Active Flash LED without using camera - 8525, TyTN, MDA Vario II, JasJam General

I'm not sure about anyone else but I have many times found myself using my phone's screen as a flash light. The hermes is particularly well suited to this purpose as it has that nice beefy LED on the back for the camera's flash. I was wondering if anyone knew any way to activate the LED in its sustained low intensity mode without using the camera app?

Or SEARCH XDA It is in alot of cooked roms.

VJCandela is really good as a flashlight. You can also map it on hardware button and thus making it available all the time (I mapped it on button 5 long press).

Automatic screen brightness using camera or Light meter

it is possible ?
I'm using the KAISER, when in a building i set the brightness to low becuase it has a very bright screen and it's just a waste of battery
But when i go outside i can't see a thing, need to set it to high again
And then i just forget to set it to low again
is it possible to make it be automatic ?
(bright outside - high brightness, dark outside - low brightness)
Thanks !
p.s.
does the KAISER have a light sensor like the Universal's keyboard light sensor ?
if so, is it possible to use that ?
ah man i hear you. when my sister got her blackberry pearl, and i saw it automatically change brightness, i was jealous. aha. unfortunately, the sensor is hardware thing.
i'm not sure about the kaiser but i know the hermes has a keyboard light sensor, but it's on the keyboard, and only says whether to turn on the keyboard backlight or not. not too useful, i'd think.
Hermes and Kaiser have front cameras...
but camera is a no-no for battery
Even once a minute, or on power-on?
Well, maybe yes.
I nice Solution would be a Button you press it, and the Brightness gets configurated automaticly: perfect for battery because you do this only on need!
And there could be a standart brightness reseted after having standby on
I dont know how to use the Camera in VB.Net someone knows?
I was thinking more in the direction of the front camera and the timer ....but bettery above all .... if it is possible it would be awsome !
the buton pressing idea is (forgive me) pointless ... if i wanted to press a button i might as well press the on screen button i already have ! (spb mobile shell)
thanks for the idea though !
it's great to see so many people taking interest, hope it will stick !
SPB software is my solution. You can map your jog dialer for brightness. I use that for volume, so I use touch screen to slide my brightness.

look at the screenshot or demo. Map the brightness as botton4 is a option because brightness is a program link for you to set what ever button as you wish.
blah, i have an at&t 8525, so i forgot about the front facing camera. my current solution is to set the backlight to reasonable indoor setting, and i have VJLumos mapped to my Button5 press&hold. so whenever i go outside, I run VJLumos, and when I get back inside, I run VJLumos again (which turns it off) and it automatically goes back to the previous backlight setting.

Camera Flash Lite as A flashlite (Without the Camera)

Is there a software for making the flashlite turn on without using the camERA ON.
It is really useful if you dont want the camera to drain the precious battery... especially if you need it for hours...
I dont remember it, but I think I've seen it before somewhere in the net...

Well, when using the camera app, it's not the sensor itself, but the maxed out backlight and the flashlight LED that eat most of the battery. So turning on just the LED won't buy you too much battery life in my opinion. Besides, i don't know if using a wizard as a flashlight "for hours" is a good idea - that thing is a high power LED, and they tend to heat up during prolonged use. Since it doesn't have any heatsink or even a big PCB to help dissipate the heat, it wold probably get damaged after half an hour of using it at max brightness. It would probably last longer at lower brightness - like when the camera app is turned on (the camera app enables full brightness only for a second when taking a picture), but using it for long periods of time even in that mode isn't a very good idea.
I think you'll be better off buying one of those small keychain LED flashlights, of a bit bigger flashlight using a 1W power LED if you need something brighter. It will be much cheaper than replacing a burned down LED in the phone.
And for short term emergency use - starting the camera app isn't that much of a problem after all.
Using your flash as a flashlight is a surefire way to burn it out. It's a high output LED, and isn't made to be run constantly. You can definitely do this trick, Vijay555 has created a widget that lets you toggle it on and off, but even he warns you of the consequences.

But it's not possible to dim it with this app, the camera program dimms the LED until you actually make a picture.

Actually the flash led is bright but the backlight maxed out with a white screen puts out more light. It still runs down the battery quickly but you are not pushing anything the phone isn't designed to do. I created a mortscript that combines two apps I found on these forums. One maxes out the backlight and the other displays a solid white screen. You can pick other colors too. here is the link http://forum.xda-developers.com/show...4&postcount=24 I use it all the time when I'm under a desk plugging cables into a computer and need a light.

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?

Camera led flash light app?

Hi has anyone found a app that is.compatible with the galaxy tab led.flash light?
I have tried the following but no success so far.
Mobile light
Switch widget pro light widget toggle
Simple light (which claims to be compatible.with galaxy tab)
Led light
A few others that I have since removed.

Use tiny flashlight + led, in the app itself(not working in widget), once the light is on, press on the onscreen button again while the light is still on to keep it on, press that button again to off it.
Meaning, press once to turn it on, press it again while the light is on to keep it on, press 3rd time to turn it off. It's obviously a bug, but great workaround for our overprotective tab
WARNING: Extensive use might damage the hardware as it does create heat.
Thanks,
it doesn't seem to work but i have a suspicion that it may be to do with the Kernel that i am currently on ([OC1.2&1.4GHz][KernelPatch])
might jump back over to modaco's and see what results i get
Yeah I once used LED Light by picolyl , its in market . It worked nice on my JMEv2

Cheers, ive got both the Flash Light apps now and i have just installed the modaco Kernel to see if it resolves my light light issue.
Seems to be working "better" (i.e. the flash light does come on now) but my light goes on and off while using these programs
I wonder if its an issue compatibility issue then. as i am also running overcome rom 1.1.3 + modaco kernel similar to your setup.

Do as I said previously, and u will have light keeps on instead of couple sec off, remember, when the light is on, press the button again!! Not working in widget mode, please follow instructions to the word before saying it's not working.
Have a look at 'Flashlight' in the market too. Does the LED light, but also has some fun options for the screen. Red/blue flashing lights, Amber warning lights, etc. Works fine on my Tab.

just for the sake of warning tho, 1 thing I noticed is that the light density is a bit different from still photo flash vs video light
