Hello all,
I tried to look and did not see a similar question.
Yes, there is no ambient light sensor adjustment in the software, but clearly there is a sensor hardware on the front. There is the camera, there is the proximity sensor and there is the ambient sensor, just like bigger S3.
My guess is it is just not embedded in the software, because of laziness or what, I am not sure. My older phone had the same issue (Xperia Ray) there was indeed a light sensor but it wasn't effective. Yet there was many ways to recover the functionality at XDA forums.
Any way to revive it?
The front camera can be used as a light sensor. You need to install Lux Auto Brightness. Works like a charm for me. Please check this thread: http://forum.xda-developers.com/showthread.php?t=2282025

Thanks for the advice, it is a nice solution but this makes me ask how much damage to battery stamina is given? Power consumption must be way higher than ambient sensor.
Biggest problem is that THERE IS A SENSOR, so using a camera is only a ad-hoc solution while the sensor is already there
Thanks anyway,

It seems logical to me too that a camera will use more power than a light sensor. But I haven't done any measuring to get that confirmed. I don't think the difference is dramatic though. Anyway the advantage of having auto-brightness on my device outweighs the extra battery drain for me.
So there is a sensor, but as long as no one is able to make use of it I'm glad I have this as a workaround. Please let me know when you've managed to get the sensor activated. :victory:

Sounds like overkill.

It actually is very accurate and does not add any obvious battery drain (it doesn't appear on the Battery Usage screen) - you may optimize it further by triggering it with Tasker only when you unlock your phone, and otherwise disabling it when the screen turns off.

Is anyone aware of an automatic camera flash tweak for the Fuze/Touch Pro out there? I love using my it as a camera but feel it is hindered by what should be standard issue on a phone of this caliber. Any help would be greatly appreciated.
I would also be interested in this, it's interesting they didn't make it like this.
I was thinking about this today, it has a light sensor so it can tell when it needs the flash.
unfortunately when you face the phone to take a picture the light sensor is pointing at the person taking the picture and not the subject...
That's right, but still the ambient light is the same. So it will know if you are in a dark place (when you definitely need a flash) or a light sunny environment.
However there are other, more complicated possibilities of engaging the flash light by examining the light coming to the camera itself - this is the way most Sony Ericsson phones work...
Yeah, this would be a good mod.
I would really like a different camera software/engine. This camera is so slow, to me its not worth using.
I remember (but not for sure) a settings page that gave you the ability to test different sensors and what-not. the reason for my question is because when i make a call the proximity sensor doesnt work, and i wanna know is it because of the rom or anything software related, or is it the sensor itself, since i recently had repair done on the screen.
thanks.
Nobody knows? i got a 30-day warrenty, so if my proximity sensor really isnt working i need to know soon.
I've used an app previously that would display raw readouts from the various sensors in the device, including the proximity and ambient light sensors. Stand by while I try to find what app that was...
In the meantime, you can at least verify that half of the sensor is working by looking at the screen through a digital camera or other phone's camera. The proximity sensors works off of a flashing IR LED that you should be able to see through a digital imaging sensor. The sensor is located to the left and below the speaker.
Also, I believe the application I was using is called "Elixir", and is free on the Market.
Thanks man, great app. everything is working ok now.
Hey guys. I have looked around and can find no info on some of the tabs sensors. From what i understand the chipset is straight out of the galaxy s phones, which is the reason i see the existence of a proximity sensor but dont see any data from it.
Anyone have a clue whether it actually exists?
chipset and sensors are different things....even if the chipset supports a certain type of sensor doesn't mean it should be there if there is no need to be there.
galaxy tab doesn't need a proxy sensor cause you are not going to put it beside your face when calling...

