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.
I've noticed some people have encountered this problem. Simply put, the camera can't focus properly at objects situated at about 2-3meters or further. Autofocus can succesfully occur only at macro shots. Sometimes this is coupled with that infamous camera scratching sound, the one that sounds like a dying penguin or whatever.
Well, my phone does all of this and since it's a second hand unit without any warrany, why the hell not, let's fix it. A new sensor is expensive so i had to find other ways to fix the one i have.
After some investigation is seems that the internal construction of these sensors includes a mobile assembly containing the OIS and autofocus mechanical and optical modules. When you focus - relative to the sensor underneath, the lens have about 1.5-2mm travel space, again, relative to the sensor (that's fixed in the frame). When you focus the camera to an object far away, the lens assembly must travel inwards, closer to the sensor. Viceversa, when you focus for a macro shot, the lens travel further appart from the sensor. Pretty simple.
However, all but one of the lens are made from polycarbonate (plastic) like most of the sensor module's guts. This is not a bad thing actually. The choice was made because the optical assembly must be as light as possible and glass+metal would have weighted a lot more. But using plastic has some other problems.
When i disassembled the phone, i extracted the sensor module and activated it outside of the phone casing to make some tests. What i first noticed is that as soon as i enable the camera app, the sensor will get hot. Real hot. You can't touch it after some 2-3 minutes of it running. Most of the heat is generated by the photo sensor itself. It's how these things work. However the heat output from such a huge sensor is more disturbing then the situations found with other phone's small camera sensors. Even so, for example, it is known that HTC One M7 had a failure mode involving it's camera, due to the high heat output, the sensor would burn itself resulting in a pink/purple cast over the image you try to capture. Over time those sensors will fail, HTC replaced them with a different design.
In lumia 1020's case the huge heat output results in a another failure mode. Since the module uses gyroscopes and moving parts (bearings, actuators etc) in plastic rail, the plastic becomes brittle with an increase in temperature so the rails change their position relative to the sensor. So it's mechanical wear amplified by overtemperature.
The aufocus lens subassembly will actually swing out of the correct focusing distance. The 1.5-2mm distance will thus increase over time. Since it's a closed space, there's not enough space to accomodate the new lens position, so at some focal lenghts the mobile assembly will bash against the sensor casing resulting the dead penguin sound.
SO..... HOW TO FIX THIS?
If your phone's camera does the penguin sound all the time, then it's done. It's past feasable repair solutions. If it's only seldom happening or only at specific focus distances, you could still be good to go. Also, no penguin sound but only focus problems is the ideal case.
So, what to do. It could come as a surprise but if it were a human, your phone would have a typical case of short-sightedness or myopia. So... let's treat this condition like we would do with a human.
First step: find some glasses. From some experiments i've determined that my phone has a -2 to -3 myopia. So i found some corresponding glasses, placed one lens over the sensor area and voila : the phone now focuses properly. I can take a landscape photo.
So, with that in mind, find some lenses, specified for -2 to -3 myopia and check them with your phone. Try taking photos without using the flash at both landscapes and macro things. A good lens is one that enables the phone to focus at both macro and landscape. Larger negative value lens (-4 -5 etc) could correct landscape focus but prevent the sensor module to lock a macro focus. So.. experiment.
Second step, the ideal lens should be made from polycarbonate, not glass. You will need to cut the center of the lens itself. You can't cut glass with regular tools. If you find the right lens, proceed to disassembe the phone. Once you remove the sensor, you will see a glass lens glued to the back of the phone's casing (on that round black circle on the back). You will need to find a way to replace that lens with your new found one. Ideally, the piece of lens you cut should be as flat and thin as possible in order to make a flush fit inside the casing. Before glueing anything test the lens at the distance it will be mounted over the sensor. If everything is right, remove the original lens using some hot air (it's glued) and replace it with your custom one.
Third step. Improve the sensor's cooling. Some cooper pads should be already placed there by the manufacturer. Use the back of the screen as a cooling surface. Place cpu thermal compound (arctic silver, any good brand) over those copper pads and check to see if they make contact with the back of the display. If not insert some aditional copper pads. This will prevent further heat related problems and further sensor module damage.
Also... NEVER USE FLASHLIGHT APPS FOR TOO LONG WITH THIS PHONE!. When you use them, you are actually powering up the whole sensor not just the led. This can result in overheating and premature damage to the sensor itself.
I have completed my preliminary tests so i'm now searching for a good lens to place inside the phone, once i find one i'll update this post and ad a picture tutorial.
Meanwhile, feel free to experiment by placing different glasses in front of your phone's camera ( 1cm or closer) and check to see what works for you.
