Do these selfie cameras change your face? - Galaxy S6 Q&A, Help & Troubleshooting

Am I losing my mind or do most camera phones do this? When I take a selfie and put my face at the top of the screen it seems to throw my face out of proportion. Makes my head and eyes big and my jaw area look small. When I put myself at the very bottom it makes my jaw area and cheeks seem elongated and bigger.
I think I'm right about this because once I was taking selfies with this girl and i centered my face in the screen. She was a lot shorter than me so her face ended up at the bottom and her face and head looked huge and elongated and she had me take another. This time I centered her face but then mine was at the very top and I looked horrible. The 3rd attempt I just put it in landscape mode and held it far, centered us both and we both looked normal... At least I hope I did.
Im feeling anxiety and depressed about this bcuz I feel like I don't know how I really look.

It's the fisheye effect, common in many very wide angle lenses. The further the subject gets from center, the more distorted it becomes. If you want to see how pronounced it is with any camera, take a picture of graph paper filling the lens.

Rear camera distortion

Just noticed that when things are in the top portion of the picture with the camera tilted down slightly things get distorted. It makes heads oblong and alien looking. Wondering if other people have this same issue or if it's just my phone. So it's really a question of whether the phone is being exchanged or returned.
I've attached two pics. When the tv is in the top portion of the pic it looks a lot taller than when it's in the center of the pic. Both pics were taken from the same distance at the same zoom amount.
Did you take the plastic film off the lens that comes from the factory?

I was gonna say the same! Although mine lately has not been focusing at all unless i shake it. View is immediately blurry, but up close to something it is fine. Like it is stuck in close up. Shake it and seems good. This is before ROOT and playing around. Any ideas?

Did you have a plastic film on your camera? I had one over the fingerprint sensor but if there is one on my camera it's near impossible to detect, I feel like I'm just scratching at the glass although my fingernail is definitely catching on something. I just cant tell if it's the edge of the glass for the camera or a film covering it.
i had the same issue so i boiled my kettle, and held the phone above it after it boiled and let the steam peel the lense sticker.

If you had the plastic on it, you'd know it. It was very noticeable on mine.

I really can't tell if it's there, if it is it lines up almost perfectly. It isn't causing me issues for now though so I'm not going to mess with it.

You would notice in the center of the lens. The plastic would have a cut. Once it's off, the lens is perfectly flat across the top.
The plastic was still on, but no change in distortion taking it off. I'm guessing the cutout in the center of the plastic makes it so it doesn't impact photos.
So I tested on my computer monitor and am able to somewhat replicate what is happening in your shots. However, this distortion is natural because you're tilting the camera downwards on its axis. Its called perspective lens distortion and is common to all cameras without a tilt shift lens (a lens that costs several thousand dollars). You should be able to replicate the effect with any camera phone.
Yeah I've noticed distortion in other cameras but it's just not so extreme. On the s6 the distortion makes any pics with the subject on the edge ridiculous and unusable.
I think I've narrowed it down to when the s6 is set up to shoot max resolution at 16:9. When I switch it to 4:3 the distortion is pretty much gone since that distorted area is just cropped out but that reduces it from 16mp to 12mp. Other phone cameras I've had (moto x 2nd gen and s3) crop the other way (max resolution at 4:3 and then crop to get 16:9).
So the s6 presumably has a 16:9 sensor where the others had 4:3. But the extra width is pretty much unusable.
I'm not sure how I feel about this. What's the point of having a 16mp camera if you can only effectively use 12mp?
Any update on this? I was hoping there's a post processing software in Android/Windows/OSX that can compensate for the lens distortion even though it'll reduced the resolution a bit. I have a AT&T Galaxy S6.
I tried DXO Optics Pro 8, and it works very good for shots from my Nikon D7000 to un-alienize the faces, but there are no modules for the Galaxy S6 lens.

New screen replacement seems to have a cloudy dark spot....

