Lens problem - Nokia 7 Plus Questions & Answers

I reallized that in low ligth situation when there is a ligth bulb the lens gets like yellow points in the picture. Like an imperfection in the lensif you move the camera they can get bigger, it is really anoying. I want to know if it is just mine or is a common problem! Thanks a lot!

No one can check this? I think it is not demanding, just try to use the camera in the nigth with ligths bulbs! Thanks!

Same for me. These pictures were shot from Gcam port. The reflections can clearly be seen on the road.View attachment IMG_20180711_192313.jpegView attachment IMG_20180711_192308.jpeg

I see dots sometimes with mine too. I wonder if it's some sort of weird reflections caused by the 2 lens system, perhaps light is bouncing off the other lens or something. Haven't had a chance to test out this theory yet. Could try covering the other lens with tape or something.....

Thank you both. I was almost sure it was a common problem. I think it is a problem with the optics, in particular the lens. Google pixel has a similar problem i think. It is really ****ty because you can't make good pictures at least you edit and delete the spots. I do a lot of test, like blocking the ligth, trying with blocking one sensor of the cameras, it is not fixeable i think.

[Q] Rear camera blur problem. Anyone?

This is my first post here, so first of all, hello everyone and greetings from Finland!
I bought the IS about two weeks ago. Today I took my first outdoor pics and noticed a strange phenomenon. If I focus on a distant object (typical for outdoor shots), the extreme right-hand side of the photo is quite mushy and blurred. The affected area is only about 200 pixels wide (starting from the edge) and goes all the way from top to bottom. Everything else, including the left side, is tack sharp (well, as sharp as it can be with this camera anyway). This happens with every photo, if the focusing distance is relatively long. Close-range shots (indoor pics, for example) are just fine, also the right-hand sides of the photos turn out sharp. This is very strange.
I'm a very experienced photographer, so it's not my technique. Something is wrong with the optics alignment, sensor or it could be a software issue. With optical problems the close-range shots are usually more problematic because of short depth-of-field, which makes the alignment errors much more visible.
Anyone else having similar experiences? Take an outdoor shot using a focusing distance of, let's say, 20-50 meters (or yards) and see if the right side of the image is as sharp as the left side. Make sure there's something with lots of detail near the edges of the image. I would be much less worried, if both sides of the photos were softish. After all, that would be quite typical for less-than-stellar optics found in camera phones. It's the asymmetry that bothers me.
This is actually my only gripe with this phone. Apart from this unpleasant surprise I really like the IS.

P.S. No fingerprints on the lens, it's clean!
There's an ongoing thread about the camera quality issue.

Thanks for the tip!
I did a bit more controlled experimenting and sadly it seems that also close-distance shots suffer from the same right-hand side blurriness. If I take a photo of a completely flat surface, focusing on the center part of the viewing area, the extreme right-hand side of the photo is soft. There's nothing wrong with the left-hand side. Also, the affected area is almost 400 pixels wide (wide angle setting, no zooming). I also rotated the phone 180 degrees and took comparison shots. And...the left-hand side was blurry.
Maybe I have a bad sample. I can't exchange it for a new one, so I guess I have to live with it or have the local HTC service take a look at it. I'm not too keen on doing that.

Nothing like this in mine. Photos are good. No blur at the right.

Thanks for your comment, good to know your camera is working fine!
I'm suspecting there's dirt inside the lens assembly or on the sensor. My IS is now being serviced at the local HTC service center. I'll let you know how this turns out.
Guess caused by auto focusing

Possible camera defect

Camera quality on my Xperia Z is great apart from the corners of each picture (especially the top corners), which are always very blurred compared to the rest of the image. I've tried all sorts of different settings, seems to make no difference.
Does anyone know if this is just the way things are with the Z, or a defect which they might fix/replace under warranty?

The design of lenses have this inherent fault, corners are always more soft than the center.
However post some shots so we can see, because if you are claiming that they are very blurred it would be good help diagnose if the quality does seem worse than the norm. Also double check that the lens is in fact clean all over.

Ok thanks for the heads-up but I could just as easily have posted this as a thread (i.e. 'Possible camera defect', and without the 'Q'). I wasn't aware of the restriction on questions here.
Let me rephrase: "It seems to me that there's a defect with my camera which blurs the corners of pictures. Does anyone else have a similar experience with their camera?" (Or does that count as a question too?)
Here are some links to pictures, anyway, assuming the thread doesn't get deleted (and thanks to those who posted asking for them):
As long as there's nothing in the top corners, it takes really nice pictures:

But these three (taken to test for this fault) clearly show blurring in the top corners (comments on whether this is excessive are welcome):

I have the same problem. When I'm holding the phone in landscape mode, the left corners are also very blurry.
I experienced the same problems with my Xperia Neo, but in contrast to the Xperia Neo, the Xperia S didn't had that problem.
I'm very disappointed in Sony, because I have more problems with my Z

Bump - does anyone else experience blurring in the top corners of their pictures? Thinking about returning under warranty, as I use the camera quite a lot. Sample photos linked below...

I'd say send it back, must be a hardware failure.
I'll be sending mine back for dead pixels on the damn sensor. New sensor so lots of problems.

I do not see really problems with this, I am sure it is a slight misalignment of the lens, this happens on P&S cameras, they are typically worse than this in all corners. This effect even happens on some of the most expensive DSLR lenses, the more wide angle typically worse the issue.
If you can get the whole phone replaced because of this then you will be extremely lucky.

Spots on camera

Hi
I have a camera issue on my note 8. At night time I get these bright spots near any bright light source. I've attached a picture to show this. The spots move position on the screen as I move the phone around. Anyone else got this? My camera lens in clean.
I believe it is from the refraction of the light thru the glass over the lens. Happens all the time with a bright light source going through a filter or other glass materials.