Doesn't need and doesn't have are different things. Point is, if it was stated that the tab has a proximity sensor, where is it?
I'm pretty sure it has one, in the unofficial CM build Technomancer says he fakes i at 10CM
There is no proximity sensor in Galaxy Tab.
My CM7 sensors driver pretends there is one and reports 10CM distance so the Phone app behaves better.
Thanks mate, that's what you said in the last thread back in October, but why do all the sensor pingers see it? Are they checking code rather than hardware?
Also, is there a working, sensitive light meter anywhere for the tabs ambient light sensor? The couple I've tried refuse to work...
There is working light sensor in the Tab. Both my CM7 and Samsung ROMs support it just fine. It has range from 0 to 6000 Lux snapped to one of several levels in the kernel driver. You can actually read it from sys interface.
The proximity sensor in my CM7 sensors driver is just software reporting constant 10cm to the system. The sensors test apps in my CM7 (I uses Sensor Test and Plot http://www.appbrain.com/app/sensor-test-and-plot/com.golborne.android.SensorTest) just reports 10cm from my fake sensor.
I think there is some leftover code in Samsungs sensors driver that may report presence of proximity sensor.
Yep, i use it as well, but my issue is with the three avaliable states the driver seems to report.
I get 5, 22 and 75. Are there only three levels then? And no way to modify them outside the kernel?
I can get up to 6000lux using strong LED flashlight directly on the sensor.
There is another sys device that can read unprocessed data that has values not snapped to 5,22,75 etc... but Samsung's driver uses the snapped device (and so is mine).
This is very annoying... im trying to make an app that needs a proximity sensor to work as intended so the light sensor as well as the sleep mode implementation are really no substitute.
In any case, im sure it will be quite usefull for all tablet owners running 2.2 and up and using a case. I will have a closed beta for xda members by the end of the day, so people can test it over the weekend.
Would you like a shot, mancer?
I don't know what would you do but if I understand why not to use the g-sensor ... just like in samsung omnia...put backwards enable silent courtesy mode.
the proximity sensor will be useful if you use the leather case to close the screen when touches the screen , like ipad 2 and galaxy tab 10.1 V they have proximity sensors , but i noticed that the sensor exists using sensor applications they see it exists but not giving readings
Hi - there is no sensor, the sensor list showing it is just a glitch from the galaxy s motherboards. And the functionality youre describing is already available in my app Killswitch - you can get both the lite and full version from my signature...

Thanks I already bought it from market and it's great
Sent from my GT-P1000 using XDA App
Great! Im working on an update that will help improve the accuracy of the light sensor functions... been getting some flack for not updating it
Watch this space!
A few days ago I started to use the Automatic Brightness, but it doesn't worked very well...
When I am in bright area , the brightness increases, but when I leave the area or cover the brightess sensor, the bright the screen should change his intensity, but he remains the same, at high brightness. The brightness decreases and becomes what it should be according to automatic mode only after lock-unlock screen.
Anyone can help me?
I think the sensor dont have problem.
I think if you check the option "Display -> Brightness -> shade bright screens" (or somethink similar to that, i have to translate) it could make it work properly. A broken brightness sensor doesn't control anything anymore, my old DHD had one.
i think its a software problem
Same problem on my razr i
But on some razr HD, there isthe same problem. Maybe the software version....
I use "custom auto brightness" apk on market, and work great for increase AND decrease brightness.
For information, same problem with JB 4.1.2 update...
Anyone have the same problem and a real solution ?
::/
Thanks this app worked very fine!

Just use the app lux auto, my brightness sensor was working ok but it always too much bright wasting battery, after installing lux auto and understanding how it works i have to say its perfect now!
Any one know how to fix low flash brightness ???
Please I need help !!!
You mean that the camera led flash is not bright enough?

What troubleshooting steps have you taken?
How do you know it's not as bright as it should be?
When did this start happening?
How long has it been going on?
Just saying, "this doesn't work, please help" doesn't give us any information. Imgaine taking your car to the mechanic and just saying, "my car doesn't work correctly. Fix it." Then just walking off.
I have compared my note 7 and note 8 led flash light with other phones, And yes, compared to others it seems to be less bright, but, the intensity is adecuate for the camera, the light intensity is designed to work fine with the camera's parameters it is not meant to be used as an illuminating lantern for other purposes, the important thing is to check if your dark enviroment photos using flash come out as they should
