It's the same as taking a photo in low light, at 1/60 second. That's too quick and you'll have a noisy photo too. Set the camera app to Pro mode and set the speed to 1/60 and take a single photo, with no gimmicks or AI, etc. and see what it looks like.

this is how it looks like on video. only bottom half has noise. if i put it on ultra wide noise goes.
and if i leave it on when it noisy it freezes and says can't connect to camera

Also noticed the noise is there even in perfect lighting . And after 10 seconds it freezes.

That doesn't look good. Are you on an official ROM? Have you unlocked the bootloader?
Is it just on the display you see that, or does the video it records contain the noise too?
Does it take photos OK?

i just received the phone. it's all official. it's on the videos too. pictures are fine also 30fps videos. anything above 30fps has the noise. I think I'm gonna return it.

Seems like a hardware issue, mine is not showing any noise that you have in any lighting condition.
Also i have some other problem, can you check on your device that :-
I noticed that front camera is making face red while clicking selfie, if i cover my face then camera is showing actual colours, but when it recognizes face in the frame it automatically turns the face red, i also disabled all beauty footers but seems there is something wrong with camera software, because gcam port is not showing red face in front camera, can u confirm if you are are also facing this issue or is this alsp can be a hardware issue

it didn't make my face red. if gcam doesn't do it then it's surely software related. the video issue for me happened in gcam as well.

Then definitely you have a hardware problem. That's Strange, it means my miui camera app is buggy, don't know what to do now [emoji20]

Snapchat quality

So I got my S10+ today and everything is great excpet for my most used app which is Snapchat. The front facing camera quality is terrible and it's extremely zoomed in. Whenever you take a picture it also jumps and moves the picture in and out quickly. Anyone else run into this problem
My quality is pretty good but it definitely is zoomed in...have to hold the phone at arms length for it to look normal
Yeah same here, snapchat just did an update that changed a bit. But the problem of the camera being zoomed is still there

how is the quality of the rear camera? I also use snapchat a lot and the quality of both the front and rear camera is very poor in my note 9.

The rear camera is quite a bit better than the front. But it's still snapchat quality and looks nothing like the pictures taken in the camera app. Its decent tho, the front camera situation is still the same.

camera problems greyscale while zoom

Guys, anyone having this problem too? If you zoom from above 1x to 5x (before the switch happens) all pictures from my camera become almost monochrome, I screen recorded what happens.
Check this link, I uploaded a video of what happens to my viewfinder whenever I click the shutter button in zoom option.
Check for example the difference between 1x and then above it

Hey did you find a fix for this? I just picked up a P30 pro and i discovered the exact same behavior with my camera. im seriously considering returning this device because of it!!!
Errrrm, it's a grey cat sat next to a grey cupboard?
Yes, the issue is there on my phone too.... hope they'll fix it somehow
Telephoto lens is a lot lower spec than the main 1x lens, only 8MP
Sometimes for fairly close subjects like that cat and stuff, you're better off using main camera @ 1x and cropping
Help
Hi did you manage to get this fixed? I have the same issue when I zoom the viewfinder is full colour but the picture de saturates when you press shutter
I have been to. Huawei who replaced the camera and I'm still having the issue
Please help if you have the answer
Many thanks
This seems to be a lower specced lens or sensor more than software, it makes the telephoto lens useless.
I have the same problem. To debunk some of the replies, it's not because the cat is grey. It's not because the telephoto lens is of lower quality because it's not used between 1.1-2.9X zoom where muted colors happen and what does "only 8MP" have to do with the colors.
There's definitely a software bug. Like others said, it looks good in the viewfinder but comes out almost greyscale when saving. A bug, just like the main camera being out of focus when zooming back out in video recording. Such simple bugs but still not fixed.
Noticed this too :/
I have this problem too. I had it on emui 9 and now on emui 10. I writed to the support but they think it's hardware defect..
1 year with this phone and the problem isn't resolved yet. And not only that problem, white balance is too blue, the sharpness is really hard, absurd amount of contrast. I'm very disappointed with this phone, because was publicize as "the best photography phone" and It's a lie. This phone do "good photos" if you hate photography.

4k 60fps camera flickering.

I've had the phone for a few days now and overall I'm very pleased with it yet I have one issue. The camera when recording at 60fps at any resolution has crazy flicker. I can record at any resolution at 30fps and it's fine.
I've tried other camera apps on the store but none seem to be able to record at 60fps, open camera for example, won't record at 60fps even when I set it, just records at 30fps.
I'm using the latest eu rom with included camera.
Would appreciate some help, thanks.
Might be an issue with the sensor on your phone. I don't have any flicker with any setting at 4K 60fps.

I just tested my camera - it has no flickering with [email protected]
Whatever modifications that you have made to your phone must be responsible.

I think you're probably correct. Tried it again today and it's working beautifully, I've made no changes or installed anything since yesterday.
Only setting I've disabled since testing was deep process clean, re enabled this to test and it's still working.
Hopefully it will remain working, hard to go back to 30fps video after seeing 4k 60fps.
Ok, so I'm able to replicate the problem.
It's a certain light bulb in my living room that's causing this, it's a 72led corn cob low wattage bulb. Only occurs in low natural light.
Went all through the house at night with the lights on as well as the front and rear gardens and no flicker, only occurs if I have that specific light turned on during the evening in my living room, how odd!
To the naked eye this bulb does not flicker but for some reason makes the phone camera go nuts.
I'll have to check the Hz rating of the bulb.

noise in Pop up camera on k20 pro

I am bringing to notice about a wierd issue with the pop up camera on k20 pro.
Whenever i use the selfie camera ,it's quit and has a gearing sound which can't be heard if you don't listen to it closely and it's normal. But i was testing the fall detection feature of the pop up camera and there i noticed something wierd. Whenever i drop my phone and phone detects fall it retracts the camera as it is supposed to but after retracting it makes a sound which is something like gears jamming with each other. It is audible and doesn't sound normal.
Try it out guys and let me know if this happens with you too.
Perhaps it would be appropriate to indicate also which Rom you are using, on the PE there is a little issue with the frontal camera in switching between video / photo mode, that produce a noise same as yours, in MIUI 10 it works regularly.
Having same issue here
Can anyone is hearing a weird sound in the pop up camera?Just turn off the sound effects and then try to listen to it.Can you hear the same like mine ?
My popup camera produces the same noise.
Any solution? Thanks!

It is normal for camera module in smartphones to rattle a bit.
others have the same problem after the update?
Is has nothing to do with the update. It's probably just the stabilization system.
All the mechanical image stabilization systems I ever used made a tiny amount of noise.
If you can clearly hear more than 3 feet away it may have a problem... or really good hearing
The fact that you can hear it means it's working...

I had this issue while using the camera inside a building, there was shaking from the image stabilization and also the image on the screen was shaking, like blurred. I think this is somehow "normal".
