As the title says
I've been playing around with my phone and while trying to cover the lenses one by one and changing camera mode, this is what I found :
The main middle camera Is the 32mp one and I can cover it when taking normal pictures
The zoomed out camera (I don't remember the technical name) is the top one
I then tried the 3d function of Google measure but it still uses the middle one
So any idea about what the bottom camera is for?
Thanks in advance!
Depth sensor, it's used for live view
Sweet! Thanks for the reply and merry Christmas! (if you celebrate it anyway)

This is incorrect.
It is in fact the bottom camera, ie the one directly above the flash, that does the Ultra Wide photography.
The one in the middle is the high resolution, normal camera with 32 MP.
The top camera, ie closest to the edge of the phone, does depth measuring. This has a low resolution but has the same zoom percentage as the high resolution camera. It has 5MP.

I have a problem with my rooted One X that on close up objects the camera can not focus on the subject, this makes barcode scanner apps useless they simply do not work anymore,
Camera shots at normal distance focus properly
Any help?
I get the same problem. The camera gets a sharp picture, then refocuses, gets a sharp pic.. refocuses!
It never sets itself & stays on the sharp picture.. always trys again!
Very frustrating.
try to use digital zoom then pull out

This seems to do something it certainly makes it better , still nit great though
@Op,
This is actualy normal.
Every lens has a minimal distance it still can autofocus.

Not true all my other phones focus much better than this . When I first git phone it worked .even my friends cheap huwaei focuses better on near objects . Something is broken
Not true?
I do have some experience with photography, like I said every lens has a minimal distance for autofocus.
You can read that in every manual of a new lens.
It's called 'min. focus distance'

Sorry i replied on my ohone and autospell failed! The phone USE to focus on the barcodes perfectly fone but now it does not!
My other phones can focus on these barcodes fine but now my ONE X does not
I have noticed, that HOX is almost never focusing on close object (even 20cm from the lens) if there is a distant background. Touch to focus or macro mode doesn't help. Try to make macro shot of the flower while the window view will be your background.

But the barcode apps dont offer the possibility for digital zoom
focus problem
I have the same problem, i used to have a sensation XE just prior to my One X and the short distance focusing was about 7 - 8 cm or even less sometimes. the one x is nowhere near this distance and overall quality (as opposed as to what was advertised) is not extraordinary
i made a topic about this months ago but everyone's against it.
The HOX have much longer min focus distance, i'm disappointed because this has a f2.0 lens but it cant focus as near as my XL with f2.2 lens so the bokeh in macro shot is much much smaller even when compare to the XE f2.8, and alot of image compression which degrade the quality ALOT.
It's not broken, it's just designed that way
Try Camera 360 app. Its free and comes with lots of filters. One thing it does better than stock camera is focusing better on closer objects like the OP mentioned.
Hi, anyone found a solution? Still I can't use barcode scanner (was perfect before android 4.2.2 update I think)...
Hello guys,
Ive been playing with my mi6 for a while and noticed a strange thing. Photos captured at 2x look actually more like a digital zoom than an optical, even though the resolution is the same as 1x. When you actually cover the left camera lens, the picture is still normal. No matter if you choose 1x or 2x.
Any ideas?
Thanks in advance.
You can explicitly set the lens on manual mode.

Thanks, you da real MVP!
Where can you change that? Still on MIUI8.
it does that in low light shots, cause the tele lens is so bad at low light that it prefers to shot in main camera and zoom it in.
sources : miui forum? red it when i bought it

That's right, the telephoto sensor has 1.00µm pixel size at f/2.6 aperture, while the main sensor has 1.25µm pixel size at f/1.8 aperture.
Daisy should have second rear 5MPx camera but I dont think that is even used, it feels like just a hole. Doesnt help for bokeh, in low ligh, for zooming. If I covered it image was the same. Anyone knows when this camera take any effect?
same problem, bad front camera experience

next time please read post before you write some unrelated text
I think so too
It is definitely not fake.
You can test by going to dialer and typing *#*#64663#*#*
In that test mode you can test each camera lens ( finger over lens) and that will verify both cams do in fact "work"
Not saying the software actually uses both, but the cams are in fact real

Im not so sure in my case:laugh::laugh::laugh:
edit:same for dual back camera
With the stock camera app, it does work correctly. Perhaps you should contact warranty...
The portrait mode that focus only on what is close must be a proof that the second camera works, right?
If you cover the second camera in potrait mode in stock cam app, you will see that it is not working properly anymore
the 2nd camera only there to enhance DOF information
not to actually take a picture.
front camera is also able to fake the DOF but its slower and not so accurate when compared to the rear camera

This works for me! Thanks. I don't know why others doubt their smartphones
i also use this model and i think that secondary dual cam is just for show off it does not do any thing. its a mimic only for branding purpose.
So many people have no idea what they bought.
The first sensor is a 12MPx Sony sensor (bottom one) that captures standard photos, in focus.
The second sensor is a 5MPx Samsung sensor (top one) that analyzes the whole frame and returns RAW depth data for the camera app to process, to bring a better blur effect for the portrait mode.
This is a bonus to the classic software portrait mode, it helps. It's not useless, and it's not for show off.
The fact that it doesn't work as good in dark environment is because the Samsung sensor is cheap and can't give enough data in darkness.
Now, let's see when both cameras work at the same time (not applicable on this device):
- when the secondary sensor is black and white, this helps the pictures get more dynamic range
- when the secondary sensor is the same as the other sensor, this is used for 3D imaging (chech HTC 3D)
Now when 2 modules work independently and can be switched via software:
- when the main lens are normal and the other lens are wide lens
- when the main lens are normal and the other lens are zoom lens
Now, our device doesn't fit in either of the above categories and the best way to use the Portrait mode is to use a ToF sensor, but baring in mind the price of our device the ToF sensor was replaced with a standard, low quality camera sensor from Samsung.
Hello,
is also someone else encounterin blurry macro / near range pictures with the main camera?
I have this issue also with the pro mode of the original camera app and in all resolutions of the main camera.
I compared my S22 with an A71 (2020 model) and the A71 makes significantly better makro pictures. (Example pictures attached)
On the left side is the A71. On the right side the S22. Same distance.
It is possible to focus on the blurry areas on the S22 to make the blurry spot sharp. That's why i actually think it's no hardware issue.
The phone is on the current SW. Last update S901BXXU1AVDA from 20th of April 2022.
Thanks

