Hey all,
I just got my new HTC HD2.
It don't adjust the backlight automatic even when the option is enabled.
Today was a good test because it was very sunny. But nothing happens.
I did a small test with light a few sec. ago but nothing.
The other sensor is working fine. (G-Sensor and Proximity sensor)
Any tips?
Greetings,
Henk
under the sound and display part of the settings, is the automatic brightness settings box checked?
If you find it turned off most likely your percentage will be set at 30% which means that you my friend most likely gots stuck with USED phone that was sold to you as a brand new phone...

Hello,
I have bought myself a diamond touch 2, and i directly flashed it to Dutty's R6 rom because i like it much better and i made up my mind about it even before i bought it.
Now i seem to have a problem, and i don't know what would be the problem; either the device or the rom?
Proximity doesn't work; setting automatic backlight dimms the screen to a low-light level. Holding a flashlight above it doesn't make any difference.
Also, when making a call, the display keeps being illuminated the whole time, no matter if i hold it to my ear or not.
Does someone recognize this problem?

Settings\System\Power\Backlight\ Turn off Auto adjust.
If i turn off auto adjust i can indeed set full brightness, but that's not the point. I want the auto-dimming and proximity sensor to work, so when i hold the piece next to my ear it locks and turns off the screen...
If I turn on auto-adjust, it doesn't respond on any lightchange or action; it just dimms the screen to about 40% and keeps it there.. either a bug or a hardware fault with my unit?
Not sure that it ever worked perfect out of the box.
Have you tried tweaking the settings with TD2 Tools?
How do you mean tools? As far as i know i can only find one box to turn auto adjust on.. you have the same configuration, does it work for you?
EDIT: I installed the app "LumosWizard". Now the phone's backlight adjusts depending on the light the sensor receives. The sensor works well as the values go up when putting a flashlight on it.
However, i wonder why this doesn't work with just auto-adjust on, that's what the HTC Auto-Backlight should do right? Also, with this app, the backlight doesn't go out when no light is reveived (auto-lock when putting into pants, or turned off backlight when calling...) ?
This is what i'm looking for: http://www.youtube.com/watch?v=6xakUmz1zwc
=> i don't think this is achieved by an additional application, but is just standard HTC service doing this because of putting on the auto-adjust...
There is NO proximity sensor on Touch DIAMOND II. Only light sensor. Use Touch_InCall_Screen_Tweak instead. This program use G-sensor and block the screen when your phone is in vertical position.

Thanks, installed and works good!
Still wondering though why i need a 3rd app like LumosWizard to make the lightsensor work, as htc's autoadjust apparently doesn't
I did find this .cab called Glight and it works great on my TD2

I recently aquired this phone, brand new too! Bought unbranded of course, and fully unlocked etc etc..
Problem is, when i sit in my couch at night, with my light turned on, bout 50-80cm away, that light is bright enough to fool the sensor to think im outside in full sunlight or something, cuz the "white light" in the home, menu, back, search button lights up for 1 second about, then shuts off, and dont come back on, unless i turn off the light, or hold my fingers above the top part of the screen, then it turns on, and stays on, untill i remove my hand or turn on the light, and then it shuts off after 1-2 seconds again...
Is there a way to either disable this ambient light sensor, or change its sensitivity to light... Cuz this is crazy!
Is it supposed to do that ? I think it's broken.
I have no such problem with my phone.

Go to Menu -> Settings -> Display -> Brightness -> uncheck the automatic brightness! this should fix your problem!
I dont think its actually broken though... I just realised that my HTC Desire is acting the same after the latest update, well, maybe the wildfire is just a tad more sensitive.. But if i fx just have one of the lamps on, then it activates after 1 second... :| Stupid sensitivity!!

Already done! The phone switched brightness settings too damn often for me to be sane! So that setting got torn off about 1 min after the phone was done updateing to latest kernl.
Just as the title says-
I am not able to locate the light ambient sensor on my A500 tab- My previous A500 got replaced by acer because the speakers were defective in some way-
I have read that the light sensor is located below the volume rocker and rotation switch on the black glass and can be seen under bright light- i tried every way to find it no success.
I tried "proximityscreenoff" and "sensorlist" from the market. Both of the freewares listed an ambient light sensor on my device as -"Lite-on al3000a Ambient Light sensor"-
BOTH THE APPS COULD NOT GET ANY DATA FROM THE SENSORS :O-
DO we even have a sensor? or is it just me without it?
Can someone please use the apps and tell me if any data is being collected from the sensors?
Highly appreciated- thanks you
I tried with Sensor List and it does indeed show up the sensor, but doesn't seem to be getting any data from it. So it's not just your tablet.
Same thing with "AndroSensor", it shows it but no data change in it either. Hopefully we can figure out what the issues is? Are both of you using the factory install rom? Or a rooted one with a tweaked kernel?

