[Q] Does the Desire Z/G2 have a Green LED ?

Hey xda
I've had my Desire Z for about two months now and damn its the best phone i've ever had ! However i noticed something the other night which i would like to ask you about.
I have no green led that blinks every 3 seconds or so at the top where the speaker is. Shouldn't there be that when the phone is having reception ? I noticed this when i was charging my phone.. The older HTC's i've had usually glows orange when charging, but changing to green when its done charging.. But mine just turns off the orange led so theres no led litten up at all
Is this normal for the Desire Z or what does your DZ do ?

I have a G2, the charging LED goes from orange to green when it is above 80% (I think), but it isn't used at all outside of charging.

the green LED blinks when you have messages waiting or emails etc. as well as full charge indicator.
It really depends on how you've set your notifications up.

Is there somewhere i can change if the Green LED should be on or not ? Or maybe test it .. Because i never see this Green LED on.. When charging is done the orange led just turns off and no led is litten.. The same goes for when theres reception and i have a message.. The Green LED is not blinking at all

definitely sounds faulty to me. The only app I have ever heard rave reviews about is LEDme. Give that a try to configure the notification blinking. If that doesn't work, dig out your receipt for a return.
EDIT...... As Steviewevie has stated... App is called LED Me Know. My mistake.

The LED doesn't blink for notification unless you use an app (e.g. Led Me Know) or an app that does that for you.
In the stock DZ ROM, the trackpad itself blinks when you get a message, if that setting is switched on, though the blinking is very slow - e.g. every 10 seconds or so.
The LED in the speaker grille should turn green when the battery is fully charged. But when the phone is new there is a "learning" process for the ROM/battery, so that might be why you are not seeing it yet.
If you install the "Led Me Know" app (from the Market), there is a function in there to test out the notifications, so you could set it to use green and then test it from within the app, just to make sure your LED shows green ok.

The free app "Missed Call for Android 2.X" (there is another version that is just for Android 1.6) works well to change the LED notifications as well as vibrate patterns. I just tried it, and it works for flashing the green LED for a SMS notification.

Or if you only want to test it, download "covedesign dev"

Thanks for all the help guys .. I tried various of your mentioned apps and none of them seems to be able to make my green led glow.. Just wondering if i want a spare or not, since it just a rather small fault.. Do you think they will replace it ? is it enough faulty for them to fix it ?

If its supposed to have a green LED, and the green LED is broken, then I think its justification for a replacement.
Whether it bugs you enough to replace it, that's your decision. The only time I've seen it light up (without changing the settings with the Missed Call app) is when charging is done. So it really doesn't have much use, anyway.

Arc LED Notification light.

I thought the Arc had a notification light on the Battery charging light but cannot find the settings in the menu & when i get a message via gmail, there is no light just a notification in the bar??? Does anyone else get a flashing light if so any idea where the settings are.
Cheers

Just did another test & the led light does flash. But when you press the power or home key (which displays the lock screen) the led stops flashing which is silly as you can easily press the home key in your pocket.
Is there anyway to leave the led light flashing until you swipe & unlock the phone, or to disable waking up the phone by pressing the home key.

i think Led always stop flashing after the screen comes on. This was also on my nexus. didn't com across something to keep it flashing while the screen comes on.
Anyways i don't like the led location, i never see it.

Agree Stupid place to put it, but at least it has one unlike LG & Samsung phones. hope it is possible to stop the phone from waking by pressing the home key though.

I want programmable notification lights like the X1 had.
My X1 still works, but it lacks any decent software to make it work well.

I love it! I ordered a PDAir case with a cutout for the light so I can see it witout taking it out of the case.

Anyone tried Light Flow app?
I hope we can use the lights of the buttons under the screen as notifications too

This was exactly what i was thinking of, it would be great.

That would be BackLight Notification (BLN) it exists for samsung phones that doesn't have a LED.
But it needs a modified kernel to work. So we have to wait for SE to unlock the bootloader and someone to adapt the kernel for bln to work.

