Does HD have a light sensor? - Touch HD General

Can touch HD adjust the screen brightness automatically like the blackberry curve?

I really think so, also the Diamond has the light sensor. ;-)

Automatic Light Adjustment

I've just bought a Touch 3G and as far as I can tell the Auto setting for the Backlight doesn't seem to do anything. As my last phone (P3300) didn't have this, what should I be expecting to happen? I've tried putting a finger over what I think is the sensor (right hand "LED", beside speaker) and nothing changes.
Thanks, W.
Did you set Auto adjust backlight in system menu?
Imho it is a really subtle effect. You can see it a bit when holding the light sensor (right to the speaker) to a bright light source. The display then gets a little bit brighter.
If you would like to increase the effect or customize the stepping, try g-light ( http://www.ageye.de/index.php?s=glight/about ), it lets you set specific values for each reported value from the sensor, and set the polling interval
Jade auto adjust is poor
I had the diamond prior to purchasing the jade. The diamond auto light adjust was very noticeable compared to the jade. In fact I didn't think the Jade even had a light sensor until one of the other users pointed it out.
After a little research I found this thread. http://forum.xda-developers.com/showthread.php?t=450318
I used it on my Jade and it works great. One of my problems with the diamond was the fact that the light would not automatically dim enough in low light conditions.
Thanks for the link. Now using G-Light which works pretty well. Not perfect as its sometimes a bit erratic but certainly makes better use of the light-sensor than HTC!

Keyboard illumination

Did anybody got a idea to switch the Keyboard illumination separately off.
During specially ambient light conditions the keyboard layout comes unreadable.
Thanks Ingo
on my device, the KB lights are automatically turned on if the light is not enough, it's using the light sensor (same for LCD brightness).
Same, when the light is very poor the light sensor triggers the keyboard lights to turn on
Yeh
One thing I have been very pleased with on my Xperia is the sensitivity and success rate of the automatic light sensing.
Every phone I have had in the past 5 or so years has had this sort of thing (incuding almost every N series device from Nokia and an iPhone and non even came close to switching as correctly (at the right time) and as quickly as this does.
I have not once yet found myself having a problem with seeing the screen or Keyboard.​

Proximity problem

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

[Q] Anyone able to locate just where the light sensor is?

This may be a total noob question, but I was just curious to know the exact location of the light sensor because I cant seem to figure out where it is located.

That dot that looks like a front facing camera (FFC) - that is your sensor there that controls screen on/off on calls and the auto brightness.

Are you sure, because when I ran sensor test that dot did change the proximity sensor values, but the light values wouldnt change even if I covered it completely.
The only way I was able to change the light value was to move the whole phone into a darker or brighter location, but not by finding a pinpoint sensor on the phone.
Edit 2: When I cover the proximity sensor dot (the obvious one) with my finger and shine a light at the phone, nothing happens, and when I remove my finger from the dot and shine a light right on it, the screen gets brighter. I suspect both sensors are in the same spot (the plastic dot you see probably transmits ambient light to the light sensor as well as housing the proximity sensor, in the way many computers use a little clear/frosted plastic piece to indicate the status of an LED that is buried in the chassis.
Try it with a flashlight and see if you get different results.
If you are interested in disabling the light sensor go into settings and manually set your brightness.
I have to say the proximity sensor works much better than on my Hero.

i noticed the proximity sensor responds much faster than the one on my Evo
The light sensor is just to the right of the proximity sensor under the speaker grill. Turn on auto-brightness and test it with your finger.

I guess that's why it would be working better!

[Q] Problems with ambient light sensor

Is anyone else having problems with the ambient light sensor? Mine doesn't seem to work at all. Anyone have a fix for it?
Same issue with my a500, but I think it is software related (official acer 3.1 rom)
Does anyone known where is the light sensor at all ?
It's at the top of the tablet, if you hold it with the camera on the right, it's about 2 inches from the left side. You can see it if you use a really bright flashlight, but other than that, it's pretty hard to spot.
You could use Brightness Level by CurveFish to manually set your a500 brightness and bypass the ambient light sensor.
The light sensor is on the top edge of the glass,its about 1-½inch from the left under the volume rocker. Works fairly well for me without the tab in the case a small hole is not enough light, my openion.just a bit slow
I noticed that it starts working only after pointing a flashlight (my HTC desire led flash) directly on the sensor. Use Androsensor from the market to get readings from the sensor.
