Menu Lights on the Evo

The Home, Menu, Back and Search buttons are suppose to light up. But they aren't what gives?

It might only light up in dark places, I know mine isnt lighting up right now, but it has before.

There are some people who's don't light up, go into the closet and see if they go. Of course then you have to come out of the closet eventually

This happened to me. The lights stopped working all of the sudden... and then randomly started to work again. Don't know what the deal is.

They don't seem to light up when charging.

I noticed this too. If you unplug the phone they should turn on.

I thought you had to be in a dark area cause mine works only in dark places. Sort of like ny work blackberry same thing they light up when its dark.

Just confirmed it. There's an ambient light sensor on the right side of the HTC logo. If you angle your phone right in the light you can notice it....

Hah, you're right... I just tested it too, I turned the corner lamp on in my room but the button lights kept lighting up when I waked the phone... I walked up to the lamp, waked the phone up while it's facing me, buttons light up, wake the phone up while it's facing the lamp, buttons don't light up. I'm not sure I would've noticed that if I hadn't read thru this thread, heh.

Anyone know a way to turn these off for good? It's a bit annoying/distracting when watching a movie in low light...

Touch keys NEVER turn off (even when the phone is off)

My touch keys (soft keys) never turn off. Even when the phone is off. When the screen is on they work as they should, meaning that they do turn off completely after not touching the screen for a while, but as soon as the screen turns off, the buttons turn on, and not full brightness but dim. This happened when i started deleting bloatware, but i have already installed different roms and same problem happens. What can i do? Are there any drivers that i should check for the backlight of these buttons?? PLEASE HELP!!!!!

Do you have a text message everytime you see em light up? You might have BLN on... What kernel u running?

Sorry about that. I already did, but since the developers are always hanging around here i thought i would get luckier.

Check your display settings. There are options for the soft button lights including "always on."

Even when i put the setting for always off, they would stay off when im working on the phone, but i soon as i turn of the screen the touch keys come on and stay on in a very low dim.

is there any piece of code i can flash to force the touch keys to turn off?

This is for development only.not Q&A or any general.mod please move
From a glaxay better than yours.

Has anyone figured this out? Same thing is happening to me and it's annoying.

It's probably your imagination. The brightness from the screen cancels out light (the light that actually is reflecting off the buttons, not coming from the buttons) coming from the buttons when they are "off" as you use the screen and instantly or slowly come into vision as you turn the screen off. When you turn the screen off, there is no light to cancel out the light (sun's rays) coming from the buttons and you can see them. To test, go into a room with no light at all and turn the phone off. If the dim light from buttons are no longer visible, then it was just your imagination.

You dug this out the grave

Me? I just tought I'd put my thoughts and observations out there and help the guy. I didn't dig up any thread if you are talking to me.

Thats how i knew the lights were staying on, cus when i went to sleep i noticed the lights were still on. This is not visible if there's other light sources around you because the buttons light up very dim. You only notice in a completely dark room.

Did you change your settings? If that didnt work, try taking it to a tmo store.

Screen on issues using Lightflow?

This is the second time on 2 different roms that somehow my phone has been stuck with a black screen and when unlocked the screen stays off. Its a bit hard to explain but pressing power lets the screen to come on for just a second but then it goes off...yet on the black screen you can slide it unlocked (screen stays off) A reboot goes back to the same issue. after many button combos the screen will finally stay lit. The only way I have found to cure it is to uninstall lightflow. (Im really not sure thats what is causing it) If you dont change anything when you lock it your right back into the black screen thing..... Anyone seen this using lightflow or not??

I've had this problem to. I had it when I was using the phone on stock without lightflow, as well as using it with HD revolution and light flow. I have no idea why its doing this though?

I had this problem when I used the app "Wave Launcher". I found the most effective way to keep the screen on is to call the phone, stay in the call, and uninstall the app..

Are you running the 350 mhz idle mod or UVing? Seems like your phone isn't getting enough juice.

I emailed the dev's a few days ago. They came back with the response to uncheck "s6e8aa0 control", which I believe is disabling access to the main screen. I haven't seen the sleep of death since. He also said to look for a future update which removes this option.
Hope that this was a helpful first post!

I have the same problem today! When light flow is active the screen goes on for a second and then stays black.
Sadly I can't find "s6e8aa0 control" in the newest version. Can anyone help?

Got it working. I should use the correct settings^^
But the program is not working how I would like it :/

Anything makes the LED besides the front facing camera stay continuously ON?

Today I noticed a dimly lit red light from the second dot to the left of the front camera staying continuously on even when the display is turned off. I am not mentioning about the notification light that is placed to the left side. I tried many options but it stayed dimly lit. Later I thought of restarting the device and that did turn it off. This did show up as bright red for a moment when I turned on the device which later turned off.
Any idea what made it stay continuously on?

I was having similar problem with gs3,turned out to be viber I guess...uninstall it and report again.