Hope it helps :good:
Thanks for explaining this issue. I was wondering is this software or hardware bug but clear now
ok so i found a pair of used glasses. They have heliomate lenses, ie. they darken by themselves when exposed to sunlight but, i got them for free and figured out it's worth a try.
Also in Romania, you can go to a store specialized in manufacturing seeing glasses and buy lens separately. For example a single -2.5 glass lens will cost about 3 euro here and the polycarbonate ones (needed for this project) about 8-10 euros.
But since i have this glasses i used one of their lenses.
First of all, the lenses are too thick to simply place inside the phone. Therefore some DIY action is required.
Here's what i did:
1. First - removing the original lens over the black cap on the back of the phone. I used hot air, that thing is really stuck in there with some nasty glue stuff. Here's how it looks when removed:
2. I then made a drawing of what i must do with my lens to fit inside the casing.
Click on the image to see the full drawing. The first picture shows the new diy lens as viewed from the top, while the second one shows the profile of the lens. This thing is made using a single lens.
3. I removed one of the glasses lens and started cutting a triangle shape on the center of it. You must use the center portion because the thickness of the lens varies and if it's not constant in the center of your lens you will get a lot of barrel lens distorsion when taking photos. Also, you should use plastic lens, since cutting glass lens is impossible with DIY tools.
I cut the lens using a fine saw using a blade made for cutting metals, or you can use a bread knife, the ones that have jagged blades. It's a slow process, it toked 30 minutes to cut that triangle.
4. Now, I've begun grinding the edges of the triangle with a file, in order to begin forming the upper circle that must be inserted to the back of the phone's camera ring. Here's how it looks after the first try.
5. The hexagon shaped part now must have it's corners grinded. Some care must be taken not to scratch the upper and lower part of the lens. Using a spare casing (silver color one in the photos) i checked to see how much to grind in order to fit the part inside. After all of this is done, here's the end result.
6. I've then inserted the new lens inside my phone casing. A little more grinding is needed to align the lens with the case and the sensor. In order to adjust that - we have those 3 blunt triangle edges. I grinded those to make them sit flush inside the casing with the lens being parallel to the sensor itself.
Once the lens was inside, i temporarely placed the sensor over it and tested how some sample photos look. I took some pictures of far away objects looking for edge to edge sharpness or barrel distorsions. Once I found the optimum position i place a little bit of glue on the edges of the triangle to secure the lens inside.
7. Once that is done, i reassembled the phone. Here how the new lens look, as seen from the back.
.
It's a bit yellowish because of that heliomate coating but it doesn't seem to affect the pictures taken.
How this works? Well, i can now focus at things further apart then 2 meters from the camera. I can do landscape photos (that was totally impossible before). Also the new lens doesn't prevent macro focus.
After all of this I've also learned that a -2 lens would have been ideal, because before of this modification i was able to macro focus at about 15-16cm and now i can only focus at about 18-20cm minimum. The lower you go with these lens (-3, -4 etc) the further you increase the minimum focus distance. I don't care much of the lost 2-3cm but if anyone should try this --- try testing with -2 lens first.
Also, some optics stores (in my country at least) can grind the lens for you (i found this ...of course... after i finished all of this) . You give them the old lens you removed and they will measure it and make one from the new lens.
All in all, it took me about 2 hours since the plastic lens are really easy to grind, it's a pretty soft material.
I didn't post photos taken, just imagine a good working sensor, it simply works. They are not that valuable for other people. It's better to make your own tests, at first by just placing a -2 pair of glasses 1cm in front of your camera and try to focus. If it improves your focus, you may want to read this "tutorial" again and maybe give it a go.
thx so much , am having the same problem and i tried an old pair of glasses in front of my lens and it worked , I'll file it and install it as in this tutorial .
Great DIY tutorial,i dont have problems with my Lumia but is good to know .
Specs of the finished product (DIY)
Hello can I know the ff: specs please.
What is the thickness of the glass?
Diameter of the Circle?
I need to do this..
I am asking a company to do this for me so they want some info..
So the only fix for this problem is to.
Change the Camera Module? or Change the Lens with a grade of -2?
Am I correct?
Please response.
Thank you!
thank u for telling. my Nokia 1020 not focusing far objects, so where can i buy lenses type of glass either cylindrical or spherical glass please tell me

Sometimes in low indoor lighting I noticed some dark blobs that appear on the camera. They look like rather large particles scattered throughout the frame. I was suspecting maybe dust in the lens but I've seen a similar thing with my friend's Nexus 4 when is directly cast in sunlight - similar to when you look under a microscope and your hair eyelashes are in the way. Another thing I suspect it could be is some interference from the shiny black plastic ring within the camera lens (not the silver ring outside), as it appears to be made of a rough plastic-like material.