It's possible in a cyannogen mod rom under led setting... we'll have to wait for custom roms to use it that way..

At 3:00 Minutes.

has anyone found a way to make the 2 LED lights work for notifications?

Any news on this topic? Will it be possible without rooting the device?
Would be perfect if I can use the front-leds of the device for notifications.

[Q] GNex Led

Heya! I thought i'm gonna ask this before calling service or something. The problem is (yey!) notification led.. I've tried enabling/disabling it from screen settings and from light flow (paid and free versions) and i haven't seen any life from it. Led testers and everything else gives same results.
Someone has another test method for me or am i forced to call for Samsung?
Service company told me to call Samsung (ROFL?)

Hey this may be done already but when you test the notification in lightflow did you turn the screen off?
I know lightflow will only work and show test notifications if the screen is off. Sorry if you did this already but I thought the same when I got my Nexus.

Yea i tried and rebooted phone after installing/uninstalled Lightflow versions and vice versa. Seems like its completely dead

Weird. If your rooted I would unroot and go back to your carrier. They should replace it. Good luck

Easiest way to see if the led works is to look at the phone while it is receiving a call. The LED should be lit solid white while the phone is ringing...

[Q] Light flow/LED problem

I just switched from a Nexus 4 to a HTC One M8 GPe. On the Nexus 4 I used Light flow very much with many colors and blink patterns to be able to identify what was happening without turning on the screen. Now when I have installed Light flow on my M8 it's only possible to choose from 4 colors or something and no blink patterns.
Is this possible to fix?
Great phone but this really bothers me...

Someone can correct me if I'm wrong, but I believe that it is due to the limitations of the LED on the M8 vs the N4. It's a different type of LED so there isn't an ability to tinker with it as much.
I miss that from my N4 too, but ultimately as soon as I saw/see a notification light I check the phone anyway.

I suspected this but before I got the M8 I didn't even realize that it would have anything else than the best LED. But yeah, 90% of the times It's just a message of some kind so I guess I'll survive. Still annoying though...

Not only is it not possible to fix because of the limitation of the LED that the other poster mentioned, but I'd be shocked if Light Flow gives you any color other than green and if it works consistently.
I had messed around with it some a couple of weeks ago, and gave up. I guess it's possible the Light Flow developer has tweaked it since then, but the version I was using was pretty useless on the M8. I don't fault the Light Flow developer though. I blame HTC on this one.

I was able to get green and amber to work. Some colors would just pick green or amber, others just wouldn't do anything.

Yeah, it seems to work pretty bad. Are there any other ways to control the LED like Light flow? Does it work better if you just let all the apps control it themselves? I guess not?

I was able to get green and amber to work.

Green, deep orange, magenta and cyan works for me, but green and cyan shows as green/yellow on the LED and deep orange and magenta shows as orange.

Messed around with the LED settings in Textra after I disabled Light flow and suddenly it actually started to blink. Great improvement!
Is it possible to get it to blink in Light flow too?
Edit: Yes, enable color mixing.

Maybe I was unclear. To get it to flash in light flow you just need to enable mix and choose flash under the right color. This is not specific for Textra, but Textra can flash the Led by itself, without Light flow.

I've really tried getting it to work, but needed to put it in Direct Mode to get the LED with permanent light when lit, instead of flashing.
But in this mode the LED is dimmed even though the settings are set to 100% brightness in lightflow.
To get the LED 100% brightness I needed to remove Direct Mode and accept that permanent light instead didn't work, and live with flashing LED. Hence, not very different control than the standard setup i the Sense rom.
Any clues?

Try direct mode, root mode and HTC alternative mode. All three at once.

With that Setting the led is always permanent on dimmed like 20% through mixer and also standard control.

Yes, I had the LED flashing green from Textra, without Lightflow. But the Textra reminder options are so limited, I'd really prefer to use Lightflow if I can get it working properly.

