[Q] HTC One (m7) Green LED not working

I currently have a stock HTC One in Canada on the Telus network.
The last few weeks i noticed the LED light growing dim. About a week ago the phone rebooted itself only to say it had an issue and that it was not shutdown correctly.. and asked if i wanted to report the problem to HTC.
The phone the froze with the Screen on but a black background.
After 15 minutes i powered off the phone.
At this point the phone would not power back on.. when i plugged the power in to the phone from the wall the phone would not indicate that it was charging via LED.
I tried booting no response.. no vibrating,.. just slight flashing lights on the Home/back buttons
I ended up booting up the phone by shining a bright light into the light sensor while holding Power and DOWN volume..
Phone has been working fine ever since, however still no LED.
I did a factory reset and still no LED.
Has anyone see anything like this?
I want to root and install Google Edition Android however if the hardware is faulty i dont want to risk voiding the warranty and being stuck with a faulty phone.

This has happened to me too. Just one day noticed no led light anymore. Strange thing to break down on a phone! Have you had any joy in getting a fix?

Unfortunately I have not been successful getting the LED back.. I am debating sending the phone in for Warranty work... or just sucking it up and rooting/flashing custom roms.
My main concern is that there may be a bigger hardware issue going on internally.
I'm really just trying to get a feel of how common this issue is..

Try this: in dialer type *#*#3424#*#* (3424 = DIAG), that will bring up HTC internal diagnostic, there's a "LED Test", select and run it to see if it's a hardware defect or not (you will get Orange and Green LED tests).

Thanks for the info.. Just tried it the LED test .
To my surprise the Green and Orange lights actually show up but I have to hold it to my eye and block out any external light to see anything.. kind of defeats the purpose of an LED notification light..
I guess the light works its just extremely DIM.
Any way of controlling the LED light brightness?

Don't know, but I just ran the same test in a very well lit environment and the Green and Orange LED are quite bright... I don't have to "go look for them" they pop out nicely.
Are you using a cover of any kind? Or maybe the LED has somehow shifted it's position and is being partially covered by the speaker grill? Hate to say it, but sounds like a hardware issue. Sorry
Hope someone else has other ideas.

Not using any case that would cover the LED.. that being said even with the Case off.. the LED is still very dim.

Hmm tried and then the screen just refesh by no diagnostic screen at all..
Not sure is my custom ROM affecting it.

Shouldn't affect it. I've been using ARHD 9 through 13.3 and works with all of them.

I've ran the LED test, and all of them work. But they dont light up for notifications, and i have it enabled in the settings.

I have the same problem. Did factory reset two times. Red when charging, green when full but no flashing green for notification. I enabled it in settings.
Have you manage to find a solution for the problem?
Thanks.

I am having the same issue! The light works, but it doesn't blink for notifications!!

I also have the same problem: when it is charging and when it is fully charged the light works OK but doesn't flash for notifications. But it worked OK some time ago. Actually, when I think about it, it seems that the problem started after I had updated to the current firmware: Android version 4.3, HTC Sense version 5.5, software number 3.62.401.1
It must be issue with firmware/software because LED test works fine.

There's another thread similar to this one and someone there figured out the solution - you do a factory reset but, when the phone reboots, you do not restore everything using your Google account. Go through the setup as normal (without restoring) and once that is complete then you can add your Google account details.
It means you have to download and set up your apps again, but it is worth it to get the LED working.

HI I had a similar problem I cleaned out the hole with a needle and all is well, pin came out dirty (the one on the grill dirt was blocking led )

LED under the earpiece?

I have had the phone for about a week now and I love it, however one of my big complaints is that the active notifications do not show any battery info, charging or percentage blah blah blah. My phone died the other night and when it was plugged in it had a bright green LED under the earpiece. Any other time I've plugged it in it has never come on. Does anyone know why it would come on one time and never again? Has anyone else seen this elusive LED?

I saw this on a display model at ATT with a dead battery. The earpiece was lit by a green LED.

maybe try lightflow?

I thought the same thing, and I played around with it a little and couldn't get the light to come on. I'm just curious because motorola made the point that LED's don't give any information like active notifications give, yet they still put one on the phone. It just appears it barely ever comes on.

We definitely need to figure this out!

Never seen an LED on mine, but very interested in this. Would be awesome to enable it!

Anyone figure this out? I saw the same light under same circumstances but can't control it.

LED Light Answer
Found the answer in the owner's manual, of all places, on the page "At a Glance" with the illustration of the phone's features. The arrow in the diagram points more or less to the sensor right next to the earpiece. That small oblong is not just the light sensor to turn off the screen when you have the phone up to your ear. It also houses the Low Battery LED. Sometimes it really does pay to read the instructions, however boring they may be.
Low Battery LED:
This LED lights up when you plug in your
charger and the smartphone’s battery level is too low to
power on the display. It means that your smartphone is
charging and will be ready to use shortly.

Knowing that Motorola's way of Notification LED was their Active Display, it would be redundant to have the Notification LED too.

Even with root there's no physical way to enable this light in other circumstances?

I emailed LightFlow and got this reply:
Hi
Sadly it doesn't really have much led hardware in it. There's one
green led which I think can only be controlled with root access from
the experiments I've tried with a user.
Cheers

I'm pretty sure it was confirmed that the LED in the earpiece was connected directly to the charging hardware found on the MotoX. What does this mean? It means we will probably never be able to take advantage of it. It's nothing the software can take control of.

