Telephoto camera yellow tint - Huawei Mate 20 Pro Questions & Answers

I recently got a Mate 20 Pro and all seemed fine, including the screen.
I recently noticed (indoors especially) the Telephoto camera has a strong yellow tint. It's not possible to set the manual white balance far enough to counteract it.
Thing is, if I shoot RAW, the colours are normal and in line with the other cameras, so I assume this is a software bug.
It is most definitely using the 3x lens as I can see my finger if i cover the lens.
Has anyone else experienced this? It seems to switch to the actual 3x in lowlight over using the primary camera and cropping. Isn't this backwards? It seems to rarely use the 3x camera.
This thread was the only thing I was able to find in a similar vein.

Having said that, it doesn't mention the yellow tint.
For information, I have the LYA-L09 on O2 UK, with 9.0.0.153.
Thanks for any help in advance!

How exactly does the S9+'s telephoto lens work?

Hey guys. So I've been tinkering with the S9+ and its telephoto lens and I've noticed something weird about it...
So basically, I got one of those clip-on lenses for when I still had my S7. So I figured if I used the 2x on the telephoto, it would get 4x. Odd thing is when I switched over the 2x and had the clip-on lens on the main (top) camera with the telephoto lens effectively covered, it still shows an image (which actually looks 4x!). So does that mean that the 2x still shows the feed from the main cam? Doesn't the telephoto lens have its own sensor?

The telephoto is used only when it detects good light conditions, otherwise, it will be a crop of the main sensor.
You can do the test yourself: in good light conditions, change to the 2x and you will see is using the telephoto sensor; now cover it with your finger and you will see your finer approaching and after a couple of milliseconds you will see an image again. This is because the camera detected no light in the telephoto and changed to the main sensor.
Take out your finger from the telephoto and you will see how it changes again.

low Light problems photos from stars distorted with S9Plus

Hello,
i take photos from the night sky since serveral years (with smartphones too).
Unfortunately with the Samsung S9plus the stars are not pinpoint like as they are on the Samsung S7. They apear very distorted with a kind of a halo.
Ofcourse the smartphone was not moved during 10 seconds of exposure time.
I did layed it down and used the self timer mode to prevent shaking.
I tried it serveral days in comparison with the Samung S7.
The S7 is always much better and show pinpoint like stars.
The distortion of the stars is visible in the RAW files(DNG) too so no jpeg problem forced by the compression.
Could you reproduce the same problems?
I am not allowed to post links.So how to show you the photo?
Could send you the link of the uploaded photos for comparison.
The dual camera variants of Samsung phones tend to overexpose shots, especially during darker environment.
That's what I noticed, and I'm waiting for the update they sent to Note 9s.

Are you using the telephoto camera? It has OIS driven by digital gyroscopes. Those gyroscopes aren't effective at low frequencies so the OIS will slowly drift around a small amount. 1/5 second is usually the limit for sharp photos. Even when the gyroscopes are turned off, OIS lenses are VERY sensitive to motion because of the lens being on a soft suspension. Walking next to the tripod could wobble the lens.
You also can't expect clear images if you use F/1.5.
Try using the wide angle lens.
I would send a photo to someone of you so you can post it here into the Tread.
Who like to do it?
The camera was layed down on the ground so no shaking or vibration ppossible during the exposure time.
I found no setting that the OIS gyroscope is working in photo mode. OIS is probably only working in video modes.
Even if it works in photo mode, the camera was layed down, so no shaking could happen.
Who of you could make a photo from the stars with the following settings?
Pro Mode
Camera mounted or layed on the ground with direction to the night sky.
Self timer to prevent shaking
Iso 800
10sec shutter speed
F 1.4

Antwort unfortunately the tele lens only works in very good light conditions.
Even in a bright lighted room there is no way to activate the real Tele lens. The camera automatic switch to digital Zoom.
Also in pro mode its not possible to use the telephoto lens if the light condirions are not perfect.
This is very bad because if the cameras is standing still completely and the object doesn't move why not using the Tele camera lens in pro mode?
Very interesting Thanks for the link

Telephoto camera bug - Phone always uses normal camera at 3x zoom

I first noticed that my optical x3 photos had a fair bit of digital noise to them.
I then tried pinching to change the zoom and I couldn't see any transition between the lenses when going from 2.9x to 3x. You should be able to clearly see the transition between 0.9x and 1x
After covering up all the lenses one by one with my finger and changing the zoom level, I can see that the x3 view (which should be using the bottom left lens, as you are looking at the back of the phone) is only blocked when I cover up the standard lens (top right)
Can anybody else verify this? Is this some strange intentional behaviour or a bug?
Confirmed on my device too as a bug when viewing the screen.
However, if I try taking a photo the camera switches to the 3rd sensor to actually take a photo.
Must be a new 'improved feature'.

IMHO I suppose it's so by design, to allow the user for a smooth zooming experience, and it can be considered a bug only as far as the correct lenses are not used to take the final picture.
I think it's to do with the minimum focus distance to be honest. If you're trying to focus on something far away it will switch but something close it will switch back.
I think, the camera changes at zoom 3x if there is enough light, otherwise it will use the main sensor. I tested this by holding the camera on TV and on my low board, the room was dark.

Mate 20 Pro Camera/Lens Problem ?

Hej guys, I was wondering if my Mate has a problem with its lenses. As far as I understand it, there are three different lenses for wide, normal and zoom. The zoom lens is supposed to be the one under the flash.
But I can't activate that lens. Yes, I can zoom 3x, 5x. But the picture still comes from the normal lens, which I found out by putting something in front of the lenses to see which one blacks out. The lens under the flash is just never used, no matter what zoom setting I choose. So it seems like the zoom images are taken with the normal lens and digital zoom instead of the zoom lens.
Am I missing something? What do I have to do to activate the zoom lens ?

Camera 📸

hello, I noticed that the middle lens is useless, while in the screen I tested the 3 lenses by changing the mode.
Hello,
The second camera is the 50mm equivalent lens, aka the x2. It only works if there is enough light, else the phone just do a crop of the main camera. No way to force use the x2 on the mark I.
