Hi,
A naive question for developers.
Can the LED light on the front be manipulated through an app
to function as a torch?
Regards,
Sam
The LED lights really aren't that bright (compared to the Droid1's or Droid2's "Flash" for the camera).
I think they were working on the LED manipulation, but ran into issues. May be resolved now... "Torch" will probably not be possible (as the LED is just a dim notification light), but possibly...
The only lights that can be used as a "torch" would be an LED flash, as that is the only light that is bright enough, however the Sidekick does not have an LED flash, and therefore does not have any LED to use for this.
Short answer: no.
thanks for this information mate

Hi,
I was wondering if this is normal on my Touch PRO.
When I launch "Camera" app, go to settings and tap "Flash Light", the LED turns on and lights constantly until I tap it again to disable.
Accoring to manual (and common sense) it should allow the LED to make a high powered burst when shooting photo, and not just light constantly (I thought that 'torch' apps are for that).
In few words: My Touch PRO "flash light" LED works like a torch, not like flash.
Do you get this behaviour ?
Is it normal for a LED-enabled camera phone ?
Cheers
dont have a pro yet, but from what Ive read and seen on reviews its supposed to do that. It stays on then flashes when you take a picture. No need for a torch application..
hi
I get the same, when you turn the flash on the light comes on, when you take a pic it flashes gos out for 2-3 sec then turns back on.
This is normal behaviour. It was on my Hermes as well. The LED is enabled, but not at "full" extend. The light is meant so that the camera can focus when you are taking a photo in a dark environment. At the moment you make the actual photo, the LED lights up brighter for a second.
This behavior is necessary for taking pictures. The camera app assumes that if you turn on the flash, the ambient light level is low.
The flash then lights up at a medium level to help you frame the shot on the screen (that would otherwise be too dark or too noisy to see anything).
Finally, once you actually take the picture it flashes at full power to allow for a decent exposure.
I hope it helps.
Does exist any shortcut or program to turn on the flash light without starting up the Camera app for using it as a torch?
at the moment, no.
The usual suspect, VJCandela, doesn't seem to work with the Raphael just yet.
I've been working around the light sensor and with the available reg. hacks on this forum. I could not find anything that could make a difference.
Is it for real this sensor? I tried to focus a strong light towards the sensor and other times remove the light, the dimming and the device light is just the same!
I reckon technecally the light sensor should dim under high light beam and back to normal under dim light surroundings!
Works on mine. You definitly have it turned on in the power settings? I find it works best if you put your finger over sensor in bright light.
Thanks for the tip. But couldn't figure out anything that could've worked! Could you be more specific? BTW the settings under "Power" is all to default.
under Start>settings>system>power>backlight tick the box 'Auto adjust backlight'
LOL........no not nother one, but I had a thought last night.
Whilst using the camera flashlight for something it was just a bit 'in your face' if you know what I mean.
It got me wondering is there any possiblity of using a slider to select the brightness of the camera flash so you could dim it a little (reading a book...etc)?
Or would this have a catastrophic affect on the LED?
there is an app called flashlight that uses the screen not the LED which you could use
using the screen for such a purpose would drain the battery preeetty quick i'm guessing =)
So would the LED so either way its draining the battery
The screen one is great, you can change colors and everything too
Hi,
I've been searching the world, the interwebs and on this forum... but nothing seems to come close to what i actually (need) want for my HTC Hero, Since i find myself blind at night it can be challenging to avoid obstacles at night and i have to either turn on the light or use my phone with a "hey look! my phone is a flashlight / tourch" app that uses my screen by turning it bright white (witch hurts my eyes, wakes my GF and drains my battery).
One night i realized that my indicator led (at that time green) was enough light to successfully navigate the dark bedroom at night, without waking my partner... but allas it only showed up when it was done charging and still plugged into the adapter / computer, unfortunately many a usb cable do not reach beyond 1 meter. and i was again forced to use the "hey look! my phone is a flashlight / tourch" app witch got me into a lot of trouble again...
of course i tried the look my phone is a flashlight white screen apps but they tend drain the battery real quick and anoy my partner.
in short... i'm looking for an flashlight app that uses my indicator led instead of my screen or the non-existent camera flash LED.
can anyone here point me in the right direction or make an app like this one
I would be very grateful
Cheers

I am unsure if you can control a hardware LED. I will look into it.
thx that would be awesome, thanks in advance
So yeah, screen flashlight apps let you control the brightness, and the one I used long ago, also lets you control the size of the area, color, etc....
that might be so but the screen flashlight is imho anoying and i would prefer to use the green LED

I think you can only control it when you are rooted and it is very device dependent how this is done. But yes it can be done... Basically it comes down to finding the right files in the /sys directory that are controlling the led(-s) and output something to it (usually a 1 or 255) to switch it on. (Maybe this is some info that other developers can use).
I have read some of the troubles in Nexus S LED flash. Most of the people returned their phone and got it replaced. For my phone, I cannot do the same. Below are the details of my trouble with the LED flash.
Before, my LED flash works fine but after installing an app from Play store, an app called Tiny Flashlifht + LED by Nikolay Ananiev.
Since then my flash comes and goes. When I use it while taking a pictures, when the camera focuses on the target, the LED lights but then when taking the shot, it doesn't.
Then I tried to install another after deleting the app. An app called Brightest LED Flashlight by Surpax Technology Inc. I tried to use it but my LED only lights up a little. Like a tiny dot of light on its LED bulb. It flickers but not very bright.
So, is this hardware or a software issue. When my LED flashes while taking pictures, it is very bright though.
