making the photo light behave like a camera flash?

Is there any way to make the photo light flashes like a camera flash?
turning it on all the time while taking a photo is very annoying.

dont think so.

Flashlightapp does the trick
it's a widget.

Another app is XPERIA Flashlight: it's an app with timed light-on presets (including unlimited), as well as a widget to turn the LED on and off.

Thanks for the reply,
But those apps is turning the LED light on, not using it like a camera flash.
Maybe I am asking too much.

its not a true flash so i don't think we will ever see real camera flash.

No. That only works in 2.0/2.1. That's why you have to turn it on and off. Hopefully we'll get a "real" camera flash in 2.1.

front camera on htc hd 2

i see in fron of my htc hd2 in left side two small lens is that a fron camera.

No. It's not.

One is a proximity sensor (turns off the screen when it's up against your face during a call) and the other is a light sensor (for the backlight's auto-dimming function)

its how the gov't is tracking you.
actually i'm glad as all the other phones get front face cameras i won't have one, no one needs to see my ugly mug.

Lol awesome first post!

it is an eyescanner? or a whole to feed the pink elephants?

I have some Risperidone for you...

Front cameras will be the cause for many divorces or split-ups...

Actually with any luck front cameras will prevent many people from getting together in the first place

dont think its coming to this country but the rest of the world uses it, at one point last year we were headed in that direction but the minmo7 devices turned it down unless the companies are still waitin to unleash the devices but the network can handel the data

If you want to get real technical about it, one of the holes is a light sensor that is sensitive to daylight for backlight brightness control and IR for proximity sensing, the other hole is an IR led that turns on during a phone call. When you hold the phone next to your face the IR led bounces off your skin and back into the 1st hole telling the HD2 that you have it near your face.
Try this, initiate a cell call on the HD2, then hold a video camera over those 2 holes. you'll see the IR LED lit up. It only lights during a cell call. Even better if you have a sony camcorder with nightshot mode activated, though just about every CCD/CMOS sensor is sensitive enough to IR even with the internal IR filter in place that you should be able to see it
Im going to take a guess that the IR led isn't just constantly lit, but likely pulse width modulated to some frequency the HD2 recognizes that way the light sensor can tell the difference between the IR bounce back and ambient light. I couldn't tell with my camera that it was PWM, but it could quite likely be at a frequency greater than 30hz, which you wouldn't be able to see on a standard video camera at 30fps. you'd need a high speed camera, or another IR sensitive photo diode attached to an oscilloscope.

Awesome, thank you for the white paper I love that kind of stuff!

If it is quite dark, you can see the LED blink about once a second...

Heyy all,
Actually the guy was asking if that's a FRON camera. Yes it is!!!

I think you're looking at the notification led on the far left of the earpiece speaker grille. I highly doubt you can see the IR LED with your naked eyes. Were talking about the two dots under the glass just to the left of that.

That sensor is not a front camera. its a photodiode http://en.wikipedia.org/wiki/Photodiode i guess you could call it a 1 pixel camera lol

Believe me i can tell if it is an LED otherwise I wouldn't be doing my masters in electronics
and to answer your question, it definitely not the notification LED or the light bleeding from it into the adjacent space. when a call is in progress and it is very dark around, you can just make out the faint blinking.

Wait for HD3 to solve the problem just for you

HD2 camera flash can not be switched on at always on mode

I upgraded to the latest ROM version 3.14.831.3 couple of weeks ago, after that I found the camera flash light does not work when switch to always on mode. The flash light would be not on until I take a photo which acts the same as the auto mode.
I have tried the factory reset, which seems it only restore back to the latest ROM with clean settings, but the problem is still there.
Any one has same issue?

Yes, it's the new software version that does that.
I was thinking if we could take the files from the old camera software and put them in this version.
It's annoying not just if you want to use the phone as a flashlight (solved with torch app, but not that handy) but the picture quality in low light conditions totally sucks, because it won't focus when the flash is on.

This is by design... it's SUPPOSED to behave like that! The way the flash illuminated constantly like a torch/flashlight in the old ROM was very annoying... it wasted battery power, blinded your subjects and was distracting for everyone else around. You won't find a conventional 'proper' camera exhibiting this behaviour (actually, they can't anyway due to the way xenon flash tubes work).
The new flash behaviour in the new ROM mirrors how a conventional camera would behave and, IMO, is a big improvement.
As for focusing, I've never had much of a problem and think the HD2 does a very good job in low light most of the time. The only real solution to accurate low-light focusing is an IR focus-assist lamp.

If it is by design, HTC should disable the option in the camera mode to have the flash light always on. And also disable the flash light in the Camcorder too, it works totally fine in the Camcorder mode.
Plus they do not mention this change in the ROM description.

I think you're misunderstanding how the camera app is designed to work... when you select the option to force the flash on, you're telling the camera app to always fire the flash, regardless of the ambient light level. The flash LED is not supposed to stay lit the whole time that 'force flash on' is enabled and using the flash LED as a flashlight to see where you're going has got nothing to do with the camera app. By modifying the behaviour of the flash LED in the new ROM, HTC have replicated the behaviour of a regular camera and have enhanced the camera app in doing so. Having the flash LED constantly on has got nothing to do with taking better pictures.
When in video mode, of course the LED should be constantly on as its purpose in that mode is that of a video light. This is correct functionality.

I think you're right about this. What would be nice is if there was a way to have a little more control over it. For example - if you're in reaaally low light and want to take a picture you can't even see what it is you're trying to take a picture of unless the flash LED is on - so I understand the op's frustration. What would be ideal is if there was a way to tell the HD2 to activate the LED flash X seconds prior to taking the picture. That way you could make it come on for a second or two before it takes the pic so you can actually see what you're takin a pic of.

or, for those rare times when the light must be on when taking pics, you could always turn on the torch and then start the camera.

Any recommended torch app for HD2?

on my device that results in overexposure

Flash with photosphere?

Would it be possible to make a mod to use flash with the photosphere?
It would help me out alot in certain situations.

I just tried with an app that turns on the flashlight but anytime I went to camera it says it can't connect to the camera. Tried starting up with the camera app then turning on the light but that makes camera/gallery crash.

Hmm, I'm sure someone could dev an app/mod for such use...
Thanks for trying anyway :good:

While flash would be cool, what would be even cooler is a way to lock exposure and white balance from the first frame.

Disable front infrared sensor?

I suspect the infrared sensor in front is sipping some of my battery life. However, I can't seem to turn it off! I turned off all the Smart Stay and Motion and Gestures and Air View crap, but when I use my camera to take a photo of my GS4, I can still see the infrared sensor lighting up.
Any idea how I could turn Infrared off completely?

Have you tried just rebooting the phone?
Sometimes the senson gets stuck on on my Note 2 after a phone call, despite having "quick glance" turned off. Reboot sorts it out.

Messages has nothing to do with Infrared Sensor.
I think you are talking about the Notification LED.

I restarted the phone and still no go... and yes it has nothing to do with the notification LED

Dude I'm telling you its not the led I'm not stupid I know what notification led is. I had same thing on my note2 you can find a thread there. It's an unread message.
Unless you are taking about Hal sensor