Thanks but I've never seen this before. Can anyone else replicate this?
try wiping the camera
I tried wiping the lens - it is clean and clear.
Here is a video of the problem - the movement of the spots tells me this is not a hot pixel on the CCD but something else bobafx is likely right about refraction, but I have never had this issue with a camera before.

im currently talking to samsung on chat about this...
I have the same issue with my note 8. So i checked other Samsung phones, 3 different galaxy s7, galaxy s7 edge and galaxy s8+. All of the phones have the exact same dots when in low light near a light source.

I'm still not seeing this on my cameras. I've been going out in front of my house at night and shooting inside my house and at the gas station and other spots during the night and I'm not seeing it.
Got the same problem, strangely enough I've never noticed something like this in my Note 5 so I think this is specific to either my unit (or a batch) or the entire Note 8 model.
Now I can't test my note 5's camera as the glass is cracked.
Attached are some sample photos from me - I must admit this is a pretty annoying issue.
I need to find someone at work with a Note 8 and do a direct comparison. If I succeed, I'll update you guys with my findings.
@msx999 Let me know the result of your contact with Samsung (if you ever have any) please.
Are you talking about the light from the street light reflecting from glass back of the phone and hitting the street? Maybe because back is like mirror and reflects light back, like a mirror? It would be easy fix, put the cover on, or tape something non reflective on the back as a temporary fix. Either that or I'm not seeing what you see.

Hi pete4k, I'm talking about the light reflections from the car's lights and the street lights as highlighted on the photos.
You can move the location of those reflections just by tilting the phone - it's happening within the lens or between the len's glass and the image sensor.

Hi Maciekd
I still think at least some of the pics show reflection of the street light off the back of the phone, acting like a mirror. The angle and shape of the the reflection seem to be right. But maybe I'm wrong, maybe it is something reflecting inside the cam, but I have not seen it on my pics to investigate more, however I did see the light reflections off the back, so was thinking maybe it's the same, but if it's not, it's not.
I think this is indeed reflection. But I don't think eveyone is having the same issue.
I think this might be an issue limited to my unit or maybe some batch.
Dot defect reflection problem on note 8
I have the same problem exactly.
Been replaced the camera part and the result is still the same but minimize the dot's size only. But still annoying to have this problem at the note 8 compare to its price.
Even before clicking take shoot or recording, I can see there are dots in display.
just wondering. Not all unit have this issue. I've seen a post that no dot defect at all from other forum.
So it maybe only some unit have the problem.
Will going back to Samsung service center and ask a replacement unit. See if approve or not.
The same problem, note 8, Europe, bright moving spots, never seen before on older models...
Same
Yes..Same thing for me. Only when you are shooting something that is directly flaring like lights or something blindly at night but once you out focus them. The camera is just fine
everytme i take a night time video with lights near by I get these tiny dots... look at link below for more.

guys is this a physical defect? I need to know asap..

Not perfect but very disappointing.

As much as I love my phone, I have spotted a few things that made me question the phone or Huawei.
First of all, I was playing with the three rear cameras and noticed that when I hovered my finger above the topmost camera (I think it's the 40mp one) or covered it, my finger didn't show up. Is that supposed to happen?
Secondly, when I take a picture in complete dark, there is always some noise present.
Thirdly, the screen has a gradient hue, darker on the left side as compared to the right. I have attached an image in this post. Please check for the gradient as I seem to see it on my screen. This is clearly obvious in a complete dark room.
Please check your phone and let me know if you're facing the same thing. Thank you.
The top one is used when zooming (5x) i think.
But funny enough the live view seems to not always use the same lens as the lens the photo is taken with.
If you zoom 5x and cover the top lens (or even when its dark ?) the live view switches to the main lens.
Sometime you can catch a glimp of your finger just before the switch happens.
And then when you take the zoomed in shot with the top lens covered you get a black picture, although the liveview shows an image.
I tested this in a fairly dim living room, so your mileage may vary if you test this in a bright office or outside in the sun.
For your noisy dark pictures. If you take a picture in a completely dark room (covered your screen ?) then the ISO is probably cranked up to the moon. So your going to see noise.
Maybe try in pro mode with a sane iso and exposure time (to avoid noise and hot pixels) and see how much noise you get then.
Yes, it seems so that when I zoom while covering the lens, the picture comes as the lens is covered. Thank you for clarifying that to me.
Can you please, if you don't mind, clarify the gradient hue of the screen? Or is it just mine? Thank you.

Others have answered your finger question. Not really sure what that point was about anyway?
Re: noise. What were you expecting? This isn't a full frame DSLR shooting raw. This is still a tiny sensor (just less tiny) with a highly compromised lens (miniaturisation comes at a cost). However, it is in my view head and shoulders above any other smartphone for delivering photos in poor / mixed light and at night when hand held - CM1 & 808 still beat it easily when on a tripod or similar.
Re: the screen. There will always be some gradient. If it's bad, I suggest you talk to Huawei or your provider / retailer's support and get a replacement. But since you say you only see it in a completely dark room, I can't imagine this is worthy of replacement.

It's my first oled phone so i don't have any reference on how good oled is supposed to look in very dark rooms.
If you can only see it on dim images in a dark room then your probaly noticing the "mura effect".
I cannot tell if your display is particulary bad or not. But i to can detect it looking at a uniform very dark gray backround in a very dark room. Under minimal light conditions i see no problems.

Edit : i checked your blue image , but my eyes cannot really spot any meaningfull hue differences even in a darkened room.

The top lens is the tele lens. It only has 3x zoom. The 5x zoom is a hybrid zoom where it uses both lenses.

Is the secondary front facing camera real?

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.
