Home, Menu, Back, Search lights are not on - EVO 4G General

The lights for the Home, Menu, back arrow, and search key only come on 40% of the time. Does anyone have information on how to fix this?

I assume its a hardware problem, I wish I had the option to turn mine off.

They only turn on in low light settings. Cover the light sensor and they will come on. There was a glitch so they didn't turn on when charging, but I think it was fixed (?).

The lights are tied to the ambient light sensor. They only come on when you are in a darkened room. Also, they don't come on when the phone is charging (at leasrt mine don't).

Just download the app "LEDs OFF" from the marketplace. It's quite useful and I use it just about every night when the lights are low and I want the device as dim as possible. If you have a problem with the lights flickering, you need to download the latest version of SuperUser... This is of course assuming your on a rooted device. Anyways, just thought I would throw my 2 cents in

My lights don't come on all the time either... Pretty sure its supposed to be that way... They always come on right after un lock and go off about 15 seconds later

If you are charging the button lights generally don't come on.

Do you mean "LEDs Hack"? That's what I'm using and it works great when reading ebooks in bed.

I noticed the lights don't always come on on mine and I always wondered why this was.
Now that I think of it I suppose it's only when I'm charging, but it's quite annoying when you're used to hitting the glowing menu or back button!

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.

[Q] Ambient light sensor problem

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.

[Q] Back Light Issue - Anyone else?

I love this phone, but when I'm messing with it at night with all the lights turned off, usually the bottom softkey lights are bright as hell. I was wondering if any devs can put an option to where the bottom softkey lights only last for only a couple seconds.
Just asking, thanks in advance!
in the power options widget you can set the brightness.
you can also turn off auto-adjust in Settings->Display
fyi I've had the same problem when i turn on the phone after waking up, my eyes feel like they are on fire when the screen turns on at full brightness.
He's talking about the softkeys I think. There is an app that can change it and we at the mes forums have a mod to extend it but idk if you can shorten it.

If you're rooted and have rom manager jt has tweaks for it.

Yes but the above fix works as well. Since the DL09 update the screen timeout is linked to the softkeys. So set the screen timeout for less time. Besides optional kernals there is no other way I know of.

Setting the screen time out would affect how soon the screen AND softlights turn off, which wouldn't be any help to him because i believe what he is asking for is a way to turn off the softlights only while the screen remains on. Ever since dl09, the softlights stay on as long as the screen is on, where before with di01 and such, the softlights would only remain on for a few seconds while the screen was on and then they would go off. Im jot sure there is currently any way to turn softkey lights off while screen is on, but the mods that jt1134 has in rom manager might work.. but they were designed for di01 and dj05 and meant to actually extend the time that the softkey lights stayed on while screen was on.. as most people complained that the buttons could not be seen at night or in dark and wanted them to stay on (hence the fix for it in the official dl09 release) so there's a good chance that they won't work on dl09.

yeah, sorry guys. I meant the softkeys at the bottom. I loved how they would turn off after only a couple seconds, but I hate how it stays on for how long my screen time out is. Bothers me and I just want to go last for only a couple seconds instead of the screen timeout duration itself.

I totally agree with you, and would love to find a way to revert to the DI01 way of them only staying on a few seconds after use. Hell, I'd settle for turning them off all together so they never light up - in the daytime, you don't need them, and at night, I pretty much know where they are anyway.
I wish I could figure out how to keep mine on. I'm running dl09 and idk if I installed a kernel or theme that caused the issue but once my screen dims the lights go out and won't come back on until I physically touch them. They used to turn on once I touched the screen.

[Q] Keyboard Backlight problem

Hey.
My Droid pro is barely a month old and Im experiencing difficulty in getting the backlight of the physical keyboard to light up when its dark.
If i tilt it upwards, it comes on sometimes but this too is very random with no specific response to any particular type of lighting.
Its ALWAYS on in the day but never in the night
From what I've read, turning off automatic brightness setting is a solution but it has not worked for me - my phone has been on a custom brightness setting since day 1.
HELP!
do u have a screen protector installed?
No screen protector. that would solve the problem?
I just noticed this problem as well while I was trying to text in bed with the lights off. Couldn't see a damn thing
keyboard light problem
I have the same issue,i wished motorla would do a update and fix with a setting for that,in the meantime,I always hit the on off button and then it stays on for a bit
Not sure but...
I never had this problem until I downloaded am alternate keyboard. i installed swype and this problem started. Have not uninstalled to see if it fixes the problem
If your rooted then try installing keyboard backlight from the market. It works great for me.
Ive never had a problem with my backlight. Night or day.
backlight
I too have the same problem,im like the others,wished motorola would fix this and make it adjustable, i have a semi fix til they do fix for good,when u notice it is not on,reach up and just push the power button for the screen to temporarily shut off,then push power button again,use slider to open screen and then it should be lit up then,thanks
Any try the backlight app and see if that works?
which app is it? a link would be nice
if you have a screen protector, use a hole punch to cut a hole in it above the light sensors.
turn off automatic brightness.
with the backlight on, but keys off, cover the two sensors for a few seconds with your palm, that always gets my keyboard lights to come on.
On the DROID pro there is also a light sensor in the upper left corner.
I experienced the same issue that u did. I then put my finger over the light sensor and the backlight came on.
It seemed to stay on from that point forward in the dark.

1. are you rooted, and did you get the specific app mentioned.
2. did you completely miss where TWO of us have mentioned that covering the light sensor briefly usually turns the lights back on?

1. I'm currently on Rooted TBH Gingerbread.
2. Tried that, didn't seem to work.

Thank you!!! it works great now with that app.
hey all, recently added GB to my BF's non-rooted DPro and he's having this issue as well.
Looks like the best, and only, fix may be to root and add that app from the market?
Upon covering the sensor at the top the light does come back on, but only for a second or two. Have messed with the display and brightness and power settings but nothing seems to keep the backlight on when typing.

LED not working as well after Gingerbread update

i was an early adopter of the Atrix and i've noticed that ever since i've been on a gingerbread ROM, the LED won't come on while the screen is still on. this is extremely annoying since it used to do this on Froyo, and i've even tested it in Handcent and it says our phones won't allow it.. has any one else experienced this?
Let the lightflow.
I voided my warranty and your mum.
Lightflow will alow the LED while the screen is on in root mode but then it only does half your colors for some reason..
I only use 4 colors. It works for me screen on or off. Except when testing. Screen has to be off.
I voided my warranty and your mum.
Funny, cause i don't recall the led EVER blinking when the screen was on. I mean... why would it have to? If the screen is on, you more than likely have the notification bar right there to tell you what's going on.

I don't remember that either. (LED staying on when you turn on the screen)
The only thing that is different for me is when I was on original stock Froyo compared to the update afterwards.
The original stock kept the LED on forever, and the update definitely shortened that. I used to like looking on the nightstand to see if the LED was on, now it kinda defeats the purpose of it...

well maybe you don't get enough notifications to notice but it actually makes plenty of sense to blink while its on if for example you are playing a full screen game with haptic feedback turned on and you can't discern a text vibration from the game and you'd like to know if you got a text
