So the phone has 2 front facing cameras. The 24 megapixel camera is working fine. But is the 2 megapixel one working for you? I tried covering the camera and there is no difference in portrait blur. It looks like it's just some software blur instead of a real one.
The secound one i used for the bokeh effect.
I know. I have enabled bokeh and covered the second camera but the background is still blurred. Also it does a really bad job identifying what's in the background and what's in the front.
Try with covered lens on Aperture mode. You will see the difference.

My bad. Didn't read "front camera"... Yep on front one no difference if you cover the second sensor.

Thanks for your answer. Do you know any way to check whether it is real or not?
That's very interesting.. i tried every mode, that i could, but as i can see, i don't really know, how to test it out :/
I just got a Mate 20 Lite. Funny if it is a fake camera.
Both secondary "cameras" are "depth sensors".
Anybody with Pie who got the depth sensor working?
Second cameras are working but they are working in conjunction with software. Software utilizes the additional information that is collected from the depth cameras but it does not solely rely on that information. And if you cover it you may not be able to see any difference because thanks to machine learning the software is really good at identifying subjects from the background. There is never a real bokeh on these smartphones because of the tiny lenses and sensors that are being used in them. So you are always in need of some software trickery to achieve good blurr. Another option is to get really close to your subjects but in many cases that is not useful.
Both the secondary cameras, front or rear, are real. But they are only used to the boken effect most of the time.
They are used to capture the depth of a cenary, imrpoving the effect in the final version.
You probably wont notice a difference if cover the secondary sensor, but in some cases can have impact.
Most of the work isn't done by that sensor, but by the câmera software, thats why you don't see any real difference in the images.
That secondary câmera can also be used to improve the quality of some photos, for instance, in the night.
So, is a real câmera? Yes, it is.
But like in any other dual câmera smartphone, is used for some situations, not all the time.

Hello!
The LG G2 has an exceptional camera, we all know that. So to take even more advantage of this I've made a makro lens that you can 3D print yourself. I just wanted to share this with you guys, I hope you like it. More sample pictures and files can be found on thingiverse
Because of me being a new user I can't post the link to it, but go on Thingiverse and search for samsve (LG G2 Makro lens)
Best Regards
Sammy
Here is the link

I wish I had access to a 3D printer though
Thank you!
To be clear on one point, the case is 3D printed, but the lens is from a "copier laser assembly" but you can find these types of lenses in every laser printer!
Very useful
Great man I could use this for an image proyect right now, massive thanks

i guess you've messed up the terms...
1st lens you are mentioning in your post is called "zoom" or "tele" lens
2nd one is called "macro" or "close up" lens (not micro)
Any tips where to get nice macro (or micro, whatever) lens? I was using some lens from cheaps ebay lasers along with my old compact camera, the zoom was really huge but on the other side the quality was really poor. I've also got there some camera lens from Smena 8M and Zorki 4 (Industar 50 lens) but since I don't want to destroy them, I can't really use them for macro (or micro, whatever) (even when reverse mounted, not that much zoom).

most of the macro add-on lenses (or any add-on lenses) you can find for mobile phones are basically the same, cheap ones - good for fun, but no good for anything serious...
only thing that comes in mind is that sony standalone lens that can be used on any mobile device
like this one
http://www.wired.com/2014/09/sony-ilce-qx1/
but for that price (or if you add some extra $), you can find a better compact camera (like one from the Sony NEX series or Olympus Pen series)

Oh thanks for correcting me though. Btw, is this lens for zooming or macro? I really wanted, well at least 50x optical zooming capabilities for my project. Not really interested for close-up shot since i've made my own by just using cd-rom lens. Its not perfect but, well it does the job.

lol... you will hardly find 50x optical zoom lenses even for dslr cameras
if you need that much optical zoom - you better forget about mobile device for doing that...
you'd be better with the FinePix SL1000, Sony HX400V, Olympus SP-100, Canon PowerShot SX50 HS or several other compact cameras which will give you 50x optical zoom and way better pictures than any mobile device for sure...
ps:
you can also search for a cheaper dlsr that you can attach to a telescope with a proper adapter... i believe there are some budget solutions for this combo

believe me - macro lens on phones are PITA to use... especially if you don't have a dedicated photo capture button on your device (and G2 doesn't have it - at least not on the bezel side instead of the buttons on behind of the case)
you can grab a macro lens from ebay for as much as 10$ or less...
downsides are:
- very hard to focus due to being unable to keep the device steady that close to the subject (and you have to be very, very close to the subject to get it in focus)
- on G2 - the macro lens always has a black circle vignette around the image (lens hardly covers the whole frame without the vignette "effect")
- not so sharp images as the real macro photos
- a bit clunky to use because it clips on the device (instead of screwing to the case like i.e. on iPhones)
good points:
- nice for fun (especially if you don't have a normal camera - dslr or compact)
- gives almost a natural bokeh to the macro image (which isn't possible with phone lenses)
my 2 cents

