I recently bought a used note 8 which is taking very noisy (grainy) pictures, especially from telephoto lens. I'm really loving this phone but I can't live without a good camera. Is there any way to fix it?
I guess it is a hardware fault because I have also tried different camera apps. Any help would be much appreciated.
Thanks!

Tried for hours, unable to upload.
Let explain to you:
Pictures taken has so much grain (which comes when ISO settings are set high). I have tried pro mod, it do makes a difference but is very laggy (slow shutter speed)
In short, pictures are too much noisy. Noise is clearly visible in viewfinder, specially when taking close up shots, using live focus or telephoto lens.
Primary lens also has too much grain visible when zoomed in.
I had used iPhone 7 plus which can take spectacular photos, note 8 pictures are worse than iPhone 6's. Definitely not what I wanted
Well, it is still a digital zoom, after the 2X optical zoom. Some of my zoomed pictures look like crap, but others work pretty well.
examples;
Looks pretty good, was documenting the hole in the side of a building. I was about 30 feet away, zoomed in pretty much all the way.
https://photos.app.goo.gl/7MPw7kraX2GyREVk2 <-- Brightly lit.
This one is pretty crappy. Owl was in the basement of my barn, 12 feet away.
https://photos.app.goo.gl/o4I0O8mukoOfBMsj2 No zoom for reference. https://photos.app.goo.gl/47vRH3xgXWXTjFJ02 <-- Not so brightly lit.
Your pics are better than mine.
Of course pictures loose details when zoomed in digitally, but mine is different story. It shows grains even without digital zoom. It shows visible static noise. Your pictures are waaaaaaay better than mine. I might return it today. I'll miss it, It's a great phone ?

Yea, if it's showing grain without zoom, something's wrong with the camera.

Returned it!
I had the same problems. Them I sat it to 4:3 (12M). Turned off HDR, made sure I didnt use live or manual focus and my pictures are great! Check this site out. Youll see side by side comparisons of off the shelf note 8s and Iphone 8s. High end DSLRs require settings changes and different focusing and lighting for some pictures. But they are huge and expensive that they have room for all the mechanisms and sensors that you pay a hefty price for. This is a phone and some places you may have to use pro mode to get the right shot. The phone doesnt always know what a good picture looks like to you and in some cases cant figure out what to adjust to clean up the picture. Practice with pro mode.

Hi all,
several days ago I noticed that the camera of my Mate 9 (MHA-L09C432) is not focusing.
Then I saw at this this thread that the camera module could be shifted.
Because the focus is working in properly in b/w mode I gave it a try.
Today I disassembled my phone (which was not easy) and saw that the bottom part of the dual camera module was slipped out of the fixture for 1-2mm.
After correcting this problem, cleaning the lenses and reassembling the phone I am now able to focus on objects in a range of about 1m again. But if the camera is not parallel to the object it is very difficult to focus...
But the main problem is, that i am not able to focus on an object which is more than 1m away... The object is always blurry and when i choose manual focus I am already on the maximum of the focus range...
In b/w mode everything works perfectly fine!
I cant see any impurities on the color-lens...
Does anybody have similar issues? What could be done to solve this problem? Could a new camera module solve this problem?
Thank you for any help in advance!
I fixed this problem by replacing the entire camera module.
I tried several things but only this solved the problem...
I do have the same problem exactly
So you probably have to replace your camera module...
The Mate 9 is not so easy to open up...

I replaced camera module, and it worked for a few days then the same issue returned. It will focus close up (-+ 1m distance) but far distance 3m to infinity will be out of focus. I can get the camera to refocus correctly (sometimes!) by sharply slapping the phone display face down onto the palm of my hand. It only works face down.
This happens with origin camera lens and replacement lens I installed.
I guess my only solution to have a working color camera on a phone is to buy a new phone that isn't made by Huawei, as a search of Internet suggests it isn't just Mate9 model that has this problem??

Sounds like your camera is slipping inside the bracket... I revented this problem by pressing the camera module in place and carefully fixing it with hot glue... Don't block the autofocus or the lens with hot glue. Only a very thin layer from the edge of the camera case to the bracket is required.