I don't have the viber app installed. By the way what is this led called and what is its function?
Thanks
Sent from my GT-N7100 using xda app-developers app

If its not the proper led then it must be proximity sensor(uses infrared light to detect proximity)
Normally turns on when u get a call to turn of screen when u hold close to your face.if its not viber then it might be what's app or Skype god knows what(may be try freezing phone apps one by one and find out for yourself)

Its not a bug or anything. Its meant to stay lit this way because its a proximity sensor.

turn off smart stay and anything else you might not need and it will go away

turn this off by go - Setting>Motion> Quick Glance: untick :good:

As I said it went off by restarting. I don't have the problem now to check any solution. Just was curious to know what was it.
While it was on, it stayed on even during the call or even when the display was turned off. I did not have any motion setting enabled.
Thanks everyone for your kind replies. I will see if I get the problem again
Sent from my GT-N7100 using xda app-developers app

I noticed that too, then I realized what was causing this. It's the Quick Glance function on "Motion" that's triggering this, because while the screen is off the phone's proximity sensor checks whether or not you have your hand in front of the screen for activating Quick Glance. In order to do that, the sensor must continously stay on, hence the continous red light.

Difficult to turn on screen in dark

Has anyone else noticed that when in a dark area, pressing the main button will turn on the screen but it will then automatically and immidiately turn off?
Several times I've gotten into a battle with the phone only to lose, turning it on and it turns off, then turning it on again and so on...
To compound the issue, in these situations it seems that double tap is signifigantly less responsive to activate the screen as well.
I'm pretty sure this phone is using some sort of facial recognition, it has smart stay doesnt it? I think it has gravity/accelerometer to turn on the screen when you pull it out of your pocket. In the back of my mind I'm thinking that since it cant see me it is shutting off but this doesnt seem consistent...
I'm running stock rom, rooted with twrp. Any ideas?

I have not experienced that. Did your G3 do that out of the box?
Sent from my LG-D851 using Tapatalk

Never heard of it. Screen is set to auto off in 30 seconds. Change it to 2 min and you should be good. If u running without a case then maybe the hand is touching the edges of screen this will also shut screen off in double tap.
BAD ASS G3

I didn't notice it until the last week or so. but I kind of feel like that was because I hadn't used the phone that much up until then. I didn't make any major changes to the phone immediately before I started noticing it either, I had already had it rooted for about a week. I feel like the stock rom does have some glitches to it.

The G3 does have a "smart screen" feature that detects your face (Settings > Display). Disable that and see if it helps.

I've not run into this in the dark but have when I try and use my arm band holder when running. The holder covers the ambient light sensor so the phone thinks it was accidentally turned on like in a pocket and shuts right off. Super annoying.

Noticed similar behavior when the phone is in my bike mount at night. Basically it's acting like the proximity sensor is covered. In my bike mount's case, it is covered by a clear screen cover, but normally that doesn't trigger the proximity sensor. But when it's very dark out (not under a street light etc.), it seems to think it's blocked and turns itself off. Annoying.

Tried but remains the same... This was the only thread I found concerning this.

Ive had this issue too investigating now

Had that issue when I was using the lock screen face unlock. In the dark it didn't see my face and then it shut off. Setting is in lock screen section

Lol.

I have the same issue EVERY night. Why is that? It's very annoying

Same issue here
it seemed to resolve itself when I factory reset my phone
but after I got my apps reinstalled from my google backup it started again
so it seems like it's a software issue - not sure to which app it is related to
let me know if you find a fix - this is quite annoying

Me too. I've been facing this issue at night, when it's very dark.
Me and my buddy were in the car during a roadtrip and it was very dark, I mean like: No lights outside, no lights inside the car, the double tap feature didn't even work to begin with and whenever I tried to use the "Power Button" It would come on and then suddenly 'boom' Turn off, now this would happen a few times until it stays on. Weird...

I just experienced this myself, first time I've seen it happen in the 30 + G5's that I've sold. If it's in the dark it just doesn't turn on at all. I hope LG is fixing this. I'm about to Factory Reset it right now and hope for the best! Someone else mentioned that this is the only forum that is disccusing this issue. It must be a very few that are effected. I'm testing another one as we speak.

Has this issue been resolved? My friend's G3 also has this issue. Day time no problem. When it is dark the screen wont' stay on.

Same problem, no fix yet
Same problem here - Pointing it at any light and pressing the power button will turn it on. (As will plugging it into power). Tried tinkering with all sorts of settings (face recognition/auto dimming feature/etc) nothing worked. Tried factory reset, that didn't work either.
My issue started after i had my screen replaced (by a shady shop) who probably didn't do a good job of packing it back together....I'm going to see if I can have someone open it up and clean it out a bit..

I have the same issue on my G3. Even if you're under the covers in bed, the thing doesn't turn on until it gets light. It basically doesn't turn on in the dark through double tap and actually not even with the power button. It could become a safety hazard for someone in an emergency situation.