This one problem could actually be resolved by using voice-activated command on G2 stock camera app. It is called cheese shutter and this function is pretty great though.

Yes without a tripod the image would susceptible to blurring. Unless it can take picture at 1/1000s at lowest ISO possible without darkening the picture, yes you wont get professional-quality close-up shot.

Those picture actually very nice. But the problem i spotted is there isnt enough lights. I used to take pictures like those but end up having to bring the camera too close to the object thus blocking lights to shine the object. That is the only problem for this method. At least for me, it is.
Hello guys, I'm really disappointed and I need your explanations please !
I bought my Galaxy Note 9 (960F variant) from an official Samsung store so I'm sure I'm having a genuine one
As you know, there are two cameras in the rear. I thought that the main one is in the middle, and the 2X optical zoom powered is the one at the left.
Well, yesterday I was playing with my phone, and I masked the camera on the left with a paper. So I thought that I can take pictures in normal mode with the camera on the middle, but the 2X option should give me a blank picture only because of the mask. But no ! Both modes (1x and 2x) are using the same middle camera !
It's normal ?! So what is the purpose of the left sided camera ? Is the 2X really an optical zoom or just a software one ?!
Please do the test and answer me !
Maybe this explains is it
https://www.trustedreviews.com/reviews/samsung-galaxy-note-9-camera
My side camera works only on live focus. Everything else I tested works on the center only. I have a snapdragon, the same setup as my wife's Note 8 too. It's the way they are designed.

It's the same thing with the Note8. It all depends on the lighting and if anything blocking the other camera. It works by design. So when you hit 2x it seems it's blocked and gives you 2x digital zoom instead.
So it's truly an optical zoom ? I ask because if it's "just" a software one, I won't never use it to preserve picture quality !

yep, AFAIK, it is true optical zoom. The camera just changes back to main camera if something is blocking the secondary one.

It depends on the lighting
Try and go outside, on a sunny and bright day, point at the clouds or something, and zoom
Then cover the center camera, it should be using the 2x lens (can confirm with my SM-N960F)

You didn't, it's working properly. You are just confused. Cover the middle one and see. Take multiple pics @ 1x and then at @ 2x on both cameras with and without covering. Covering the camera just out it into a different mode so as to not take bad pics by default. The difference is clear of you understand the 2 technologies and have any eye for photography. It's working completely correctly and very nicely.
Yeah like the others stated, it's not supposed to work completely independently and take pictures even with no light to the sensor, it's supposed to be smarter than that, if it's working correctly.

Hey all, I worked this out.
In a low light situation the wide camera is used for the 2X zoom (So technically Digital zoom)
In a situation with more light, it switches to the dedicated 2X camera.
You can test this by putting your finger over the camera and showing it a bight light, then dark. I'm guessing this is because the main (Wide) camera is better at low light.

