they are on by default over here..i haven't used android long enough to change the setting if it even has one so mine has to be default. I have my brightness set to auto but im pretty sure that was default also.

me neither :/

Mine also automatically lights up when I hit the power button. I have not done the OTA.

That's SO weird. After reading the title of this thread, a few seconds later, my lights stopped coming on, too.

Turned it off, pulled the battery, and now it works fine.

ya mine just randomly started working with no reboot ahah..how weird..now to get my ota >/ still havent got it yet

I just came in here to find this thread (how do you search in the XDA app??) because I am using my phone in the dark for the first time (hotel, trying not to wake my girlfriend) and my buttons weren't lighting up.
I did a quick Google search and found they won't light up if you turn the screen on when the phone is plugged in, and this is apparently by design.

For some reason mine never work in the morning in the dark (when I actually need them to), but they always work during the day. I figure there is just some bug with the light detector.

For those having issues with the lights not turning on, are you plugged into a USB cable? Mine do not turn in when a USB cable is plugged in, but they do otherwise.

Mine never turn on at all. They haven't since I got the phone. At first I thought it was by design then I realized how stupid that would be and looked it up. Sure enough here is the thread with people having the same problem...I'm on hold with HTC as we speak...

Capacitive Touch Buttons won't Illuminate
I found this thread in a Google Search and wanted to bump it:
I just picked up my white EVO today. I just noticed my capacitive touch buttons don't light up, though they do function. This makes the phone impossible to use in the dark. I was going to ask if this was a setting I was missing, but after reading this thread it seems like a small bug. Have anyone found out what the status is on a fix? thanks!

Ok guys I discovered that the button lights have a light sensor, this sensor is located under the earpiece speaker on the left side looking at the phone. If you have it plugged in you can cover the sensor up with your thumb and the lights will turn on. The lights also will not come if you are outside or in a well lit room. I hope this helps, and still dont know what to tell the OP as his happened in the dark.

Beware of the Brightness Of Death

Hi all,
On a number of occasions, I've used Market apps to control the screen brightness, either manually (like a brightness widget) or scheduled (using Timeriffic - a great tool for automatic profile changes throughout the day).
Apparently, these apps are not aware of the correct minimum brightness supported by the Leo, making it too easy to go too low, which essentially disables the display completely.
Touch still works, so if I'm lucky enough to remember the location of the widget/slider/controls, I may be able to turn brightness back up to a "sane" level.
For example, Timeriffic turns the screen off with a brightness level of 10% - 15% is the lowest working setting.
If I'm unable to fix it this way, I'm basically forced to reset. The problem is that Android *remembers* this setting after a reboot, and reapplies it just when the device is vibrated slightly at the "Android" logo animation. Thus, with a black screen, it is impossible for me to unlock the SIM, hard to unlock the screen lock, and virtually impossible to correct the brightness setting. I need to remove my data.img ("hard resetting" Android) and restore what I can from backups.
The problem also seems to occur with the standard screen dimming which occurs at about half time before the "screen off" setting. I can see the display start to dim, then it suddeny turns off. In this case, however, Android of course reverts to normal brightness at the touch of the screen or press of a button.
On a related note, I have experienced (like right now) that brightness range used by Android is much dimmer then normal. That is, using the regular brightness slider in Settings, I can only vary between almost invisible (min) and quite dim (max). Curiously, in this situation, the display can get *much* dimmer than normal, without becoming disabled.
Any ideas on these issues would be most welcome!
Workarounds found later in this thread:
- Shine a bright light on the screen - the graphics are still there if you look really hard. It's not a joke!
- Use Screencast in Droid Explorer to "remote control" your Android
- adb shell "echo 255 >/sys/class/leds/lcd-backlight/brightness"

I don't know these app(s) but if they are writing their settings and configured values into a ini or settings file, than you might be able to connect via adb and change the setting by this way.
With tools like Droidexplorer or ADB magic, browsing through the files should be very comfortable and you might find the correct file.

this happens on regular android devices ...i have a couple of them

What happens? That brightness is set too low, essentially disabling the screen, so you're forced to hard reset or perform some root magic? How do you cope with it? Or does it happen that the permitted brightness range is just dimmer than usual?

Btw, until there is no light-sensor support in kernel, you can't use such apps for the brightness

Stills a good advice

I have had the same issue with the brightness range being too low. The max brightness is really dim and the colors don't seem right. That may just be the dimming effect though. If I restart the phone it seems to take care of this. I have not had the screen go below the minimum level and turn off though.

is there a fix for this. i just experienced this problem

I experienced the same with Multicon widgets.. had to delete Android and start over

Oh wow, not good at all, crap...
so that means if i do that i'll lose everything huh?
Theres no way to restore the factory brightness or factory settings for the android?

As long as you have a working WinMo it should be possible to edit the values of brightness, but I have no idea where this information is stored.
Deleting Android folder and unzipping again is esentially restoring to factory settings.

yea this happens to me all the time, its a *****. it cuts off at exactly 12% for me. what i do is have aldiko(a book reader) on the home screen. if i click on it and open a book i can just swipe on the left side of the screen to adjust brightness. since i know that its on the home screeen on the right side middle, i can usually find my way back to it.

which means that i'll lose everything such as data correct? new contacts etc. msgs...

any thing on this... isnt their a file in the android folder that i could maybe replace to restore to factory settings.
and could someone post a screen shot of their phone so i know where the numbers for the pin code lockscreen. tryin to get past that, then i can adjust my brightness

LOL I experienced it one time. And I must delete data.img to restore the phone. After this, I don't use any brightness tools (except ones already in the Android build).
If anyone have solution, please point us

Well i was able to get my screen back to normal. lol.
I didnt delete the data.img, i simply copied it and then removed it, started a fresh install, and then just marked on my screen where the numbers were, turned it off, put the old data.img back. Followed my marks, and was able to unlock it and then found the power control widget. And bam! screen back to bright...

