yeah I don`t have the the led flicker problem, my doesnt like the app acts buggy
describe buggy
I also see this. One looks more yellow than the other aswell. I think there are two different flash settings, and the apps try to use the same setting for both, which is underpowering the brighter of the two leds. Mine after about 30 seconds of constant on will flicker on and off randomly.
Have you tried this app

below is the link to the flashlight app I use. It lets you use the LED and/or the screen and works well for me. If you haven't tried it see if that works for you, when I use it I have no issues with both LED's working at the same brightness level.

Droidlight
I installed Droidlight on two different Atrixes. On both, the light color is surprisingly yellow. One keeps the light steady, the other phone has one led that flashes. Weird.
Also seem to have a problem with the led flash for photos. The flash seems dim and photos are underexposed. Not sure if this is just the Atrix, or somehow conflicting with Droidlight (although seems a stretch).
The flashes are meant to work together so that pictures cone out better thaan with a standard single flash. That's why there are two.
When you guys use the apps to keep them on, it causes them to work improperly. Best thing to do is to allow them to work right and download a new photo program instead.

flash issues as well
no matter what flashlight app i use, even turning on the flash in the native camcorder app the following happens:
led's light up bright
led on the left (looking directly at the back of the phone) flickers then turns off.
led on the right begins to blink after about 10-15 seconds!
This is so frustrating and am beginning to believe it is a hardware issue. Anyone else have a similar issue?
Droidlight has a new update solely for "atrix bug fixes" does that solve your problems?

same thing with droidlight
I have exact same problem. What i believe it to be is that the second flash is a red-eye reducer. When you take a pic with flash red eye occurs. The second flash is meant to briefly light up, significantly reducing red eye.
Since the second flash is intended to only briefly light up during a flash picture (the only intended use) on of the bulbs will fire for a much shorter time length.
When you see one flickering, it is just trying to repeatedly "flash" as it would during a picture.
If you are able to keep both lights on through a flashlight app, you'e very lucky, but your light is probably broken.
CONFIRMED
Photography techniques for prevention and removal of red-eye
The red-eye effect can be prevented in a number of ways.
Using bounce flash in which the flash head is aimed at a nearby pale colored surface such as a ceiling or wall or at a specialist photographic reflector. This both changes the direction of the flash and ensures that only diffused flash light enters the eye.
Placing the flash away from the camera's optical axis ensures that the light from the flash hits the eye at an oblique angle. The light enters the eye in a direction away from the optical axis of the camera and is refocused by the eye lens back along the same axis. Because of this the retina will not be visible to the camera and the eyes will appear natural.
Taking pictures without flash by increasing the ambient lighting, opening the lens aperture, using a faster film or detector, or reducing the shutter speed.
using the red-eye reduction capabilities built into many modern cameras. These precede the main flash with a series of short, low-power flashes, or a continuous piercing bright light triggering the iris to contract. (This should not be confused with the autofocus assist beam, which uses a series of flashes for focus instead.)
Having the subject look away from the camera lens.
Increase the lighting in the room so that the subject's pupils are more constricted.
Some computer digital image editors have the ability to lessen the red eye by desaturating the red color.
If direct flash must be used, a good rule of thumb is to separate the flash from the lens by 1/20 of the distance of the camera to the subject. For example, if the subject is 2 metres (6 feet) away, the flash head should be at least 10 cm (4 inches) away from the lens.
Professional photographers prefer to use ambient light or indirect flash as the red-eye reduction system does not always prevent red eyes, for example if people look away during the pre-flash. In addition, people do not look natural with small pupils, and direct lighting from close to the camera lens is considered to produce unflattering photographs.
Various graphics editing software packages have functions to remove red eyes from digital photographs. Some have automated this process, and can apply it to many photos at once. Red-eye removal is also built into many popular consumer programs, such as Adobe Photoshop, Apple iPhoto, Corel Photo-Paint, GIMP, Google Picasa, and Microsoft Windows Live Photo Gallery.

I confirmed that it is in a fact a hardware issue with my atrix. We now have three at the workplace and mine is the only one with the issue. I am getting it replaced.

Thanks. Just noticed this on my Atrix as well tonight. Will be going to AT&T and getting a new one tomorrow.
For anyone else who might want to test their flash:
My problem started when I would use the flashlight app.
-The left LED would flicker and go off.
-Now it doesn't turn on at all.
-The camera no longer flashes the left LED.
I have brightest flashlight free app installed and haven't had any problems. Both led's come on really bright and stay on

