Hello, has anyone noticed that the led when using as flash light is pretty week? I've had Nexus before this phone and it lighted very strong, sometimes I even used it as light in repairing the cars and this one is useless?

Yeah I've noticed that too

Yes, it is. But for photos it's fine for me.
Yes, it's weaker, because it's primary function is to aid the camera in low light and the Exmor sensor does not need that much light, since the photos are fine with the flash.
The one one the M7 was much brighter, but people always complained about being blinded when taking a photo, so this is actually quite good... unless you use it to repair cars and such
Well much clear now . Not actually repair but sometimes this led was helpful, now I need something else .

Another thing to note is that most flagship phones these days are equipped with DUAL led flash where z3 compact is equipped with one led flash.
That's where the lack of light comes in.
My Nexus is with one light but much brighter. Tried to tweak this one but without luck.

The LED can seem to go much brighter than when in flashlight mode. I've taken photos in the dark and the flash is much brighter than the flashlight. It's almost like flashlight mode is throttling the LED (perhaps due to overheating risk?). Annoying nonetheless. I used my N4's flashlight while walking down dark trails and it was pretty good. The Z3c flashlight is too weak for anything other than close-range lighting.

Same "problem"for me all my phones in the past were very helpfull at work or when walking around in the evening or at night, my xperia's (i have a z3, too) aren't too helpful. never had overheating problems before, and i regularly made use of the flashlight, often more than 5 minutes. now i have to carry an additional flashlight, very disappointing:crying:
Good news is, that the torch can function much brighter than it is currently in flashlight mode.
Unfortunately to change that you must have root and modify some values in system/etc. Looks like Sony choose the safe way for flashlight mode (just as pipspeak wrote), because this way it can be turned on for an eternity without overheating.
By the way it's easy to confirm, just point at a dark area with flashlight on, then try to autofocus in the same spot with the camera, you instantly see the difference.

When taking pictures in a dark environment, the camera flash on my EVO darn near blinds whoever I'm taking pictures of, resulting in a bunch of "I just smelled sh*t" faces. Anybody have any idea on how to maybe dim the flash without turning it off altogether?
I would really like to see an answert to this...and also to an issue with the flash that I have experienced. It seems that, with no consistency or reason that I can discern, the flash goes "blue" and results in a picture with an overall blue tint. Any ideas?
most LED flashes do it, i just deal with it
I think a better idea is to have the flash on at a low level so your subject knows where to look, and then the moment you click the flash goes 100%. My old touch pro did that but I don't know why EVO will not?
The light meter on this phone is slow, and it takes a while for the exposure to adjust to the very bright LED lighting. I Also think the WB is off on a lot of pictures as well. Lets hope HTC and Sprint fixes this because the camera and camcorder could be a LOT better than they are.
it would be nice if we could turn off one of the leds as an option which would help with close nite time pictures
Hi All - had my Note for a couple of weeks now, hardly used the camera but just tried it and there is a pink tint/hue at the centre of the camera view area which shows on taken pics too. Wondering if anyone else is having this issue. I have the international/UK white version of the Note.
Its normal all to do with light note and s2 has issue

Yes Ive seen the problem with the S2, however its really noticeable and it seems that Samsung have not fixed the problem at all. Really quite disappointed with it on such a high end device.
i saw it happen once recently with low light and low screen brightness on one camera app. but didnt happen with other camera apps. dont remember which app though. so try other camera apps to see if it is an app problem. turn up screen brightness and see if issue resolves
this problem is very common (the HTC devices i owned had the same issue) and there is not really a solution to it for now. the reason for this problem is within the optics, it CAN be compensated software-wise, but there is no 100% compensation possible. also this occurs only for specific wavelengths, therefore the light-source is important too!
All due to cheap sensors. The sensor isn't big enough to let sufficient light in so the darkest part (the center) gets the weird pink effect. You won't see too much of this when you're out in a sunny day.
This is just the nature of the game with cellphone sensors.
hmmmm... it seems blue on my phone. not pink at all
mine is green..... :s