May be the blur map of that particular lense.
I thought so too.
I tried making a picture without moving as good as possible.
On the left i focussed manually the "M" and on the right side i focussed manually the "8".
Might be a bad copy... it happens.
Try using a proper blur chart to standardize the issue.
hello,
I'm having also blury pictures.
I had noticed it as I took pics of printed media. Ofcourse cam was parallel to the objects while taking pics.
Unfortunately it will be a problem of the lens ;(
I actually still hope it's a software problem.
Since i can manually focus the objects.
A friend in the meantime bought a S22+ Exynos model.
Exactly the same issue with close objects blurry zones appear around the center of the focus.

Purely an optical effect. All lens have a blur pattern, this is a $600 macro. It's desirable to have the least blur near the center.
How to measure blur.
If that's the case then the camera of the S22 is cleary worse than my previous phones when it comes to near / macro pictures.
Note9, S10e, S7... I think all made at least better macro pictures with not such wide ranges blurry.
That's btw. the only disappointing thing about the S22. The rest is absolutely fine.

Too close ie out of range, cam shake or inaccurate AF.
Try manual focus...
First: I completely agree with blackhawk.
Second: Please redo the comparison with a flat and perfectly parallel to the phone aligned subject.
Third: It is a bit easier for the A71 to create less blurry makro pictures, because its sensor is a bit smaller.
Forth: The A71 lens has a bit less wide angle. To create the same picture the S22 needs to be placed nearer. This makes it harder for the S22.
First of all thank you for your help and tipps.
I printed such a test paper in the best quality my cheap printer can do.
I made a 50MP picture approximately 10inch away of the paper. A parallel aligned as possible.
I see the same as on other near range pictures. The top area is the most blurry. If i stay in the same position and manual focus the top blurry area then it becomes sharp (that's the reason why i always thought it's a software problem)
Anyway thank you again

The area of of blur means it's not at the same focal plane as center of the lens.
Not that's impossible to focus that area...

If all copies have this same blur pattern, no.
If it's a bad copy, yes by replacing the cam module.
However...
Pan back a few inches, does it still happen?
Are you shooting at or closer than it's minimum range limit?
Look how blurry to the top and to the bottom.
- Tripod
- smartphone plan
- distance 21,5 cm
- zoom 1x
- much light ...

Use a proper blur target...
I know what I'm doing.
no matter what I take photo of every time same results.
proper enough?
some lines aren't clear, but the lines at the very end up are clear (?)
took more shots and every time the same problem ;(

Hi all. I am debating the switch from the regular 6 to the pro.
Looks I will be getting bigger higher refresh screen (pro) which is curved (con) and with worse battery life.
One thing that is not clear to me - is the zoom lens used in any other situations than when actively selecting it? For example - which of the lenses is being used when you select the portrait mode in the camera app? Is it using the telephoto lens to battle the fish eye effect?

I have never gotten the telephoto lens to show up in gcam. Only the 50MP wide cam and the 12MP ultra wide cam. The 50 gives you zoom options but the 48MP telephoto never shows up

It's a 4x telephoto, which is a lot for portraits (so portraits are taken using main camera at 2x magnification).
No, it's not being used for enhancing ultrawide. I suppose it's also because if the same reason mentioned above (OnePlus uses it's 2x tele for this as well).
Telephoto is really only useful for zooming 4x and up all the way to 20x, when photos are still kinda useful (depending on a scenario), thanks to being a 50 MP sensor and some Google's AI magic.
I take a lot of zoomed pictures and I don't mind curved display. Battery is okay, 6 hours of SOT are real for me, usually on social networks and news scrolling. Sometimes I play a League of Legends, than it will drop to 4-5 hours.
Zoom lens is for... zooming in. I would think that would be self-explanatory?
It kicks in when the magnification reaches about 4.5x. Switching between sensors is exclusively a matter of changing the magnification level, not by "selecting" a particular camera. There are other details considered before switching sensors, such as exposure requirements.
You can tell which sensor is in use by briefly blocking sensors with your finger. When you see your finger on the screen, you found the sensor that is in use.
Yeah, thanks
What was not clear to me was if it is being used when shooting portrait photos, as some phones (e.g. Oneplus) do.
Looks like this is not the case.
I will stick with my vanilla 6 then, not missing out on much, subjectively.

Portrait photos can be made with ANY lens, depending on the distance and direction to the subject(s).

Is it so? How does the portrait UI looks on Pixel 6 Pro? On the vanilla pixel I have the options to shoot it in 1x and 2x only. Does the pro version offer a higher magnification, using the zoom lens instead of main one?

No. 1x and 2x are the only options available. The telephoto lens isn't used in portrait mode.