I think there's too much pressure being applied somewhere but I can't seem to find the spot. It's very light and doesn't really show in pictures, but to help give you guys an idea as to where it is, it's about mid to a quarter of the way up from the bottom of the phone. Any tips on how to alleviate this stress area?
Edit: I forgot to mention that touching around the area somewhat distorts the screen (ripple-like effect when you press down hard on an LCD/LED monitor). Even the lightest tap causes this.
Have you tried disassembling and re-assembling the phone? The distortion happens when you touch the front or rear? Does the glass/LCD look perfectly uniform in colour when the screen is off?
Distortion happens when touching the front and I have disassembled it. I'm starting to think it's a manufacturing imperfection. Seller on eBay claims it's OEM but I highly doubt it, considering the tight fit for the sim and back casing. Ah well. I think I'll just chalk this up to buyers remorse and move on.

Rear camera off-center

Probably a silly question. But I want to know whether the lens's position cause any effect on OIS when it's being completely off-centered as signified by the red circle in the image attached.
Thanks
I don't think it is a problem. If there is no black edges on screen when taking pictures, everything is fine.
And to see if OIS is turning on, just shake your phone (with camera off) and you can hear camera moving . Go to the camera app and shake again, you will not hear the camera moving. It means OIS is on.

I didn't mean whether the OIS will work or not, what I meant was whether the off-center will have any effect on OIS's working resulting in a bit more shaky video relatively?
Turn your phone around and it's centered.
Your welcome

I don't think so. I say this based upon my examination of the eight S7's I've possessed so far. Turning any one of them upside down appeared to merely cause an optical illusion. The illusion was that, if the back camera lens seemed off-center when right side up, flipping the device 180 degrees simply made it appear that the relative lens position had changed, often then seeming more centered.
If you look carefully at your S7's back lens (a magnifier helps), you can easily see that the lens itself is considerably recessed beneath the surface. That is, it is set back below the protective surface glass and the surrounding circular port opening. This means that when you look at the lens straight on, a crescent shadow is cast around a portion of the lens. And that makes it only appear to become more centered or more off-centered. The crescent shadow will change position depending upon the direction of your back lighting. You can hold your S7 facing its back panel, look at the lens, and pivot around in a circle to change the direction of the back lighting. You should notice the illusion of the lens moving from one side to the other as the back lighting becomes oblique from the opposite direction. A similar thing will occur when you turn the phone upside down.
Out of the eight S7's I've possessed, only one of them had a near perfectly centered back camera lens. As long as no portion of the lens is overlapped by the circular port opening, there should be no performance loss with the camera function. As stated, an off-centered back camera lens is actually only the position of the internally mounted camera module as relative to the external circular port opening. And the movement illusion is the shadow crescent moving around. The OIS movement should be so minimal that it will be undetectable in terms of how centered the lens appears to be.

Hi there.
I just got my S7 Edge today which seems to have the same misaligned camera and circular cover.
Did you notice any effect this has?

Help.

:crying:
Hello, I've got an issue, that is not SW related, but rather HW related.
Well, here's the story. I went to beach, took a photo, sent it via whatsapp to my friend. Everything was fine.
Then I put my phone in bag. 30 mins later, I took it out and wanted to take a picture. But the picture was blurry, it's like all the time blurry. Tried to reboot, did even a factory reset. The issue still persists. It looks like some dirt got behind my camera lens and that's why it's not focusing anymore on objects that are more than 30cm away.
In this picture(DSC_00002) you can see how the focus works, if the phone is like 30 cm away from the glass.
And this(DSC_00003) is a close up shot, a lot better. You can get clear photos, with excellent detail.
Another detail I can add, that when I try to focus objects that are more far away, the camera somehow focuses on the middle only. Like a circle in the middle, just like a bubble effect. I can't even show how weird it is. 0_o
Updated. I added a picture of the lens. You can see at the bottom on the lens, inside, there's a little white dot right next to the reflection of light. I think that may be the cause? How can something like that get even behind the lens cover?
Anyone could tell me, if my lens are damaged or it could be a tiny piece of dirt behind my camera lens? Because when you look at the lens in sunlight, you can see a little particle over the lens. And that may be the problem, why the focus is broken. I just don't get it... The phone was supposed to be dust proof. And it was supposed to be sealed in all ways. It was once taken to a repair shop, to change the LCD, because it had USB burn marks and so on. And there it might be not sealed tightly enough. But that's the front screen, which got replaced, not the back of my phone. The phone even doesn't qualify for the waterproof test. It just shows that it's not waterproof. Even if I tested the pressure levels in my phone. Should I take it back to repair shop.
Thank you in advance.