I got Sensorlist and tried it and I do get data from it.
xhz/xxxx or xxxxxms and a red line. The upper limit is 227 and lower limit is -227 and the red checked number changes. It's nowhere as quickscrolling as the other sensors but I get a jagged red line moving across.
okay guyz i think i figured this whole thing out most probably-
I just came back from this electronic store, i closely examined the iconia on display- a500 - noticed the black glass under the volume rocker and rotation lock and THE LIGHT SENSOR WAS THERE! :O - looking like just any ordinary light sensor-
This made me come up to the following conclusions- since i have had another iconia before i returned it for warranty- i was able to identify the following differences-
1st variant-model
Light sensor present
Mic volume low
Volume locker button hard to push
Power button sorta pushed inside
2nd variant model -( the one i currently have)
Light sensor absent? Or hidden under black glass? (Manufacturing defect?)
Loose rotation lock (hardware) toggle
Mic volume high (as in proper)
-(i faced these additional problems)-> glass over the camera came off and the glossy label on the side slipped out.
So if u have the first variant, the one i previously had and the one i examined in the shop today- that should give u data from the light sensor, and the 2nd variant with hidden/absent light sensor won`t.
These are my findings. Feel free to point out and discuss-
What should we do? I m considering a second replacement now -_____-
With AndroSensor app open, try to put some direct light above the sensor and see if it shows some readings. I noticed that the sensor is in a sort of sleep status until it sees some light; after then it kinda wakes up and works properly.
I appear to have what you call the second variant model. I just checked with Androsensor, and the light sensor does appear to be present beneath the black glass, just under the volume up rocker. I agree it does appear to sleep until it senses a light source.

I just downloaded andro sensor-
Under light sensor it sed-waiting for event-
I took my hd2, turned on the flash! Pointed it right above the sensor and no response, it just kept saying waiting for event- so does this mean i have a defective sensor?
Can this be a kernel/rom related issue?
Pls someone try this and let us all noe.
Thanks
It's a long shot but you might attempt flipping the check mark a few times under the brightness setting and "auto adjust" as that probably toggles the sensor as well, though these apps are supposed to do it. Or close and start the app a few times and then check the sensor. I don't know what activates it but I can confirm that it has some kind of threshold where it sleeps or isn't active and another where it is, so you might want to try various things to, as others have mentioned, wake it up.
Are you using any ROMS by any chance or are you on stock? Have you done any sort of modification of the system - rooted and removed things or replaced kernels, etc?
If you are on a ROM or have done any modifications, you may want to try going back to full stock 3.2 or 3.1 and seeing if that helps before you decide it's actually defective.
Just double checked mine running a 3.2 rooted with thor's kernel. The sensor is working fine. But i did have to uncheck the box for the auto screen brightness to wake it up. Then i used a led maglight on the senor.
Readings from Androsensor:
Light (0.5mA)
55.0 lux
With the maglight cut on it.
65790.0 lux.
Please note with the maglight cut on you can see the light sensor hole then.

Same as Killer, seems to be working, rooted 3.2, couldnt see until bright light on it.
Anyone have any idea where the mic(s) are, not really important just wanna know which end to scream into when doing voice search
Mic is located directly in the top center of the front face, in the space between the glass and the bezel. You should be able to see it with just a small amount of light shining on it.
FINALLY!
after various non stop auto brightness toggle on and offs - waiting for event went and 1 lux came xD - i shone light the reading increased - and stopped working agen :|
I dunnu maybe the apps are not fully compatible.
I can say it is working because i changed my brightness to full manually and then turned auto on and the brightness level set itself automatically.
So will we have to wake up the sensor from a state of sleep all the time or is it just for the apps xP - last confusion.
Thanks every1 for ur responses, the mystery is finally coming to an end xD!
Hi, My T-Mobile DVP's auto brightness doesn't work after i upgrade it to mango. It worked in pre-mango, if i cover the light sensor or light it up, the screen brightness would be changed. But it isn't like that in mango (version 7720), no matter i do, it is always at the lowest brightness level. The light sensor still works well in EM, it can detect lux value so i think this is a faulty OS firmware.
So after upgrading to mango i lost two sensors: compass and light sensor (Well, compass still worked in EM in pre-mango but in mango it doesn't work, even in EM). I lost my faith in Dell, too . My Dell laptop dead one month after end of its warranty and cannot be repaired, now this one ...
Anyone have the same problem ?
A reset fixed mine.

Hmm its not instant and it takes 5-6 seconds to adjust, because the light sensor is working fine in the EM app it means its working fine with the phone, also covering with hand doesn't work. Try putting it under a couch then put it by a windows on a sunny day.

Doesn't work for my DVP. I think this should be mango firmware's fault, so all DVP should have this problem. Could you please let us know which version your DVP is ?
Anyone who has upgraded to 8107, do you have this problem ? If the problem is fixed in 8107 i'll think about upgrading it manually
Try this: Turn off auto brightness, change the brightness from low to either medium or high, then turn auto brightness back on.
For some reason the brightness setting (that is inaccessible when autobrightness is on) functions as a limit when autobrightness is on. If it's set to low then autobrightness will never raise the brightness above low. Set it to high and try it again.

Good finding ! It worked ! But there is another problem . That is when i light up the sensor, it bring the screen brightness to the highest level, but it suck in that level even when i cover the sensor. I waited 2 minutes but it just didn't change, it was always on the highest level. Then after i locked/unlocked, it turned back to the lowest level.
So auto-brightness is not a completely unusable like compass, it's just too faulty to be able to use
Adaptive brightness totally stopped working after I upgraded to 8.1. Turning it off/on returns brightness to 16% no matter how I play with the brightness itself, whether while adaptive brightness is on or off. Covering the sensor has zero effect and it used to work pretty well.
Edit: phone is ta-1003
Little update with the incredibly useful reply from Nokia support: (/s)
Welcome to Nokia Mobile Care!
Some time the brightness screen is not working, I understand the inconvenience that you face. it is depend on the sensor and condition, on the all brand phone face this issues. do not worried. you can restart the device. make sure that if you use screen protector for sure this issues exist.
You also can take manual action if disabling enabling take you time. I hope you understand.
Also you can take 3rd apps from play store to try is that working better.

I have the same issue with the auto brightness setting: it goes to 11% and that's it. Not sure if this started after the N 8.1 update.
Where is the ambient light sensor located on the phone?
