So, I am not sure in anyway how much power the LED flashlight takes at any of its intensitys, but is there an app out there like NoLED or even BNL that could take advantage of your LED Flash.
i set my phone down , usualy face down cause I its pretty reflective.. so this would be really cool
I don't think it's a good idea, the flash is very bright and you might hurt your eyes
Pretty sure the flash uses far too much power to make this an option.

well.. the flash is not that bright all the time, there are several steps that the flash seems to have.. so it is possible..

I can't seem to find a thread on this and I find it hard to believe no one else has an issue with this. In the camera on the HTC Touch Pro where the flash option is, it's "flashlight" not "flash." So you can't have the flash bulb turn on only for the picture and then turn off like an actual camera flash. What's the reason for this? Any hack to fix it?
If you use it how the Touch Pro seems to want you to...
You may as well admit the LED will burn out before it should.
i don't think the led will be burned anytime soon. have never seen a burning led. if it last for 2 year i'm happy, i would probably go a new htc by then. however i agree that having the flash turn on like that it's a waste of battery.
you know the funny part about this is i'm actually this flash as a flashlight with htctorch and it has been very useful.

Yeah, I've searched for this myself, didn't find anything. I mentioend something about it somewhere else but got no responses. Probably because the phoen was brand new and maybe not widely used yet.
In any case, LED's are rated for 100K hours of life, some may get more others less, but on average, that's their rating. Long past the noral usage of a cell phone. It does actually flash though when you take a picture.
The reasoning though (guessing) is if it's in a relatively dark room, the camera will be unable to focus properly to take the picture without it (the subject) being lit up before hand. But most people probably don't take pictures in that dark of an enviroment.
In any case, it would be better to have the actual option and let the user decide if they need pre-light or just a flash to take their picture.
hmmm.. yeah, its not a flash, its a flashlight. if anyone wants to make a hack for this to just flash, that would be so ****ing badass. that thing is so bright that peoples eyes are always squinted before the camera even focuses. its nice that its bright, but i mean, seriously.... its BRIGHT. and annoying.

+1....I was wondering too
There's a reasoning for this, at least.. the focus and metering mechanisms all function poorly in low light, so without the light on for the focus phase of the image taking, your photos would come out even worse.. it isn't the only phone i've used that behaves this way, almost any phone with a LED flash will do this, only Xenon flashes and the like will behave like a camera (brief flash on shutter release)
can Mozart's Xenon flash serve as flash light? I read some review that LED can stay on but a xenon can't since it's like digital camera flash, it fires once after it has sufficient charge. To those people with units, can clarify on this ?
I don+t have the unit, but flashlight app from HTC is not available on the Mozart (check HTC website for instance). I don't now if 3rd party flashlights will allow this, but what i know is that xenon flash must not stay on because its powerful that LED and eventually may burn the flash... So LED may be used for flashlight, but xenon no.
No, it cannot. I bought a powerful LED light from DealExtreme for my keychain to use as a replacement as I was used to the HD2 LED flashlight
There are a few apps for the HTC 7 Mozart. But they only make the screen bright! In my oppinion thats pretty useless...
Yeah, Xenons cant light up permanently. They physically just cant.
And using its display as flashlight sucks.
I read that the flash can only be used for short periods of time as its an Xenon bulb and will burn out if used for to long.This would also explain why know one has made an app for this. The screen light apps are no good but thats not the fault of the app makers as if they could do some thing with the flash im sure they would do. Its almost as important to have a touch as it is a alarm these days and we have all kinda come to expect it. Hope this helps.
The xenon flash is driven by a flyback converter (in the same manner as a capacitor, sort of) running voltage of around 200 - 300v, as the naked battery power isn't capable on it's own... The reason it can't be used as a flashlight is basically due to the converters recovery rate...

true, its kinda important, all i ever read was how awesome the xenon flash is but never a word about its disadvantages untill i got one. well i can live without light, always got a lighter, or consantly take pictures like in some horror movie for light
then i read this nice mozart review and about the camera
http://www.missuall.com/htc-mozart-2/
The xenon flash on the Mozart is a bit of a joke. First of all it is too weak and is only usable in low light at a short distance. Attempts at using it as a fill flash with day light were met with spectacular failure. Apart from being weak, there are also three more reasons why the flash fails to perform adequately. First, there is no focus assist that would help the camera focus in pitch darkness, which means your images would come out of focus. Surprisingly though, it worked quite well in low-light.
Secondly, the camera cannot judge the distance of the subject from the camera and modulate the intensity of the flash. Objects that are closer often get washed out when shot using the flash. Lastly, Windows Phone 7 is not optimized for a xenon flash but an LED flash, which means it uses a slower shutter speed, which does not work well with a xenon flash.
Since the shutter is open longer than the duration that the flash is active, the camera is unable to freeze the action the way you are used to seeing on other xenon flash enabled cameras. This is similar to the slow synchro mode that some cameras have where the shutter speed is reduced to allow more light in, except on the Mozart, that’s the only option you have.
We also had issues with the accelerometer on the phone, which annoyingly recorded the orientation of the images incorrectly. Even when we were holding the phone perfectly horizontal it would save the images in portrait mode, upside down. Because of this, we always had to make sure the camera is perfectly straight before taking an important shot, lest we took our pictures upside down.

