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

Hi all,
I tried to put the flash (light) for a picture, and I have an issue... The flash is lightening before taking the picture, so it's useless ...
Do you have the same issue ?
When I turn my flashlight on it stays on until I turn it off.
It stays on, but it's brighter on the moment the picture is done.
I've tried to make photos in front of a mirror to see if it is lightening before taking the picture or not. In my device (HTC TyTN) the flash comes just at the right moment, so it's not useless, but the shooter sound comes about 1 second after the picture is really taken.
Do you have a lot of applications running? probably your device is running slow and that's why you're experiencing this. Are you experiencing the same issue just after a hard reset?
Yes maybe, I'm going to try the mirror test
I have the same problem
The flash light it is NOT syncronized with the capture moment.
I think the question here should be;
When is the capture moment?
Pressing of the button does not coincide with the shutter sound or flash lighting... This is probably as the flash lights when button is pressed, at which point the device starts image transfer and the shutter sounds after picture is complete (try moving camera after shutter has sounded and before)
guys is there no auto flash on the camera? it seems you must manually select to turn the light on or off, this is terrible and time consuming
any fixes? i still think after the k800i, sony's camera went down hill ;(((
This seems to be the case, I haven’t come across any fixes, and hopefully an official firmware update should take care out it, although…. shouldn’t the coders here be able to outcode official Sony programmers lol
Thats how it is with LED "flashes"
A LED cant emit enough light to really work as a flash, so meh
hmm, yes i hope somebody fixes this, one of the reasons i upgraded from diaond was for a flash camera and well its quite frustrating ;((
Frustrating I agree, I upgraded from a nokia N95 with a LED flash and that knew when the light low and turned on..

LED flash is never going to be a flash... even is it's on by default or by light sensor... so deal with it.... I haven't seen any led flash act as a flash..
if you think i'm rude... well.... Maybe I am...
Drunk.....
Well, the point should be that it should still turn ON/OFF automatically, regardless if it flashes just as you push the shutter button, or turns on beforehand when it detects low light.

Indeed. I dont think anyone expects the X1's LED to be truely "flash", but seriously... other phones can detect low light, and turn on when the picture is taken, then turn off after again. No need to "manually" turn on the light when you want to take the photo. It's pretty stupid.
PLUS this phone has a light sensor, AND just using the camera alone it should be able to detect low light. What gives?!
And I thought I was doing something wrong with my settings that caused the phone NOT to flash. Do other phones with an LED not flash? I'm pretty sure my N95 does.
yes this phone is FULLY CAPABLE of this but stupidly it just hasnt been incorporated!
the Raphael/touch pro has the same issue
You can change in the registry so the LED will start automatically when you start the camera. I think it is good. Because when you need it, it will work and when you don't need it it doesn't matter because it doesn't affect anything. Of course you can turn it of in the settings as normal.
set HKLM\software\SonyEricsson\Camera\PROPERTY_PHOTO_LIGHT to 1
Note: Don't know if it is the same on R1 but I'm using R2 with the latest camera software

Interesting tweak!
Not ideal (sometimes you still want it off when in medium light) but certainly better than always off.
I am a bit disappointed that the latest R2 firmware did not include an improvement to the Camera app that would set the light on/off automatically based on the light level. Seriously, is it THAT HARD?
The backlight turns up/down based on the light level... and I know other people have written apps that do things based on how bright it is...
I'm having a problem in the sense that the camera seems to only take octure after the flash turns off. this is when the flash is set to auto mode. as a result my picture looks darker with the flash on then without. anyone with this problem as well or any ideas what to do

I noticed same thing. Looks weird for me too. No idea how to fix it. The problem not always exist - photos are ok when I shot in total darkness with flash. If i take photo with some light then it looks like after flash turns off.
Anyone else noticed that?
No, this is normal. It reduces the exposure time when flash is on, so that pictures do not get overexposed. Every camera does that.
As a result, you may get darker pictures with flash than without, if you use the flash at times where it's not needed. Just turn the flash off then.
I noticed this too, as in the flash fire and the camera shoots but the image from the preview that remains on screen for a sec if for example you press delete, looks better than the actual photo.
It's like the camera needs to capture the image a few milliseconds quicker or something.
No no no. You all got it COMPLETELY wrong. I already gave you the explanation above.
It takes the picture exactly at the same time that the flash turns on. It does NOT shoot too late.
It just reduces the exposure so that the pictures don't get overexposed. ALL cameras do this!
Sometimes, however, it uses the flash when it should not. These are the times when pictures would turn out better with the flash than without because the flash cannot compensate the reduced exposure time. Just turn off the flash and everything is okay.
This happens with every camera that uses auto flash, but it happens particularly often with mobile phones that have an LED flash. This is more or less normal and you can't do anything about it, except for turning the flash off manually.
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.
Noticed that my Note 3 N9005 has weaker flash light compared to my S3, the weak flash gives my pictures in dark a tinged yellow color, is it ia something I do while taking pics make it yellow or is my flash defective??
downloaded 3rd party flashlight app and it did give me a much stronger flashlight than phone's flashlight widget, however; I still don't know how to make flash stronger while taking pictures or videos, any help would be appreciated.

Flash in pictures should be on full power (if needed).
Flashlight apps wont use full power, else you will break you LED.
It doesnt have enough cooling to be turned on on full power.

I think if you want high quality pictures get a high quality camera.
This is still a phone, but should produce nice images tho.
You could try to make a picture and attach it here so we can see what you mean.
But its possible the flash is not working like its supposed to.
Ok will try thanks
