Hi members.
The live with walkway has got a light sensor. Why has Sony disabled automatic use of this sensor. I can't find an option to enable it.

Well as far as I know the brightness adjustment it's always there and there's no way to turn it off.
Weird I know because you can change the light intensity under the screen options and the sensor it's not able or at least not in any of the roms I tried with this option to completely and automatically adjust the brightness.
You can complain to sony it is they doing.

When it is always there and active, then it isn't function.
In service menu I can test the light sensor. The values change when I put my finger over it.
But in normal phone use the brightness doesn't change. When I put my finger over the sensor then it should reduce the brightness.

Brightness does change, but the difference is quite small.
Sometimes, you might see screen light a bit vibrating/flashing, that is because of the light sensor.

I hated that brightness sensor. At first i tought the screen was about to expire. Used this app (i think it needs root) to dissable the auto brightness

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

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?

Because the light sensor is implemented very bad on Xperia Mini for example.

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.
Guys as you know, Xperia neo's brightness (maximum) is very low compared to ARc or even X10 mini pro. My mini pro at 50% is equal to the 100% brightness of my Neo. Is there any trick or hack or whatever it is to increase the brightness above 100%? Something to override the maximum brightness? The screen is annoying under the factory set max brightness as the white colored pages look yellowish.
Is there some way to increase the brightness beyond the factory settings?

SuperDIM only lets the brightness go below the minimum, not higher than the maximum on stock.
I agree with genothampi ,the brightness in NEO V is very low compared to my X10 , there should be a way to increase the brightness higher than the maximum on stock or maybe the devs find a solution for that .
happy new year to every one
The MIUI ROM apparently does increase the brightness upto a crazy amount xD
Try it :
Should be ported to Stock
you use the light sensor of the phone? on my xperia neo I have disabled the sensor light (root+Disable Auto Brightness PLAY) and now the screen is beautiful, too bright. the Brightness options (in display) I have put in 60%, and still bright
sorry for the english

first I have modified the file hw_config.sh using root explorer, but I don't liked, because when I turn on the phone in a dark place the screen was dark, then I had to turn on the phone always in a bright place
now I use a app, Disable Auto Brightness (PLAY) and works perfect now, when I turn on my xperia neo the app disable the sensor light and the screen stay maximum brightness
anything, just ask.

I have already fixed the brightness on my rooted Neo V using the app ( disable auto brightness ) but my question to you is , would you port the hw_config.sh from the s.e tweaked Rom since you are saying that the light sensor disabled by default , so this way we can apply that to the ROM and no need to install the ( disable auto brightness ) .
thanks in advance

or you can try disable sensor for free with method used in this thread http://forum.xda-developers.com/showthread.php?t=1426948
I have bought Hatcyl's app but I like more this free method, because it has lower minumum brightness which is important if you want good battery life.
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.
Sent from my U8800 using Tapatalk 2
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.
Hi All,
Could you please point me on the file that has settings for auto brightness? I want to increase the range, the stock one is almost unnoticeable.
Thanks in advance!

But without custom rom or app you cannot control it.
Cyanogen mod or app ( widgetsoid) can control it very easy.

It has auto brightness. You can go to the Service menu, Sensors section and there you will find Light sensor, there you will see its current values, as far as I remember they are 0..12 or so, but that doesn't really matter, I want to find where the dependency between Light sensor value and brightness is coded.
You should ask some rom dveloper for some info :-/

I found this useful post.
In ICS we have it in /system/etc/als_curve and there we have 4 folders: 0, 1, 2 and 3 with limits and parameters. I assume these are 4 zones of brightness (0-25% on folder 3, 25-50% in 2, 50-75% in 1 and 75-100% in 0).
We have to change the parameters, as in the post I referred, but personally I didnt understand almost anything, so we need to try... If someone will be trying too, let me know your results!
I have found an easy way to set auto brightness and it works beautifully:
Download and install quick settings.
When you are in quick settings, tap "customize", tap the small tool icon next to brightness, and you will be asked whether to enable light sensor.
Once enabled, you will be able to use auto brightness through quick settings app.

It is enabled by default even without 3rd-party apps. The reason of all this is to make its range bigger, more noticeable.

I also really don't understand why Sony cannot put this option just in the brightness settings.... I have had a long time thought that the SXS doesn't have auto brightness at all but dunno that its in fact hidden somewhere which can be called out easily by a 3rd party app !

It does have auto brightness, it just works a little different from what we're used to so far. You can find the brightness control in Settings->Display->Brightness (at least that's where you find it in Gingerbread). Now, the thing that creates so much confusion, is that this control shouldn't be called Brightness, but Visibility. What the phone does (and imo this is really clever), is that you move the slider to adjust the visibility of the screen best suited for your eyes and then the phone will automatically adjust the amount of light the LEDs glow using an intrinsic curve so that the same visibility is provided outdoors and indoors. You can test this. Set the slider halfway and then go outside, in the sun, and cover and uncover the light sensor a few times. You will see that the screen is dimmed and brightened up while you do that as the phone tries to maintain it's visibility to the setpoint you chose by moving the slider. Simple and clever, huh? What some may argue, is that the brightness variation is not aggressive enough, and they may have a point. Personally, I don't need to move the slider more than 20%, as the screen is perfectly visible even on a sunny day (of course, that is unless the sun directly reflects in the screen, but I found this happens only if you hold your phone on purpose and it is not a comfortable position).
Hello,
In my lt26w there is no Visibility submenu. But it looks like the application "quick settings" has make a trick.

I really liked Ambient Display on Oxygen. Just swiping above the proximity sensor would light the screen up. On CM12.1 ambient display barely works at all. Is it possible to install an apk or flash a zip to get ambient display working like on oxygen?
