Is this the case on anyone else's phone? Mine only light up when I am in a dim room. I can force them on my covering the brightness sensor. My Inspire would light up whenever I hit a button. Is there maybe a setting I am missing to turn the feature on?
Mine don't light up either. I noticed it last night when I was using the phone in a low-light, but not totally dark, situation.

This is the new way that HTC is doing things now - on their newer ROMs, the hardware buttons are programmed to only light up in a dim room, to save battery. The theory is that in a bright room, you will be able to see the buttons anyway, therefore a backlight is unnecessary and just wastes battery life.
edit: I accidentally hit your thanks button, so have a free "thanks" on me.
Not exactly "New" persay considering other Devices are starting to do this as well. For instance the New Atrix 2 they did the same thing unless it is dark the buttons will Not light up until you press on them. So it seems to be an ongoing new thing with most likely all manufacturers to try and save battery life without throwing in a Larger Battery.
In Sense ROMs, the amount of ambient light that triggers the backlight can be modified, although it takes a little knowledge of ADB and messing with APK files. You can decompile framework-res.apk and edit the arrays.xml file (config_autoBrightnessButtonBacklightValues) to make the buttons come on at higher ambient light levels, then recompile the apk and push it back to your phone.
The stock ROM is probably configured something like below, which turns on the backlight only at the lowest ambient light level:
<integer-array name="config_autoBrightnessButtonBacklightValues">
<item>255</item>
<item>-1</item>
<item>0</item>
<item>0</item>
<item>0</item>
<item>0</item>
<item>0</item>
<item>0</item>
<item>0</item>
<item>0</item>
You can edit the entries to something like this, if you want your backlight to stay on at a few more higher ambient light levels:
<integer-array name="config_autoBrightnessButtonBacklightValues">
<item>255</item>
<item>255</item>
<item>255</item>
<item>255</item>
<item>-1</item>
<item>0</item>
<item>0</item>
<item>0</item>
<item>0</item>
<item>0</item>
If CyanogenMod ends up being ported to this phone, you can do the same thing in a much easier way (in CyanogenMod settings, in the advanced autobrightness tweaks).

"per se" you mean.
I've already experienced this with my phone, but I know it's normal. In brighter environments, the keys don't light up at all. They do when I cover the light sensor or enter a dark room.
I prefer this way more than having them on all the time, it is a waste of battery. I mean there is no need to light up the buttons unless you are in a dim light enviornment

Hey guys, I know that the Kaiser has a light sensor to tell the keyboard when to light up (at least I think I read that somewhere)... So does anyone know a program that uses this light sensor to adjust the backlight of the screen according to how bright it is outside? I would love it so that when I'm indoors the backlight is dimmer to save battery, but when outside in direct sunlight it gets brighter so I can see it well. Anyone know if this is plausible?
If a program doesn't exist, I'd really like to develop one. However, considering I have no experience, I would need considerable help. If someone is interested in developing this, that would be awesome!

I don't think there are any light sensors on the Kaiser.The keyboard just lights up anytime when you want it, I think there is a setting for that.
to the left of the letter q on the qwerty keyboard there is a sensor that makes the keyboard light up when it is dark
If you press a key and it is dark, the keyboard backlight will invoke, and if its light out and you press the keyboard, the backlight does not invoke.
what dyou mean lights out
the backlight will light up whenever the sensor next to the q senses no light

He said when it's light out, as in when there is a lit environment.
Anyone have any ideas how to tap into that sensor? Or perhaps have the lens of the camera sense light when the keyboard is closed somehow for the backlight? Am I thinking way to hard about this? lol
keyboard light sensor
Turning off light sensor for keyboard:
Start/settings/buttons/backlight tab/uncheck "enable keyboard backlight auto sensor". That's it.

Keyboard Backlight Time-Out
My backlight comes on fine, but no matter how dark it is, it will not stay on for more than a few seconds. So then I have to hit just ANY old key to try and start typing again.
Anyone know how to make the KEYBOARD backlight stay on longer?
Thanks.
i have a problem with light sensor. sipmply is not working.. when i turn it on the screen goes to lowest settings.
I installed the "water level" program an i see that there is always at 926 lumens. any idea whats wrong?
i try hard reset but the problem persists.
What I did for it to actually start working was I put the "On battery power" all the way to power save, and then selected "auto adjust backlight.
I might look stupid here, but my screen goes dimmer in a pitch black room, and brighter when there is a lot of light. Is this how it works?

That's right - if the environment is darker you don't need that much backlight for the screen to be readable. The more light is shining at the display the brighter it has to be in order for you to see anything. It's really more of a power saving feature...
for the record:
i return my device as DOA and now i got a new one that is working fine .
I have been noticing that my auto brightness doesn't work like it did when I first got my phone a few months ago.
Back then it seemed like it changed brightness after a few seconds when it should.
Nowadays it doesn't seem to do that anymore.
Now if I hold my phone close to a bright light, hit the power button and unlock the phone, the screen is very bright, as it should. When I hold my phone in a dark place, it doesn't adjust the brightness. It keeps being very bright.
BUT, if I hold my phone in a dark place and hit the power button and unlock the phone, it's dark, but when I move my phone to a brighter location it does make the screen brighter.
I first thought this had to do with CM, but now on stock froyo it does the same thing.
Is this normal, and am I just mistaken? And should the phone adjust the brightness when I hold my thumb on the sensor thats just right under the power button on the front of the phone (I expect the screen to be less bright)? Because it doesn't do that.
Thanks in advance.
No it's not normal, mine reacts to changes in ambient light in a second or 2 (FRF50), just like yours used to.
When I cover the light sensor with my thumb, the screen dims right down.
Thanks for your reply.
Is there anything I can do to check why this doesn't happen on my phone?
Can I perform a check on the status of my sensor, on it's behavior?
And are there any known reasons why this could happen?
Thanks in advance.
This exact issue is happening with me ever since I updated to 2.2. It worked perfectly before but now I notice that once the screen adjusts to maximum brightness in a well lit area, it never dims....don't know what the problem is. But I hope there is a solution.
Good to hear I'm not the only one with problem, that gives me hope this might be a software issue rather than a non-working sensor.