[SOLVED] Rear main camera : something weird under glass ?

I was worried about possible dust inside top corner left main camera sensor (as you can see here https://youtu.be/2KfBsb_qEeE)
Seems to be fixed by nice redpoint73 answer, and after checking again, this isn't a piece of dust (maybe part of OIS mecanism).
Thanks again.
I'm a photography enthusiast (DSLRs, and now moved to a full frame mirrorless camera), and what I can tell you is NOT to be concerned about a single speck (or even several) of dust, if that is even what it is. A single speck of dust (or a few) will never show up on photos or video.
Here are a couple interesting articles from a popular website for renting camera lenses (Lensrentals.com):
First article is about the effect of dusk or scratches on a lens. When you look at the example photos taken with a "fairly bad" lens, they do seem pretty soft/blurry. Then you scroll down to see a picture of what the lens actually looks like, and it's pretty funny. I won't give it a away, it's better viewed yourself. But the point is that a lens can be in really rough shape, and still take decent photos. And even the lens in question, they had to try very hard (very specific circumstances) to get the "scratches" to show up in the photos:
https://www.lensrentals.com/blog/2008/10/front-element-scratches/
Another article, they found an entire house fly inside a lens, and it didn't even affect the photos except when stopped down to f13 (which isn't common to stop down that far) and even then, it was just a shadow, barely visible.
https://www.lensrentals.com/blog/2019/04/removing-fly-from-weather-sealed-canon-70-200mm/
Now, this is a big DSLR lens. And something as big as a house fly would have a much larger effect on a tiny phone lens. But the point being, a speck of dust is not even going to be visible under any conditions on your phone's camera.
Another good example, you can actually take photos through a chain link fence; or fabric mesh such as at a baseball field or other sports. If you get the lens up close to the fence or mesh, and take a photo of a subject far away, you will see that the mesh practically disappears. This also works taking photographs through some very dirty or scratched glass, such as exhibits at a zoo. If you can get the lens close up to the glass, even really dirty/scratched glass becomes nearly invisible. Same exact principle for dust on the lens. Since it is so "close" to the lens, it is not going to be visible. And anything on the lens has to get pretty bad, before it has any effect on the pictures. Really dirty/greasy glass on the camera phone's lens does make a difference - but you practically have to have a layer of dirt or grease.
I do have an old HTC One (M8) that has quite a few specks of dust on the inside of the back camera lens. Don't know if dust was getting inside somehow (that seemed to be the case). It looked pretty bad (looking at the lens) after using the phone a couple years - usually carrying it in my pocket. Maybe dozens of specks of dust on the inside of the lens - not just one or a few. But I can still not see any affect on the pictures.
Thanks for your long answer.
I'm not worried about it anymore, thanks to your thoughts, but also after that I'm pratically sure that it's not a small piece of dust.
Thanks again

You're welcome. Although there is a button for that (thanks).
Also, please don't change the thread title like you did to "Solved" and delete the original content. This is really bad forum etiquette. It may be "solved" for you. But others may have a similar question or issue. A thread is never truly "solved" or "closed" (for everyone) in my opinion, as others may have additional information, questions, opinions, etc. And having a descriptive title (and keeping the original post) helps others find the info, know what the thread is about, etc.
If everyone did this, the forum would be full of empty threads, and the whole forum would be useless.
Please change the thread title and top post back to what you originally posted (as best you can remember, doesn't need to be perfect).
^agree, keep original title intact! Cheers
@basongwe I hope you don't mind as suggested by @redpoint73 and @galaxys but I've re-established the title of this thread as it was provided by you the last time.
I've done it too but thanks

Interesting but I clearly had a speck of dirt that showed up in photos on my OP6. I could see it in the lens and was very visible in photos.
