actually the screen is kind of shock me because 30% brightness under sunlight the screen looks great.

You can test, and make sure, that it actually have the ambient light sensor through the Service menu (Dialer-> Dial *#*#SERVICE#*#*), then go to Service Tests, then select Ambient Light Sensor.
Put your hand or change the ambient light, you'll see it's there and it really does work.

SEARCH before you post!!! Already discussed (and how to enable it)
It's enabled via the screen brightess toggle. One option is Auto.

How to enable auto brightness on Xperia Ray?

I found that Xperia Ray have Ambient light sensor from the white paper, but i can't use it on stock roms or CM7, can someone enable this?
this is the link of white paper
http://dl-www.sonyericsson.com/cws/download/1/997/193/1308295710/ray_WP_1.pdf
thanks!
Good question!
I also found in the whitepapers that the Xperia mini pro (sk71i) has the same ambient light sensor but when I check with android tools like "Sensor List" the only thing that could match is the Proximity sensor. That one goes from 1 to 0 if you get close to the top (blocking the light?).
APDS9702 Proximity
The sensor is enabled by default
how? i can't feel that
With my HTC Desire Z I had the "auto brightness" option. On this one I don't. Are you sure it is enabled? Do you have any clue what sensor it would be in the list of for example android app "sensors list".

As of Stock Rom 2.3.3 and 2.3.4 there is no 'auto brightness' option.
But the ambient light sensor is always working.
If you take it outside in bright sunlight, you will notice that the screen automatically gets brighter. That's how you can tell the sensor is always on
I assume they haven't put auto brightness in as a feature because maybe some people want to save battery/adjust their screen brightness for indoor use.
But when the surrounding light passes some threshold (ie, outside), the auto brightness feature overrides your user settings...
thanks.....so, can i make a option for this?

No, there's no select-able option for it. It's always on.
check "brightness level" widget in android market. I just added to my desktop and it has an autolevel option. Seems to work. But I can't say if it's really off when you select only a percentage.
LOL! Check some of the newer topics. Many users want to disable the auto brightness. The topics have some info for rooted users. But as said it seems to be enabled by default.
It's not linked to the 2.3.3 update though. My desire Z also had that Android version and still provided the auto brightness option in the display menu.
It also seems to be the reason of the flickering screen on low backlight setting. That is in fact annoying.
So, how can i disable the sensor? I want my screen always to be bright, i hate this auto adjusting

See this [HOWTO] disable ambient light sensor for LCD in xperia mini. It might work on Ray too.

Thanks. I wanna keep my warranty though
If there is a light sensor on my ray then it must be disabled.
Mine does not react to any changes in light at all - even if I manually cover the whole of the top of my phone in my fist.
I also find that the screen is odd outside in the sun. It looks exactly the same if it's set to 25% brightness or 100% brightness (both are just as easy to see). I can only notice a difference in brightness when i'm indoors or if it's dull and cloudy.
FYI i'm on 4.0.A.2.368 - 2.3.3

Screen Auto Brightness is not working on my Xperia Ray too.. I don't know why this feature was disabled... I tested light sensor and that works but brightness never changes... Is it because of old 2.3.3 firmware i have ? I didn't update to latest yet..
I don't know if it's just me but sometimes my screen kind of flickering.
Is it true that it's because of the light sensor just too sensitive?

For me,Xperia Ray owner are very lucky.
Because the light sensor is implemented very bad on Xperia Mini for example.
The screen flickering and your eyes cry. : (

Yes,is a very boring problem.
The Xperia Mini has two big problem.
-Touchscreen lag
-Flickering screen
Check out this post on the Xperia Arc - works great just the same for the Xperia Ray. Also the linked program well depicts the relation ambient light value, brightness setting and the resulting screen brightness.

[Q] Light Sensor..

Usually, the light sensor is used for adapting the screen/display light/brightness in relation to the environment light/brightness.
At least when you have enabled auto-brightness in menu "Settings" > "Display" > "Auto-Brightness".
So, the screen brightness will be reduced in the darkness to safe battery power.
If you have disabled the light sensor, you should also disable auto-brightness and set a fixed birghtness level.
Good luck !

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? ?

Oneplus X Sultancm13 Enable Ambient Display but Disable Screen Pulse Notification?

Hello all,
I was just wondering if there is a way to enable the beautiful ambient display since the 1+x 's proximity sensor is really responsive, but I dont like the screen pulsing for battery life and "pocket dial" reasons.
I would still like the proximity sensors to work when i wave my hand or take out of my pocket, but it would be great if i could disable the screen pulsing somehow..
Thanks
Should be under doze in settings.

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.