Actually I may have to take this back, in retrospect, the dimming actually could have been the screen timing out.
When covering the sensor with my thumb and not having the screen set to 15secs, it doesn't dim until I lock/unlock the screen.
Reading on another forum this is by design rather than a flaw, as people complained the screen would fade in and out in certain light conditions... now it can't.
Ah, okay. Good to hear.
Thanks again, Rusty.
froyo seems to fix the autobrightness for me, at least now i can see the screen brightness is changing according to lighting condition, previously i don't notice it (using cyan ROM prior to froyo).
Even in a dark room the backlights for home and back do not light up. The only way to light them is to cover the top of the phone. Any suggestions? Thanks
I found my answer to this. The light sensor is too sensitive...it does not work as it should. The sensor is the top left corner circle on the front of the phone. I just put a piece of black tape over it. Now the backlight buttons stay lit and I can see them in a dimly lit room.
ha. :silly:
I didn't even know they had lights?
Learn something everyday.:good:
I really don't want top have to put tape on my pretty new phone. But I'm glad to find out that I can cover the light sensor and then the buttons will show up. Hopefully that will get fixed with an update
I'm using an app: capacitive buttons backlight (i think it's called)
Edit: Capacitive Buttons Brightness
Sent from an HTC One with using xda app:
TrickDroid ROM 5.2.1
teaMSeven(stable) kernel 3.7
I quite feel that the ambient light sensor/whatever you call it is not very intelligent for following issues:
1. Auto Screen Brightness: Screen remains too bright even in dark environments. Also, the screen flickers when adjusting its brightness
2. Soft buttons light: This is a widely known issue...Home and Back buttons dont light up even if its verryyyy dark! I sometimes put my finger on proximity sensor to manually trigger the lights! :silly:
3. Auto Flash in Camera: This is something I have not seen anyone commenting about. Yes, I agree that professional photographers avoid using flash as much as possible, but i feel the HTC One uses flash (when set to Auto) only when its pitch dark! In dark areas when One wouldn't use turn ON flash, the quality of pics was a million times better when I force enabled the flash!
All these are minor quirks but we face it every time we use the device, and hence are pretty annoying.
Is anyone else facing these issues?
Btw, I'm running the latest 29 firmware..

There might be something wrong with your light sensor, where it's detecting higher light levels than it should be. It shouldn't have to be really dark for your soft buttons to light up. On a scale of 1 to 10, where 1 is a very dark room and 10 is a sunny day outside, your soft buttons should be lighting up at 3-4 or lower. If you're interested, here is the actual algorithm in the software code (arrays.xml inside of framework-res.apk) :
<integer-array name="config_autoBrightnessLevels">
<item>11</item>
<item>41</item>
<item>91</item>
<item>161</item>
<item>226</item>
<item>321</item>
<item>641</item>
<item>1281</item>
<item>2601</item>
</integer-array>
<integer-array name="config_autoBrightnessButtonBacklightValues">
<item>255</item>
<item>255</item>
<item>255</item>
<item>255</item>
<item>-1</item>
<item>0</item>
<item>0</item>
<item>0</item>
<item>0</item>
<item>0</item>
</integer-array>
The first set of numbers above is the lux value (the ambient light level detected by the phone's sensor). The second set of numbers is the corresponding value assigned to the button lighting (255=on, 0=off). Using the above settings, when the lux value is 160 or lower, the buttons light up. A lux of 160 is roughly a medium-low lit room indoors. For example, in a somewhat dim room at night with a lamp in the far corner, your buttons should be lit up.
If your phone's sensor is incorrectly sensing that the surrounding environment is too bright, this will also cause your screen to be brighter than it should be (along with the buttons not being lit up). However I do agree with you that the default values for screen brightness are too high. I think HTC wants to impress us with a bright vibrant screen when we're looking at it in the store sitting next to a Galaxy S4. The default brightness values are:
<integer-array name="config_autoBrightnessLcdBacklightValues">
<item>39</item>
<item>56</item>
<item>56</item>
<item>90</item>
<item>125</item>
<item>142</item>
<item>170</item>
<item>199</item>
<item>227</item>
<item>255</item>
</integer-array>
Personally I set them to this:
<integer-array name="config_autoBrightnessLcdBacklightValues">
<item>39</item>
<item>39</item>
<item>45</item>
<item>80</item>
<item>100</item>
<item>100</item>
<item>150</item>
<item>150</item>
<item>227</item>
<item>255</item>
</integer-array>
This lowers the overall brightness in normal situations while still bringing the phone up to full brightness when outdoors. It also lowers the amount of up/down frequent brightness adjusting the phone does in situations where the lux value is fluctuating frequently on the edge between 2 adjacent values.
EDIT: Thanks for the info.
Hi, i have an HTC ONE with GPE 4.3 and TeamSeven kernel.
I see that my button backlights only come on at 160lux..
However i have extracted the frameword-res.apk from my rom and cannot find the array.xml file.
The rom is bigxie_m7_GPe_JWR66V_odexed.
I'm fairly new to root and playing with android but more than capable to edit and find my way around with basic instructions if anyone can help?
Thanks