This might work for you!
Erm... In similar circumstances I found this worked...
I was trying out different Android builds and I found a screen brightness widget. It had various available levels of brightness, one being 0%. As soon as I selected it I felt pretty stupid as true to it's word it gave me 0% brightness placing me in a similar position to the OP.
My Solution. I used my (very bright) led torch to light the screen. By playing around with the angle and beam width I found I could just make out the on screen graphics enough to re-adjust the brightness level.
Simples!

Just as " Justblair " said .. you can place your device under a very bright light thus you'll be able to see the screen and what it's showing .. idk what build you guys are using but in cyanogen you can adjust the lowest dim level so that any app or widget tries to set the brightness to 0% it's automatically set to your preset, 15% for instance.
I've only faced this problem once

Is it absolutely necessary to flood the main thread with all these useless noob posts?
It really has nothing to do with Android development on HD2 and should be posted in the General section IMO.

Cyanogen allows you a max dim level of 26 - which is too little on the HD2.
In Tasker, 30 is the lowest setting that still provides light. Maybe Cyanogen can be patched for the HD2 in coming builds?
Thanks for the tip on shining a bright light on the screen.
Another tip is to use Droid Explorer's "Screencast" feature, to view and control your Android's screen on your PC desktop. Of course, the brightness setting has no effect here.

Some Brightness change in my display

I find that my device have some brightness change in the display,many times i'm reading and see the screen do some dimming the screen lower down the brightness and go back after like 30 seconds to the normal bright,I have enable the Auto screen power but i try desable and the result are the same.some help please

Probably nothing you can do and it will just never work properly. Seems like the Note has the same strange auto brightness behaviour as the Nexus One - it doesnt work right. Must be some problem with Android OS? I just had to accept the crappy touch screen problems with the N1 and you'll have to just accept that your brightness is screwed up.
Why even include these features if it doesnt work right? Or why not just be honest and tell consumers that the feature has glitches? Why not steal some programming from Apple - never had an issue with iPhone auto brightness.
I still will probably get this phone - but I think it's ridiculous that a $700+ device has these auto brightness/screen issues reported here.

[Q] Auto dimming my car mounted Nexus 7

So I've been doing some general googling, and I haven't come across a good solution for my issue, so I thought I would post it here. Nexus 7 is mounted on the dash of my car. Powers on and powers off (deep sleep), connects to hotspot fine, generally, is working great. HOWEVER, there is one feature that I would love to be able to replicate from OEM in dash systems that I've seen. I would like the screen to dim when the unit isn't actively being used. Not time out and go to sleep, just dim (or maybe even turn off the LED backlight). Then, when I tap the screen, I want the screen to come back to automatic brightness mode based on the ambient light sensor. I've found plenty of apps that will turn the screen on or off with various gestures and such, but they all seem to require disabling or otherwise changing the way the ambient light sensor works. From those of you that use these in your car, I'm hoping that you have some suggestions. Thanks in advance.

Hi, bigdogbts...
What you suggest certainly sounds feasible. I have no immediate solution, just some ideas/pointers.
Three pieces of software come to mind...
A Custom Launcher such as Apex or Nova. These give you a double tap gesture on the screen, which you can associate with some action to run... app, shortcut or 'activity'.
Lux Auto Brightness.
https://play.google.com/store/apps/details?id=com.vito.lux
This is capable of reducing the screen brightness right down to zero, such that the device looks likes it's turned off.
Tasker.
https://play.google.com/store/apps/details?id=net.dinglisch.android.taskerm
An app which is capable of automating all sorts of things on an Android device. You can associate an action instigated by the the user with a desired objective. Unfortunately, it has a bit of a steep learning curve... I bought it myself a few months ago, and I still haven't got around to really fully understanding it.
I suspect that if you can 'associate' Lux Auto Brightness (set with some pre-arranged brightness settings, ie., a completely dark screen) with a specified action (like double tapping the screen) with either Apex or Nova launchers (via gesture) or possibly with Tasker, maybe via a script...then you may be able to accomplish your goal.
As I've said, I think that what you're asking sounds possible... it's just a case of finding the right apps, and 'stitching' them all together. And maybe with a bit of tinkering with the apps I've mentioned, you can, hopefully, get something that works,
Good luck.
Rgrds,
Ged.

I think tasker can do something like that.

Screen auto turns off. Quadcore R16 1.6G

I have an unidentified Head unit (this one http://www.preston-i-c-e.co.uk/vw-006-oem.php) and I've obviously changed something with buttons and now the screen turns itself off after a few seconds.
Brightness is set on auto, and to keep awake. Sat Nav stays lit all time, but any other app turns screen off.
Attached is system details. I'd love to know more about it!

contact the guys you bought it from?
i think there's a setting for screen auto off time, but you have to look for it. my unit(s) don't have this.
try display settings, under brightness, or factory settings somewhere...