Then I dont know. Works perfect for me. Really bright too. Have you turned off LED notification in screen settings?

I've been fooling around with this a lot since hearing the news that it was working.
I think I've got it working pretty well to my satisfaction now. As I was messing with settings, some of which I may have inadvertently checked (like the Samsung always on setting) I saw a number of interesting behaviors.
One was that at one point my basic notification was, instead of just the green LED flashing, a combination of alternating green and amber colors. (I'm not sure what I did, so don't ask me to reproduce it.)
At some other point I had the LED staying on even with the screen on.
There were other issues, though, when those things were happening. So I kept monkeying with the settings, and I think while neither of those things are happening now, for the most part Lightflow is working acceptably well. I actually would like it if the LED --could-- be on while the screen is on.
Also unless I am mistaken, after an alert, if the screen is turned on but the alert is not cleared, when the screen is turned off, the LED will not come back on. Is this what you two are experiencing as well? I'm pretty sure with my last phone if the alert was not cleared, the LED would continue to flash.
Thanks.

When the LED is alternating between two colors (or more on other phones) it's probably two (or more) notifications and you've got the settings to loop through them all. Standard setting is to do this when you have the charger plugged in IIRC.
The LED is working with the screen on for me and I think it always has on the M8. On my Nexus 4 it turns off when I turn on the screen and the LED turns on again if I don't clear it and turn off the screen. Great if you don't want to read the message right now and still don't want to miss it later. Since the LED is always working wether or not the screen is on, this is not a problem on the M8.
But if it's possible to alternate with both colors on the same notification, that would be a great way to get a third "color". Could you check if it is like I said or if it really is dual color?
EDIT:
I got it to work! In mixer you can set one color to solid and one to flash to get both. So there are actually a difference on green + amber and amber + green. This will give us a total of 6 options: green, flashing green, orange, flashing orange, orange + flashing green, green + flashing orange.
EDIT2:
The non-flashing color isn't very strong, so I'm not sure how useful this really is.

It was definitely not really two notifications, though it is somehow possible that Lightflow was acting as if it were. The alternating was definitely like the alternating LED colors that I used to see on my last device when it was alternating between notifications.
I can't reproduce it because I don't know what crazy combination of settings I had at the time. The Samsung always on setting was probably involved. It's even possible I had incorrect checked the Samsung root mode. I was really trying lots of things, and not sure of what I was doing.
Right now, as you suggested, I have Direct Mode, Root Mode, and HTC Alternative driect mode all checked.
I have all LED notifications turned off in Settings/Display and Gestures/Notification Light.
I have Textra set to not notify me in any way, and am using LighFlow for notifications and repeat notifications.
I have not tested things much, so I really don't know how well it is working, but it basically seems to be, though I definitely do not have the LED staying lit with the phone on, or after I turn it on and then back off.
I wonder if some of the differences we are seeing could be due to versions of the phone, rooting procedures, etc. My phone is the Verizon version, and I used Weaksauce to gain root access. Could this make a difference?
Again, many thanks!

It is not possible to fix because of the limitation of the LED.

[Q] Is being able to turn the LED on when the screen is active a 4.4.3 thing?

I recently switched over to the newly released 4.4.2 stock and, in the process, seem to have lost the ability for the LED light to light up when the screen is on, like I had on some custom ROMs. Is this strictly a 4.4.3 ability, or are there apps which can give this functionality on stock?

Not sure but its another battery drainer lol. I see no point in it unless for a notification IMO.

Im on 4.4.2 and my notification led (the colored led on the Home button) works when I get notifications, but the led only turns on when the screen is off. It doesnt blink with the screen on.
If I get a text message for example, the led will blink when the screen is off. Once the screen is turned on, the led shuts off, but as long as I dont view the text, then the led starts blinking again once I shut off the screen.
For anyone who needs it:
The settings for this are under Display > Home Button LED
There is an easily missable section under there too. Be sure to tap "select missed event" and choose your options in there too.
