, drop a comment if you have anything to add!
I don't have on auto brightness or any power saving features on yet my display brightness seems to have a mind of its own. I can be in a dimly lit room and have to put my brightness slider past the halfway mark just to get decent brightness and the always on display will be so dim it's barely visible. Other times I could be in a well lit store or outside and the display will be very bright even with the slider nearly all the way down. It also seems the always on display may get brighter the longer it's on but it starts out very dim even if my brightness is cranked up. I really don't know what to make of it. Sometimes the display brightness seems way worst then my nexus 6p (not saying 6p has bad brightness just using as a reference cause most reviewers claim the brightness on note5/s7 is a bit brighter.) Other times the quality seems better then my friend's note 5.
Adaptive brightness? Sure sounds like it.
I am disappointed it does not go low enough like all android phones tablets etc. I read books in the Kindle app in bed and my iPhone or I pad can go very low brightness but all the android gadgets I have cannot they are always too bright and annoy her. I thought this could be the one but I guess not

Install LUX Auto brightness app and it should solve your problem, in fact you can set it so dim that you can hardly read it.
I find the always on display to bright. Is there a way to dim it a bit?

I totally agree with that, when you cover the sensor the brightness is way better.
It should be part of the environment, now it's more like "HEY LOOK AT THE TIME" kinda distracting

Yeah haha. The funny thing is that the "night clock" is perfectly dimmed. Wished that there was a setting for the AOD (always on display) to have manual brightness controll. And of course app notifications. Which the edge display can show, but the AOD can not. Strange decision of our Sammy friends.

Exactly, that would be perfect, I tried using AOD at work today and it's so distracting that it's actually worthless now. I also tried the night clock at work and it looks great, it doesn't bother me at all and it's very handy. Hope samsung will update AOD because it can be very useful.
But in my opinion the overall (auto) brightness is too bright, when I dim my screen it automatically brighten the display up to what it thinks it is the right brightness compared to the environment . With my previous phone (LG G2) it changed the auto brightness to the user preference.
You can fix this issue, set brightness 100% and reboot.
Hi guys, I noticed right now that if I switch from an high luminosity environment to a very dark one, automatic brightness remains the same and I have to uncheck and check again the "auto" option on notification bar. Other times, in same conditions, it adapt the brightness after some times instead of immediately. Dose have my phone problems?

This is to prevent the display continue changing brightness, it does change but it has a delay so your screen isn't flickering bright, dark, bright, dark.

This has been fixed with the update that came out this week #yay! It's now changing automatically, not as distracting anymore :highfive:
I noted that when I turn on the screen I a low light environment, it has a fade before the screen completely turn on, like a fade effect. I did some tries and this happen only in low light condition. Is this normal?

Yes, but if I put the phone orizonthal (for instance I put I on the table) the brightness change immediately. Why is that?

Do you have MM or Nougat? I noticed the same in MM but it works significantly better in Nougat.
The problems some of you have ... seriously? ?

The screen is way too bright and there's no way to adjust it when outdoors

So when you're outdoors, even if it's overcast there's no way to slide the brightness down (It auto-snaps to full brightness) even though it's not needed.
I have situations where i could easily use half brightness but my phone forces auto max light
YES, I know i can disable auto brightness completely, but that would not be convenient.
Any fix for this?
I use an app called Lux. Tons of options with it.

Hmmmm, Im not sure how it works but it does have an auto mode which you can tweak on the fly.
I have noticed that also. It also jacks up the contrast to make it easier to see.
It makes pics you took look terrible when viewing them outside. I had to learn to NOT delete them until I check them indoors. I assumed some pics I took were crap at first, but it was just the jacked screen contrast that made them look bad.
On my S9+ in bright sunlight it happens that not only something happens to the contrast and colors (eg. reds become somewhat pinkish) but also black elements on screen start flickering/smudging while scrolling. It looks like the device turns into some sort of brightness boost mode.
Does anyone else experience anything like that?

That's exactly what happens to me. Also if you slide the screen you can see how it the colors are totally distorted.

Check out the screenshot. There's an option to enable brightness slider in the notification bar. Becomes easier to adjust brightness just by sliding down the notification bar.

Did you read what the problem is? outdoors it snaps to max no matter what. (Unless not in auto mode)
Any solution for this problem?
Turn off auto brightness when outdoors..
Guys I've noticed that even if you turn off auto brightness go out in the sun and turn the screen up to max manually,it will kick up into super brightness mode or shine a led light at the sensor when indoors simulating the sun,just like it does with auto brightness on.sammy really want us to get burn in I think so we have to buy new screens all the time?

Never had a screen burn in on a Samsung phone. Don't worry
Guys, idk if this is a S10 only feature (or Android Pie), but when I'm on that situation, if I lower the brightness slider and leave it there for a second or two, the brightness will actually stay down and not jump back up again. Worth a try.

After the S9+'s update to Pie some of the old settings get copied to the new OS, but if you don't go into the settings and check, things might not be configured correctly - I had to choose a different setting and then choose again what was previously selected to ensure that it was written into the Settings correctly.
With the new update the "Automatic Brightness" applies to the AOD - see here in this screenshot, my search of the Settings for the word "auto brightness", see what comes up in attachment #1.
What you need to do is go to the "Adaptive Brightness" and turn it on, then manually adjust your brightness under a few different conditions (EG: Indoors lights off, outside and overcast, and bright sunny day). Now your phone will understand what setting you want for different conditions and automatically adjust the brightness based on lighting conditions, see attachment #2.
The "auto brightness" is now used for the AOD, and has nothing to do with brightness when unlocked. The reason it "auto snaps to full brightness" is likely because previous settings were just copied over after the update and you haven't setup (and trained) the new "Adaptive Brightness" for various light levels. The AOD has both "Auto Brightness" and double-tap the clock to adjust AOD brightness.