so i think in future the xenon flash can and will be supported by apps and then it will totally rock!

sounds like you got some internal knowlege about, so is it possible to flash with the xenon more then one time ? how long is the recharge time, how many times can you flash in lets say 10 sec? if u cant make it always on, try to make it flash 24 times a sec i kinda think it wont be possible, but then cant we have multi-shot pictures? i wish i could view in future

xenon lights use a ballast to constantly supply the required power demands of the light, vehicles have an inexhaustable power supply for this process...

The phone flyback converters are produced pretty much with two goals in mind:
1. be small enough to fit into the case...
2. supply the demands of a low-tech, low demand camera...
I think even if you could overcome the dependance of the flash to recover only in line with the frame rate of the camera, the battery would not be sufficient to run it as a torch/flashlight for long...

So we can't use the xenon flash also during video... grrr
This is one reason I am strongly considering the cheaper Trophy over the Mozart. The Mozart has a better build but if you plan on doing anything involving flashlight capabilities then you will be better off with a Trophy.
You could buy an external keychain light but to hold that and keep the phone steady will be a task.
I know, the blue lights between the physical keys on x10 look pretty, but they drive me crazy when I try to use the phone at night. the lights are just so much brighter than the screen and they burn into my eyes, is there any way to turn it off? Don't care if it requires xrecovery or flashing

Use the custom 2. 2 aosp Rom. The led lights are not working. They work when you first turn on the phone. But once you go to lock screen it won't ever turn on. Be careful when creating new threads like this. A lot of people here will give you a hard time. Next time find a relevant thread and post there.

Is it just me or does the led notification light seem very low? If the phone is laying down flat it's very hard to see if your not lookin at it directly is anyone else having this issue as well?

It is very dim and the color is dark. I barely ever notice it.
we have an led? :O
but seriosuly its dim and small, my old epic is by far much larger led and much more noticable

I consider it a feature..I can accidentally set my phone face up at night without a notification lighting up the whole room and waking me up. It's all in how you look at it I guess!

I agree that it's not very noticeable and I like being able to see it. One of the smaller issues I have to complain about right now though.
i agree, does not light up the whole room. My old EVO used to do that. uggg
I want to know when the light is going to work at least how it says in the manual
Okay thought it was only me. Yeah other than that I love this phone especially how fast it charges!
Yeah I thought the same thing when I first got my photon, I don't mind it though, and your right it does charge super fast,

Well, until you mentioned it.................Yes, its low unless I'm actually looking at the phone (and this likely saves battery?) BUT, as stated, I dont want my bedroom glowing when I'm sleeping either. Not like I would get up and actually check it anyway!
on old gingerbread phones without led notifications there used to be a kernel maybe Franco don't recall that had the ability to flash the capacitive buttons. That would be key on our G anyone know if its possible?
from my Nexus7 while my Optimus rests
Bln support. Built into kernel. Then the app will work
the best phone ever
Yes that was it I remember the app and the kernel dependency now if someone would do this lol
from my Nexus7 while my Optimus rests
Crazy enough there is an app that can do it. It's working on mine. You wouldn't expect it to work though but it does. The app if Light Flow. You have to enable the app to control the buttons light. It does work but seems to cause a full wakelock.

From my understanding that only Samsung phones can use bln. But on another note why would you want that when we have a very bright led on the power button?
Edit: while that would look clean with the front buttons for notification that would give some drain battery drain not worth it to me since we already have a led light for notification. While wouldn't be my first choice for the location, they should have done it like the sprint model.

Aside from the side location, the other issues with that notification light are 1) the fact that it only blinks ever 30 seconds or so, with no option to change the frequency, and 2) instead of an RGB LED, apparently LG only put a red one in, thus making it impossible to differentiate between different notifications.
If frequency can be fixed, I'd be happy. Otherwise, getting the capacitive buttons to each indicate a certain notification seems like a great alternative.

There would be so little battery drain you would never notice. Also, if you turn off the red led and only use the front capacitive leds the "drain" would be equaled out. I used BLN before and it is amazing. Would love to see it on the LGOG.

Well I notice it blink every 5-6 seconds for a minute or so. But in a dark or lit room I can see it just fine. Only thing I don't like that it on the side should have been on the front like the sprint model. And still don't see why they made the phone different anyway. Just glad the att model has the sd card slot