I tried fixing the camera in the 'bracket' as you say - by glueing it down. Its just a space on the board it fits into, so I'm not sure about any bracket. I have now tried it with two camera modules (the original and a replacement I bought). Both cameras give the same unfocused result on anything more than 1-2 m away. Strangely on scenic shots some parts of the shot are in focus whilst most of the scene is out of focus. The front camera and monochrome camera are OK. The aperture option on the color camera doesn't work at all, if I try and edit depth of field after taking photo it has no effect. There's also a setting in the camera app to restore defaults, which has no effect also.
Hi, I recently got my Xperia 5 iii and I noticed whenever an app accesses the camera there's an audible 'click' and I can feel a small vibration in the device.
Does this happen on anyone else's device? Or I got a dud? Pictures seem fine switching between the lenses work.
At 1st I thought it was the magnetic system in the zoom lenses but I don't notice this when switching between the zoom lenses.
Its normal

yes it's normal.....was weird for me to at the beginning.....its theclense working while activating the canera.
I can hear clicking in the cameras when moving with phone quickly or shaking it. Even if camera app is not open. Does someone have that also? I assume it is optical stabilization rattling but not sure. Taking pictures seems ok. Although I notice very little shaking when taking pictures with 70/105 lens. Can someone confirm on your device? Thx.

Everyone has this
On mine, there is also faint electronics-sounding noise coming from the earpiece speaker (when the camera app is open, and the main camera is selected). I assume the speaker amplifier is picking up interference from the camera electronics.
Hi! Xperia 1 III owner here. It's normal that you here those clicks, it makes noises because of the moving lenses in the periscope cam. When you open the camera it move the lenses in place. And when you shake the device it clicks because you're retarded and shake it unpurposely the lenses are moving because of the kinetic forces
normal....no worries
Hello, is the softness/blur normal at the corners or it is a defect?
Optical limits of the lense.
All lens have a blur profile and are not equal across their fov especially in the corners.

I can see some corner blurring in the link shot, normal.
Brace the cam before shooting test shots so there's zero cam shake, use the spen bt as a remote shutter release. The cam's IS may be at play here.
If you look at blur charts for Canon L lens costing thousands of dollars you'll see similar results especially wide angle lens. Blur is a problem when it's not sharp near the center even by a small amount.
You can return it. No guarantee the next one won't have a worse blur profile though.
Vote please
I can't vote because I would not use a shot like that to test for corner softness. Remember the main camera is an f1.8 lens, so it is going to have significant depth of field focus differences. I'm assuming that you used the main camera. In your shot you are focused on something at middle distance, while the right side is close and the left side is pretty much at infinity. I'm just saying that it complicates evaluating your shot for corner softness. You could do a better test by taking a landscape where everything is far enough away that focus distance does not make a difference. Also, Samsung made the s22U main lens a little wider (23 vs. 24mm in the S21U vs. 26mm in the Note 20) so that isn't helping because the wider the lens the softer the corners, generally soft corners are the price for wider angle. Just an opinion.

A simple image isn't a proper blur test.
All lens have corner blur to some extent and this isn't a high dollar lense by any stretch of the imagination.
Here's how a wide angle high dollar prime lense for a full frame sensor stacks up.
A interactive blur chart for a Canon L lense:

Notice how some corners have less blur. No single or compound lense is perfect. Blur is only one optical considerations of the many optical properties of a lense system

This is normal. You aren't aware of it but there's a subtle blur pattern across the whole image.
Blur is always present to a greater or lesser extent.
All lens have this. There is no perfect optical system.

I noticed something strange.. if the corners are softer the middle of the photos almost perfect. If the corners are fine there are a lot of random blurred area on the shots. I think the corners softness is "better
So I can keep the phone if Im right.

A typical blur pattern.
The way you grade blur is by center sharpness, how far it extends and the evenness of the blur pattern. Unless you're looking for it, it blends right in. If it really bugs you, crop it out.
The worst spot for blur is dead center, hard to work around a soft lense...

Ok
I have two snapdragon s22 ultra one purchased last week another a month ago
Whenever I reach 10x zoom slider (either directly or even by sliding, from any lens) it switches to 10x lens for a split second and then switches back to 3x lens and zooms digitally.
This happens irrespective of lighting conditions and distance of subject.
Comparing both my s22 ultras side by side I was able to confirm that this problem exists only in one of the phone and not in the other model that phone keeps 10x optical zoom and does not switching to 3x zoom.
Options
A. Any solution to this problem would be highly appreciated?
B. Want to keep formatting as last option.
C. The phone is just 7 days old shall i take it to service centre.
One possible clue, I can make that happen on my S22U in situations where the 3X lens can focus, but the 10X lens can't, for example something about 6 inches away. Then the switchover is delayed as you zoom until about 14x. I'm not sure if it is using the laser ranging for that situation or not, but possibly if the laser thinks you are close, for example taking a picture through glass on a window, it might not switch to the 10x lens until 14x.
But as I said I have another unit at my home.. thuis one constantly switch only after 15 x and not 10x. The other unit is doing perfectly fine for same subject

Return it. I had a similar problem with a Verizon 10+5g with the wide angle lens. Frequent camera error messages turned into always camera error message when selecting wide angle. Sometimes a tap on the corner to a hard surface would fix it but that stopped as a solution after a few times.
I would say if possible, return or change it. My first one was no issue with camera but heating issue.. replaced one; Most of the time randomly pick the regular lens instead of 10x lens. Also at 10x zoom color suddenly changes to fuzzy and dull.
Replaced. This one no color issue but 10x n 30x n 100x has focus issue. Cant focus correctly, output image is most of the time blurry which my first ome had no issue. But i decided to keep as i dont have that time to go n chamge again. I also don't keep phone too long, and i rarely take pic.

