Camera Light

Is there a way/software that will turn on the camera light of the wizard?
It is handy in dark areas to be able to say press and hold the camera button and have the light go on...

...it will drain your batteries and decreases the lifetime of the 'lightbulb' enormously. Try attached plamp instead...

nah, the "flash" is a suface mount LED. LED's have a very long lifespan... it will long out-live the phones operating life.
Handy program, thanks!

...stupid of me, i never looked for it:
in my screen i've got 3 icons to the right: a lightning strike (i thought for autoflashing), working set and folder my pictures.
If you tap lightning strike lightning led stays on...
See, ...still learning by helping eachother...

yeah but then how do you get it to flash right before it takes the picture like all cameras with a flash do? because with the lightning bolt with a line through it doesn't have a flash...

...probably i've got a flash problem. Mine doesn't flash. I only can activate the light. I never noticed this because normally i use a digital camera (4Mpix) for pictures.

I don't believe it is a flash. It is only a light.

well it is the same as a flash, but it just stays on... i guess it is to help the camera so it doesn't have to adjust so much in a little bit. But it is kinda annoying trying to take a picture of youself with the light on.

The LED for the Wizard doesn't flash, it merely stays on.

well... technically it DOES flash...
It stays on to light the area, then when you actually take the picture it gets super bright (flashes) to light up the area for the picture.

Agreed, once the light is on (no slash on the lightning) it will flash (get brighter, not like a real flash but brighter than before) when u take a picture.
A program would be useful anyway to voice-command launch this feature...
Any Ideas?? (VJCandela does not seem to work on wizard T-mo 2.26 ROM)

So....Any programmer willing to help????

Auto flash on camera???

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...

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?

[Q] Using Heart rate monitor red LED as a notification light? Is it possible?

Hey guys ,
I was thinking about this today. Can the Heart Rate Monitor's Red LED be used as a notification light? And customize the way it flashes to tell you vaguely what the notification is about before you check your phone? I sometimes leave my phone upside down; Even the dedicated LED on the front isn't bright enough to see if there is any notification.
Anyways let me know,
Thanks

I want that too
I was wondering about the same thing
good to see other users on the same boat with me
I want it to be turned on in-call and as a notification LED
is that possible ? anyone ?

I thought a lot more people would be interested in this. Having notification LEDs on both sides of the phone and having the back LED really bright red.

Any update on this?

or at least a way to make the standard LED notification way brighter...my note 2 have a bigger and brighter LED than the Note 4, I hope someone can find a way to make this happen...

Same thing I asked and in hopes of an asnwer

i know that Emotion kernel has a few settings to send more voltage to the notification led, and to make it pulse instead of blink.
and it's also easy to make a profile in tasker to make the camera flashlight flash or pulse when you get a call or whatsapp message or whatever you want
you'd have to be pretty deep asleep or almost blind to miss that then :laugh:
i don't think it's possible to use the heart rate sensor for notifications though, since it's a sensor and not a light
hope it helps a bit :good:

I did use the camera flash as a notification LED for calls. But I don't like it as it is too much like a flash (duh) For example my buddy was sitting in the train in NY and had his phone in his hand and when he got a call, the flash came on and there was a girl sitting in a short skirt across from him who thought he was taking upskirt pics, lol.
And having a red LED on the back is something different and a little better than a white bright flash.
I don't know much about phone coding, but would there be a way to trigger the sensor into thinking that it is taking a measurement, when you receive a notification?

it's probably possible if you can find the hardware path for the sensor, then you could use it with a tasker profile or make it in a mod.
But i have no idea how to find that path, and IF it even works then

Well I know for a fact that CM does have support for the sensor, and its not a hardware coded sensor as it can be used through the S Health app on the PLAY Store. So if you really wanted to know where to start looking I would say start there.
You could decompile the S Health app and see what portions of the system it access's to use the sensor and then develop from there.

I think it's rather hard, not to say impossible if you're not working for Samsung

Up :3
In test menu *#0*# / sensor / heart sensor / the red light can flash without the finger..

any updates on this?

Yes, here too. The Nokia 6 have 2 LEDs (yellow and white) you need to turn on Neon-light Mode for better Pics. Try it.

How to turn on the neon-light mode??

There is nothing like neon light mode option in camera settings

Please use google camera it will always use both flashes (white and yellow ) + it produces much better photo overall, while the stock camera flash use stupid technique where if more blue light is in the frame shot it will use yellow flash only but it's highly inaccurate .
here the link for the Gcam https://www.androidfilehost.com/?fid=745849072291676705 also keep following this thread for update versions https://forum.xda-developers.com/showpost.php?p=73955268&postcount=342 keep in mind to configure the setting as follow https://imgur.com/y3pCF8i or you can play with settings to find the best settings for our likes