mine is a perfect mix of VIBGYOR pattern (white!)
mine is sometimes green.
but its seams to be problem with the AWB (auto white balance) and artificial light sources. If I change my WB to a daylight (or what ever) the pink/green spot is gone. When i switch back to AWB most of the time the pink/green spot is also gone
i would appreciate if you can test this
Hi,
Not sure if its just me, however, I tried taking a few photos in full darkness with flash on or even in low light. I realized that the flash was very dull and did not produce sharp photos as should happen when the flash is on. This phone has dual LED flash and I can still say that my Galaxy S3 with single LED flash had a better performance and produced really good photos with flash on.
The problem I see here is that the flash is kinda yellow in color while S3 had a pure white flash and that too extremely bright, however, with N6P thats not the case. Has anyone else noticed the same and is there a possible fix for the same ?
I agree, it's not that bright...
The flash on the Nexus 4 is also brighter than this one.

Yes, infact all other phones have a white light flash while this one has a yellowish flash. Even if you're using it as a flash light its evident. This is really depressing to see on an overall excellent phone, though my phone too has that ghoulish yellowish tint, but I've learned to live with it.
I agree, the LEDs are not as bright. My Nexus 5 ( 2013 ) has a stronger LED with a cold white tone while the Nexus 6p is not as bright and has indeed a warm-white tint. It´s not a huge problem though since I don´t use my phone as a torch light.
I believe when I first got it I had used it as a flashlight in a dark bedroom. When I was near the wall I could see that the two LEDs looks like they were different colors. One appeared more yellow while the other was more white. I assumed it had to do with balancing out the flash or something. I didn't really pay much attention to it because I take very few photos with flash.
The Nexus 6P (like many newer phones) has a dual LED flash. One LED is a warm white, while the other is cool white. When taking a photo, the two lights are mixed to create a color balance the camera deems appropriate to the scene. When using the flashlight it just turns them both on at a fixed brightness, resulting in a warm-ish colored light.
I really *don't* like this - there should be an option to just have the cool BRIGHT led activate when the tourch function is used
Hi Everyone,
Have a look at attached example image to see what I mean.
Please try to take a manual shot with your wide lens in a very dark environment with very high ISO (3200 in example) and exposure time of 5secs plus (20 secs in example).
Everyone who has tried that so far has the same issue, a big purple shadow on the top. It's most likely the laser and it won't happen with the normal lense.
Do you have the same result? Any suggestions what we can do about it?
Whoa! I haven't seen that in a long time. I think maybe around the time of the Nikon D80. I can't currently try this out personally but by the sounds of it what has happened is called Amp Glow. It's when you kind of start getting out of the bounds of what is really acceptable shooting conditions for a given sensor. In this case, if you really are shooting in conditions that call for high ISO AND still need a shutter speed of 20 seconds and the image still comes out that dark, then you're way beyond realistic expectations for shooting with a cellphone. In the older DSLRs, people would see it when doing star trail photos that were 10 minutes or longer. Frame stacking software became the solution to this problem by taking a lot of shorter photos and stacking them up and pulling through the new dots of light. (And this is still used by a lot of photographers as it also gets rid of other forms of noise.)
So what is happening? ISO is pretty much the gain. It's the amplification being applied to the signal coming off of the sensor. Ideally with ANY camera, you want to stay as close to the base ISO of a given sensor. That's usually the lowest ISO number. (There are some exceptions where some camera manufacturers have done some trickery to get a lower ISO to show up but that was short lived as it didn't really help things.) Unfortunately, image sensors are not hanging in space. They're packed in with a ton of other stuff. Stuff that gets warm. If that stuff is near an edge of the sensor, that heat bleeds into the sensor and then those warmed pixels get amplified by the higher ISO and next thing you know, Amp Glow. Well, that's the simplified version at least.
A cellphone, any cellphone, is not designed for those kinds of shots. If they were, they would have a tripod mount, a much better flash, and a much larger sensor. (Yeah, the flash on your cellphone is not meant to light up stuff much past 5 feet. Even the ones built into a DSLR aren't meant for much past about 15-20 feet.) The reality is that cellphones are designed for handheld shots with decent light. Even the larger sensor used in some cellphones shouldn't be expected to pull any miracles that top end DSLRs are just barely pulling off cleanly. For that shot, you would want to use a dedicated camera locked down on a tripod using base ISO and long exposure at the very least. Although, personally, I'd probably just take a pass on that shot.
someone on reddit has the exam same issue with the wide angle. and someone said it's in the regular too. weird. my s7 never had this purple hue when I did even 30 second exposure at night.