How can we know which lens is being used by the phone at 10x? I want to confirm if my unit is not faulty.

After taking the picture check in the picture details the focal length:
10x lens has 27,2 mm
3x lens has 7,9 mm
1x lens has 6,4 mm
0,6x lens has 2,2 mm
You can also just put your finger in front of the lenses to see which one it is using.
I have the same problem here
Any way to solve it?
I've seen this happen in low light. The Periscope 10x zoom is f/4.9, while the 3x zoom is f/2.4. I don't know what the optics of the periscope are, but with the extra reflections/prisms the "t-stop" is probable closer to 5.6 for the periscope lens. That means that the 10x lens gathers approximately 4 times less light, and sometimes the phone seems to stick with cropping the brighter 3x lens in low light because there just isn't enough light. Sometimes in really low light it seems to use the main lens as well.

There is definitely some weird logic that dictates which lens it will use regardless of the zoom level that you request. Is there enough light, can I focus, is the subject too close for the 10x lens or are they shooting through glass and the laser misreads the distance as really close; if one of those things is true it switches lenses.. It happens when you try to take a macro shot too, you can't really control which lens it is going to use and a lot of times you get a crop view that is lower quality from one of the main lenses instead of what you wanted. I've played around with it a lot, and I'm still not sure exactly what it is doing. For example, start out with the 10x zoom about 10 feet from something, then move closer and closer. At some point you will see a little jump in the image as it switches to one of the other lenses without telling you. Then back away slowly, and it does not appear to switch back, keeping the crop from the other lens; I don't know when it switches back. Still, it should not happen all the time, especially with good light and a good subject that is far enough away for the 10x, it COULD be a hardware problem with your device but you also could be falling victim to the complex logic they are using.
Hi All. Similar problem. I was taking close ups of flowers using the PHOTO mode... I had blotchy results at 10x. I did some investigations. It turned out that when using the PRO mode, all was well. I first thought that it was some weird image processing that Samsung did, but that's not true. The truth is that the phone used the 3x camera at 10x magnification on the PHOTO mode! I then discovered that it only switched to the telephoto lens at precisely 15x magnification. Very weird. I can get very good results at 15x. But, when using PRO, the switch occurs at 10x. Samsung - what is going on? It looks like purely a software issue? Paul
Update: I've just restarted the phone. All back to normal and as intended. Lenses switch at precisely 10x.
Update 2: No, this is not due to a restart. The same issue again. The switch sometimes takes place at 10x, but if the phone is to close to the object, the switch will take place at precisely 15x. Super weird and inconsistent.
Update 3: Ok, so the switch between the lenses (on the PHOTO mode) is dictated by the distance between the object and the camera. If the phone is too close to the object, the phone will want to use the 3x lens. Absolutely no issue for long distance shots. These switch at 10x. You have to be super carful with telephoto closeups as you can basically ruin the shot thinking that you are on the 10x lens but in fact you are on the 3x lens. The PRO mode does not have that issue, but then changing iso and shutter speed are a bit hit and miss as well.
Worst still, this is also happening on the VIDEO mode.
For me the middle lens out of three is used for 1&3 zoom and small lens under flash is used for 10x in standard mode. At least kind of, seems to switch depending on distance and also the lower of the three is used for 10x sometimes......
When in pro or expert raw it behave less erratic and uses the lens I choose.
Highly annoying tbh.
I recently discovered this issue and its really embarrassing. Not many of us will go into pro mode and fiddle but as a simple point and shoot. This is terrible.
I am on the latest Software AVF7. My 10x photos keep looking like trash and there is a lot of light around. But i discovered that if you open a picture within the gallery while at 10x zoom and return to the view finder, it switches to the optical and stays. Has to be a bug rather than a defect.
It doesn't seem to be an app bug. I am also on AVF7 and cannot replicate the fault. If it is an app bug, then resetting the camera, clearing the camera app's cache and data should clear it up.
How to verify if this problem is also on my default samsung camera? As far as I'm using my phone, I saw nothing wrong with those zoom lens, but just want to check to make sure.