Sample (there are many more depending what angle the light is shining): https://www.dropbox.com/s/zm8h9jp3jhdy726/DSC_0476.JPG?dl=0
Has anyone experienced this as well?
Note that the lens/camera module that was replaced by Sony in Taiwan due to the left blur problem. They assured me that the phone was still waterproof. Unfortunately I am no longer in Taiwan so I can't get it repaired. In most situations the blobs are not visible but I do notice them when I'm filming in my room and the camera appears to be trying to pick up more light.
hmm, now that i look at my lens, i it appears there is a spot on the actual camera lens behind the main lens cover. Either dust got in during the lens replacement process, or it somehow got in later. So much for IP68 =/
Can you send it back and get a new device?

Nope, I bought it in Taiwan, and am studying overseas now. Perhaps next time I go to Taiwan I will turn it in. It's not a huge problem as none of my outdoor photos seem to have this problem - I only noticed it in videos I filmed in my room indoors with a certain lighting or flare (if you cover the light a bit it's gone, like you have a lens hood). It's not as obvious as previous reports of dust in the Xperia Z lens etc.
I looked into it with a magnifying glass and it does seem like there is at least one speck behind the lens cover.
Maybe there was some dust or paper in my pocket that somehow got in, but I had the phone in a case, and there's a rear protector film I applied that goes around the lens
Hello,
Received my Note10+ yesterday, so far love the device.
I just noticed today (this morning) on bright sun / light a gap of couple of millimeters on top of the screen.
Looks like screen is not going to the edge on top side only, is this normal?
Image / full size:
https://screens.urimage.link/20190830_074945.jpg
Please see image for better view / understanding.
Thanks
that gap is for the sensors and speaker
Thank you very much for your time and responding to this thread.
I am a little bit confused, isnt the speaker at the bottom?
I had Samsung S10+ until yesterday, and i do not remember seeing gap like this (its not the same phone, but, probably similar design / i might be wrong though).
Thank you
The gap in the middle 2 arrows are the cut out for the front speaker the other gaps are where the screen meets the frame sometime there bigger on different phones its hut and miss
But if it bothers you exchange it for one that fits a bit better
Thank you very much for responding.
I think i have 15 days to replace / return the phone (i will re-check), but, if its kinda normal, and possible on any other phone, even replacement, i do not think its wise to do it.
Once i put case on, i do not even think it will be that visible (hardly visible now as well if not on bright light).
Biggest concern if this would affect IP68 in anyway
Thanks

I think there is a way you can test the ip rating without obviously putting it in water
Back when I had the xperia phones you could squeeze the device and check the pressure didn't rise and stay risen to indicate its water tight
Thank you again for your time.
I decided to test that gap by pouring water on it for about 20-30 seconds, no issues at all.
I will not bother with this, will just enjoy the phone.
Thanks again.
The picture link is not working. From my understanding the only small gap should be in the center where the top speaker hole is. But the left and right side of the top speaker till the corner should not have any gap. I am having the same issue. I'm going to check to see if other models are like that.
Same, should not be there.
In the end i decided to return the phone.
Upon closer inspections took some photos and judging by other demo units on display. They all have that white line gap. Some are more noticable than others. But same line can be seen. I compared 3 different phones from different stores. They all exist. It's seems like that white line looks like maybe it's the adhesive glue. The middle does not have it where the ear speaker cutout is, where the ear speaker hole ends on both side left and right white line is visible because of the extra gap on both sides and it appears that the line stops before the corner on each side of the glass on the top. It's maybe nitpicking buts it's really annoying. I checked on the S10 it's not present on that model and none I see on the Note 9 too. I checked. And since it's like white color can be visible inside the small gap line on the top where the glass meets up with the metal frame.
I actually just discovered that I can get a piece of paper down between the top of the screen and the frame on my Note 10 +!!!??? All along the top of the glass - from the top left corner to the right?
Is this what you are talking about? And will the phone still be waterproof? (There could still be a rubber membrane that prevents water from entering the insides of the phone...)
Maybe it's just me, or I'm about to get the shattering cam problem on my 7 Pro, but it seems that my camera glass isn't fully level relative to the aluminum, and even less while not in the case. Can anyone else tell me if they also notice this?
Steps to reproduce
Grab your Pixel 7 (Pro)
Place your finger or fingernail on the left (the long pill) camera glass
Swipe your finger to the right, towards the smaller pill/flash
Notice how there is a bump
Swipe your finger to the left, towards the edge
Notice how the bump is smaller, while in my case non-existent
I have got to be going crazy, but while I'm here, if your camera glass broke, what was your experience with the support? Did they replace the phone?