something obstructing the lens maybe, or just camera went bad
Better hope this isn't the same problem the HTC one m7 had with the purple haze. The culprit was a light sensor on the camera would overhear and give a purple haze on the screen in low light. Place the phone face down and with the camera on and see if the purple comes back.

No, it won't happen with the same ISO/Shutter settings I took the previously attached photo. But maybe that's because it's not dark enough. Did the M7 issue only happen in dark enviornment as well?

Thanks a lot for the detailed explanation. My question here would be, why doesn't it happen to other phone-cameras with similar settings?

Yes the m7 only happened in low light / dark environment. Do a Google search for HTC one m7 purple haze. What caused me not to buy another htc phone

Settings aren't the only part of the equation. The other par is the placement of other components within the device. I need to look at the tear downs to see how the various parts are placed next to each other but something is heating up and passing that heat to the sensor. Just off the top of my head there are four parts together; the two camera sensors, the laser focus module, and the flask module. Each one of those on its own will generate heat if used enough.

It's the same issue. I haven't looked at the HTC issue but from your description of it, it's the same. Amp glow is what it is called in digital photography. (OK, silly that I said digital as you don't get amp glow in film.) The glow will show up because there is no other data coming off of the sensor for those pixels and the heat is amplified as "data".

Ok, just watched the JerryRigEverything repair tear down. The flash module sits right next to the wide angle and the laser focus next to the regular sensor. There is no mention as to what is sitting next to the sensors on the main board but I see silver boxes on each side with one having some sort of black and yellow warning sticker. Not sure what they are so I can't rope them in as culprits. So for now, I'd say it's a combo of the four units of the camera assembly.
Were you running the flash or one of the cameras a lot while you were playing around? Shooting a lot of long exposure shots in a row?
I'll get to test out some night shots and video tonight at a lighting ceremony but I'm still not expecting to shoot 3200 for 20 seconds type shots. Again, that's pretty extreme.
I've searched around and there's a short mention here or there, and I'm not sure if I should exchange my new S7 because it's actually quite an annoying problem that I've not noticed on my S6 or Nexus phones before this S7.
When I take a photo with the camera facing a bright light source, eg the sun or a bright light at night, there is a blue spot that appears in the picture. I know it's a limitation of modern smartphone cameras, and it's likely a lens refraction or reflection, but it really does take away from the photo if I'm taking one of a beautiful sunset or even a cityscape at night. LIke I said, it's the first time I've noticed this in any of my cellphone cameras. I've tested similar exposure in my friends' S5 and they have the spot too. Even my backup windows phone has this.
Do ALL cameras have this? Are there any S7 owners here who don't have this problem? If there are S7s without this problem, then I'm ok with exchanging the phone for a new one hoping for one without this. I'ts kinda a buzz kill for me on such a fantastic phone otherwise.

I have the same problem with my phone. When I take a pic of candles, there is also some kind of purple halo around the flame. I read somewhere that it is because of the lack of IR filter on the lens.
I agree with the fact that this is really annoying for a phone of that price
first problem is lense flare, it depends on optics design and is normal!
second issue (purple halo) is ir radiation not properly filtered, due to probably lacking IR filter.
this is an issue long present in mobile cam history, although there are and were mobiles with proper filtering cam modules existing...

Thanks guys, as expected, i figured it is a 'normal' thing, but it still drives me nuts. I'm still hoping to hear from more people, since misery loves company in the event that some actually say they don't have this, i might exchange my phone for another to try my luck.
I thought I was the only one me too