I would like to update my issue with the flashlight app & LED lights on the Atrix.
I previously had a phone that started flashing the left LED whenever I used a flashlight app. After a coulpe of weeks, I noticed that the LED would not turn on at all during both camera and flashlight app uses.
I went back to Costco and exchanged for a new unit.
I came to find out that my left LED still blinks after 15-20 seconds of use. One thing I noticed is that the LED on my new Atrix is way LESS yellow than my first Atrix. (Quality control, anyone?)
People have confirmed that their Atrix has no flashing of the LEDs when using a flashlight app.
I am most likely going back AGAIN and getting a new Atrix again.
ALSO, the flashing of the LED is NOT intended for Red Eye Reduction, as someone previously pointed out. That is WRONG information. I believe it to be a hardware/software problem with some Atrix units.
Regardless of the flashlight app you use, can you keep the LEDs both at 100% for longer than 20 seconds without any blinking?
Any input is appreciated. Thanks!
Hey guys, I haven't seen this question asked outside of the CM7 Thread.
I have UnNamed 1.1.0 Which to my knowledge is identical to stock when it comes to the camera aspect.
When I'm taking a picture it will look great on screen but when I go review it in the gallery it looks almost twice as dark. Almost like the shutterspeed is too quick and wont let enough light in. Outdoors the problem isnt too persistent. Just indoors. I'm going to try another gallery app and see if that help but doubt it will. Anybody else notice this?
I was actually playing with the camera last night and noticed this.
Tried adjusting the ISO and exposure and it helped a little. I noticed that after viewing the picture though, it still turns out a few shades darker than it does in the live view. Not sure what thats about.
I'm seeing this issue as well. Any resolution?
I noticed this too, not only that but there is a slight delay from when you hit the shutter.
Seems like any movement screws up the picture as well.
I think the brightness discrepancy has to do with the screen brightness settings.... try setting your brightness way up, then take a photo and see if your exposure "gets darker".... it should be the same as how it looked when you took the photo...
I think when you take a photo, the camera app automatically brightens the screen to the Max... then when you go to review the photo, your screen brightness settings take over... since most of us use the phone NOT at the highest setting, it makes the exposure look dark....
The same theory goes for anyone editing photos... I always brighten my screen when I edit the photos...that way I'm not adjusting a photos exposure if it doesn't really need it... this needs more practice though as I don't edit often and could be wrong ...
If you're having lag in the shot... try turning off the anti shake option... you might think anti shake can ONLY be good but I find that my photos are fine without it.... but I also know to not try to take photos in dungeons...
Thanks ill try it

I have an Alcatel One Touch Fierce and recently my back camera has been acting wierd, whenever I take a video if its a bit dark the video itself will get darker. if I'm outside its fine but in dim rooms its like the exposure sets itself to -100 and contrast to dark. If I move it to the window the video gets fixed and normal lighting. This only happens while recording, and when you save the video itself it saves the parts where it gets dark or back to normal when moved somewhere more bright. This started happening a month after I got the phone any ideas??? THANKS IN ADVANCE!
Yesterday night I noticed that black pixels do not switch off completely on my phone. (as they should on AMOLED, right?)
Try it this way:
Set your screen brightness to almost a very low value.
Now look at a picture which has a black background and very little color in the middle etc. The room has to be dark, otherwise you wont see a difference. (You can also cover your had with a blanked etc., just wait a moment, so your eyes get used to the dark environment).
Hide the statusbar, navbar etc., so only your picture is shown (Tap on the picture once in Google Photos).
When you disable your lockscreen and switch the display on and off a few times you'll see that the picture vanishes first and than the display goes completely dark. It looks like a very light yellow back-light.
Another way:
Again in dark environment power off your phone. Switch it back on and watch the bootlogo. The surroundings (everything that's black) is truly black and "switched off" and than some secs before completing boot the "back-light" switches on.
I tried to find a solution for that. The only thing I found is a setting in Kernel Adiutor named "Minimum RGB value" under the screen section which is set to 35. However lowering it to 0 does not work, the value get reset to 35 every time (Higher value does not change anything either tho).
I'm running Oxygen OS 2.2.0 with bluespark kernel + root + xposed (Gravitybox + XInternalSD)
maybe the black is not that black?
edit: just tested with fullhd resolution black picture and red dot pixel in centre(PNG file, not jpg nor bmp) and everything is working as intended - black is pitchblack(same as when u just block/shutdown ur phone)
edit2: i'm not having my reflex by my side this couple of months, but you can check it making a photo in light isolated room with low shutter speed(20sec should be enough, if they really produce light)

Thank you for testing. I reproduced your result with a #000000 PNG and everything seems fine, as long as the brightness does not go below a certain value. Turning auto brightness off and sliding the brightness completely down enables some kind of light in the whole panel.
Could it be some android feature, which put's a light overlay over the the screen image to protect the eyes in low light environments, like these warm filter mods?
Hello,
Its 1st time to post here however I hope you guys answer me
Recently I bought my mate 20 pro... I noticed a weird glitch in my front facing camera
When I am in totally dark room and use my screen brightness as source of light to lighten up my face the camera goes crazy... It keeps turn red and blue
This only happen in this condition... If I turned on flash while taking the Pic it takes normal photo.. Otherwise I took a Pic when flash is off it goes that blue and red...
Can anyone confirm that it happens to him too?
I tried the following :
1- reseting camera app and nothing happened
2- using facrbook/whatsapp/insta camera app and it has the same issue
This how it turns to blue and red... Not in the same time but color after color