Just to throw this out there, will this work?

Oh well, worth a try!

Has anybody seen light bleed like this?

Looks as if I'm going to have to join the return game on this device. I've been a very happy TF700 owner on CROMi-X for the last year and still had that WOW effect when I started playing with this tablet.
Until it got dark.... I mean - the attached picture is with the tablet in sleep mode!!!!! That's gotta suck the battery dry like nothing.....
Opened a ticket with Asus for what it's worth...
I'm going to update to 4.3 manually, but don't expect that'll do much.
Does anybody have something similar?
Edit: After about an hour of reading the screen dimmed and had dark shadows on both sides. I flashed the 4.3 update manually since the System Update wouldn't - now everything seems to be fine.
Light bleed gone when in sleep mode and no shadows either... ?????????

Weird, glad you got it sorted out.

Unfortunately it's not resolved to the point that I feel confident to unlock.
I still have have weird and uneven dimming of the screen. Sometimes just part of the screen dims and shows a dark, uneven shadow across it (in reading mode). What I don't understand is, taking a screen shot in that situation shows nothing of the shadow....??
What I consistently see is when the screen times out, it dims just before it turns off, but only on part of the screen (more or less the left half, but fading out from left to right).
Smart Saving is off.. Can't think of anything else to try...
I'd hate to return it, but I think I'll have to - this does not inspire confidence....

Smart saving has nothing to do with smart dimming unfortunately. You can only turn smart dimming off if you are rooted. I'd take it back and get a replacement as what you are seeing is not normal.

Never seen this on any tablet.
To me it seems that some parts of the Led backlight are not working correct or totally not.
Better try to get it swapped or Rma'd ASAP.

R.I.P
I was filling out the Amazon return form and picked it up 'cause I got a notification about new mail - and that's when the digitizer gave up completely.
I was able to wipe my data by hooking it up to the TV and got it to reset with a lot of huntin' and pecking.
A replacement is on it's way. You gotta love Amazon :cyclops:

Brighter notification LED ?

Hi, I think that the notification LEd of our HTC One is really poor. It really small and also not very bright, so it's very hard to see if you are not in a dark place.
But I noticed that when the battery is empty, or nearly empty, and you plug in the charger with the phone turned off, the LED is much brighter than usual.
So I wonder if it would be possible to make a hack for increase its brightness for every notification.
Thanks!

+1 here. No solution yet...

My led died last December. I don't miss it. But I was on the search for a brighter light too. I know that there are some hacks but I don't know exactly where and what.

Are you sure it's not just covered with dust or something? Try cleaning out with a toothbrush, some people "recovered" its led and loudness after cleaning

Yeah I'm pretty sure. I cleaned it very often it's dead and I don't care anymore. It's not worse to me.

Okay, I fixed my LED brightness.
It really was very very dim in phone's standby regime. Entering the bootloader or and other on/off procedure was setting orange led ON FIRE! That means there is a lot of power getting lost somewhere. In the /system/sys/class/leds/amber and /system/sys/class/leds/green there is a file named "pwm_coefficient" that determines LED's strength. I was unable to edit it on my (stock 5.0.1) kernel, but somebody may be able to do that, and alter the default value of "5" to something like "255" which I believe is maximum.
Anyhow, as a last resort (being so frustrated not being able to see my notifications on time) I decided to physically clean the LED's hole. I used an extra spiked toothpick (just give it a nice touch with a sharp knife, to make it super pointy and thin) and stuck it inside, rotating vigorously. It turns out that was it, it's as bright as new.
Still I wonder why dirty LED was shining brighter prior to boot?

Auto brightness.

Anyone here turn off auto bright, set to max, and see it is still running?

Should be a little arrow at the end of the slider and click that and turn off some settings. I thought I had turned mine off as well til I fooled with the setting. Now I'm good.

Was outside today and noticed screen would light up a bit and back down while under tree. So I tested by putting hand over sensor. Inside it doesn't change no matter how light or dark the room

Yeah I was talking about in the drop down. Maybe turn the brightness down a bit instead of full brightness?

Maybe turn auto on then off and reboot your device.

I don't do well with dim light set, even in a dark room. Puts a strain on my eyes. Always full brought. Might have something to do with note 7 mess, not sure. This is my first non htc device. Just used to all the way up, being all the way up. Brightness doesn't change indoor at any light levels. But this does in brought sunlight, and I put a flashlight into sensor and it got brighter. If it is available, I want it all the way up, no holding back.
Also used to having a dead battery by 1-2pm, but with this device, 10pm I'm looking at 40-60% and have been using it more than old device. Of course, to me, that is mind blowing. I've seen reviews complaining about poor battery quality. They should get a htc one m9.

Yeah the battery life is definitely better atm. Im not doing too bad.Hopefully it stays that way.

Has anyone found a solution for this? It drives me mad. I also want 100% full brightness at all times. My auto-brightness is also turned of as well as Adaptive settings under Display yet the brightness still adjust when moving in and out of brightly lit rooms or in to the sunlight and back in to shade.
I have been searching all around to find an answer and everyone thinks that I am just talking about the Auto-Brightness, it seems to be an extra "feature" and I want it disabled.
Let me know.
Thank you