Yes, although you mean digital zoom for low light situations.
My issue is that sometimes the camera still decides to use digital zoom in good lighting instead of the second camera because it decides that a slightly overcast day or sunset is "low light" or the subject is too close. I'm guessing the second camera can't focus as closely and its optics aren't quite as good as the main camera. In more inconsistent conditions I can sometimes see the viewfinder image jump between the two lenses and usually settle for the digital zoom. Doesn't seem to be used at all in Pro Mode. (I also wish Pro Mode had burst capture)
If you look at the EXIF data you can see which lens is used for your photo. The wide lens is 4.3mm and the telephoto lens is 6mm. The mushroom images were taken 20 seconds apart with "2X" in Auto mode; in the second shot the camera decided to use the wide lens with crop, and the EXIF shows 4.3mm compared to the first image. The crop version just looks like an upscale and has more aggressive nose reduction and edge enhancement; it's not too bad compared to some phone cameras which add too much sharpening or use a simpler interpolation filter. The third image of the grasshopper/locust was in very bright daylight, but the camera decided to use the main camera with 2X crop.
https://imgur.com/a/MYpRogb
With video it tends to be even more obvious which camera is used because if you take 4K in low light with 2X enabled it looks more noise-reduced and interpolated.
I get that Samsung tried to make its camera app "smart" but the 2x button implies that it's using the 2x lens and doing otherwise is deceiving.
If I knew that a zoomed photo would use digital zoom then I'd rather take the full shot and crop later so that I can have more flexibility in framing.
While this is unlikely to ever happen, here's how I feel this should be fixed:
1) Add an option to force switch cameras in all conditions (perhaps in pro mode only?)
2) Hide the 2x button unless the telephoto camera will actually be used. Still allow pinch to digital zoom.
I've looked around but couldn't find any 3rd party camera apps which are able to use the zoom lens. Does anyone know of one?
I've tried a few shot it seems if the lighting isn't good enough it will stick with the primary camera., in good lighting it does work though.
Just do two shots with each and compare the level of detail, it should be obvious.
Has Anyone else noticed that the front camera is capable of taking much wider picture? ?? if you switch mode from SELFIE to Wide Selfie, you'll notice that the camera is capable of taking much wider angle picture. wonder why sammy didn't use this? regular SELFIE seems to crop significant amount of picture..
The front facing camera is usually used for taking photos of your face, this is why, by default it is set to normal mode, not wide.

Yeah that's been advertised since about two notes ago.
But you have to pan back and forth in wide selfie. Like a panorama.
i understand you have to pan it back and forth, but even not panning it's still covers wider angle than just regular "selfie". it would be nice to be able to capture wider on front camera. which is what Pixel 3 is doing.

I compared and saw no difference in coverage area if I didnt pan.
Ok, so I really want to love this phone but I can't figure out why the front camera wide angle photos look sharp (almost too sharp) and the normal 8 Mp photos from the front camera have no detail whatsoever. Look at the attached picture and compare the clarity of the nose, eyes, and eyebrows. The difference is huge. When taking portraits, you don't have an option to take wide angle photos, so portraits from the 8Mp camera don't look good. Normal camera should be the same as the one in G7, but it's not nearly as good.
No effects / skin smoothing etc is applied, so I'm thinking mine is defective. Can you guys take some side by side normal and wide angle photos with the front camera to compare?
Thanks.

Your “standard” camera looks unfocused, which is why it is blurrier.
That said, after some testing I do think the “wide” selfie camera looks better in general. The main thing that bothers me is the two cameras have differing color profiles. I prefer the default color profile of the wide, so that looks better to be.
The same problem applies to the rear camera as well.

It doesn't seem to focus. When I tap on the screen, all it does is change the exposure / brightness, but there is no change in focusing. It seems that both front cameras have a fixed focus because neither adjust to tapping, but wide angle has a good bit more detail.
I stopped by the store and took two pictures side by side - store unit was noticeably better, though as good as I would've liked. I'm getting another G7 for my wife and will have to compare them.

From what I can tell, and based on some reviews I've watched, front cameras have fixed focus... maybe, due to this, the main lens has a larger minimum distance that needs to be maintained for a clearer shot. It still seems a bit off.. but I've been able to get somewhat better shots out of it holding the camera a bit farther away. I'm getting a G7 for my wife, so I'll be able to do some comparisons.

Interesting to note that the 16mp rear wide angle cameras have a different focal length between V40 and G7 - 2.18mm vs. 2.38mm. Both are f/1.9.

Do you find any difference in picture quality from both of these phones (the identical sensors)?

Not sure about the focal length differences...but they're definitely not the same.
When taking a close-up selfie, the main camera on the G7 is much clearer than the V40's. But V40's wide angle is sharper than the main camera, and despite lower resolution, is much closer in clarity to the G7 only front camera. At a distance, the difference is a bit harder to notice.
That said, I did compare my phone to another V40 in the store, and the store demo was clearer, so I think mine might just be defective. I'm just not sure if it's worth trying to replace, since I would likely have to pay restocking and I don't want a refurbished unit from LG.

I guess everybody noticed already that you cannot use the telephoto lens whenever you please, since it's only used on good lighting situations, and cannot be used in pro mode. The reason why must be because this camera is terrible at low light, likely because of the 0.9 nm pixel pits on the sensor. I will attach a photo taken with the telephoto lens, and a cropped one of the same scene taken with the main camera, so you can see my point.
