Firstly, I have the last emui 10 update for this phone.
I haven't checked this since I bought the phone. About two weeks ago I checked it, I had my main camera on, covered the camera and its working.
I used the 3x zoom and covered the zoom lens, and it turns out, the main camera was on again. Shifted to 5x zoom and the same thing happens. Turns out the main lens is used for zoom and not the zoom lens.
I checked out the monochrome sensor, closed the mono lens and it was working.
The only lens not working on my phone is the zoom lens. Do any of you guys had this happen? Can it be fixed?

How does the zoom actually work?
From the specs both colour lenses are fixed, so below 3 times, is this simply digital zoom on the wide lens?
At 3x it also does not seem to always switch to the telephoto lens. Why?
I bought the phone for the camera abilities but currently question whether they work as advertised.
One review mentioned Open Camera as a better alternative, so I tried that, but from testing, that seems to never use the telephoto lens in any conditions?
I notice as well that apps like Lightroom do not pick up an option for the second lens either.

Hi, I dont claim to be an expert, but I think I can answer your questions
Yes, any zoom level below 3x is effectively digital based. It's not a straight crop so you will get better results from using that zoom than cropping in to a wide shot later.
For 3x zoom will use the tele camera provided the subject is far enough away for it to focus, and there is enough light. i.e trying to take macro-type shots with the zoom lens is a no go, and in low light the software will use the big primary sensor as the tiny sensor used for the tele would just give a noisy mess of an image.
N.B: The image preview shown in the app when zooming doesn't always update to reflect the feed coming from the tele lens. (you can normally see it transition) when you actually take the image, it will use the correct lens for the conditions, even if the preview suggested otherwise.
Seems that third party apps can't access the other sensors, at least for now.
Finally, the same as above it true when recording video. Contrary to what some sites have reported the phone WILL switch to the tele camera for zoom levels of 3x+, and can do so whilst recording. The same applies as photos, 1-2.9x will be digital zoom (and for video is does appear to be a straight crop, no clever digi-zoom). In this range the quality is pretty poor, so try videoing a 1x or 3x only. (note the tele cam has ois which is great for shake-free video)
Thanks for thr clarification.
Think I understand better now what is happening!
I had also emailed Huawei support and their response was basically the same.
Think it would be good to have this clearer in reviews and spec sheets though.
I am generally happy with the camera but bought it to use the 3x a lot for close ups, which seems to be one scenario where it may not be using the actual tele lens in full.
Thank you!
I've been having same issue all day with my new P20 pro and been thinking that the phone or app is broken. So pleased the 3x works like that. I'll now try test it. ?
Thanks for giving this response. B&W sensor on it is insanely good so I was bummed by the broken 3x
Switching to 3x optical zoom when pressing its button is not instant. You can check that : when pressing the 3x the camera applies a digital zoom and when it gets stabilized that is when camera had switched to optical lens. By night the optical zoom will no longer be working, maybe due to aperture of telefoto lens limitation.
3x times zoom lens can't be used closer than about 30cm either as it has quite a long minimum focus distance.

Hi everyone,
I just reinstalled the Android 9 update on my dual sim p20 pro. When I tried to film in selfie mode with the highest resolution setting FHD+, I noticed a big horizontal line. Does anyone else experience the same glitch?
Hmm, no i dont have this but i guess this is why its called a beta update Have you tried to clear the camera cache and data?
Hi, I cleared it now but it seems to be the same. I did not have the beta update, I actually received the official 9.0.0.106 update. However, it seems to work just fine in open camera. So it seems to be a software issue for me...
Very interesting though. I just found out that if I activate stabilization in open camera, I get a similar effect but on the edges.
Wow, this phone has such garbage software. I hope this is the last thing I post about it but I just found out multpile things. First of all, all three lenses from the back are OIS capable but none of them use it except the telephoto lens, this means when zooming 3x (http://www.mobilenewsmag.com/huawei-lies-about-the-optical-image-stabilization-on-huawei-p20-pro/), but only in certain conditions. The green lines that appear on my selfie footage are from the digital stabilization algoryhtms badly applied. Also, when recording FULL HD, with 60 FPS, the telephoto lens does not work no matter how much you zoom. If, however, you select FULL HD with 30 FPS, digital stabilization kicks in for the wide lens, it crops my footage in order to compensate for the jittery movement instead of applying true OIS which it can do, and only then does the telephoto lens kick in at 3x zoom. Another "great" thing is that when filimg 4k, the crappy software also kicks in and crops my image making it much smaller than in live view, and it applies blurry digital stabilization... Worst decision to spend my money... never again buying chinese phones.
Hi guys,
A couple of weeks ago I realized that my telephoto Note9 camera is behaving weird in Photo Mode.
When I switch the tele on (by zooming or by that little button) the focus is not clear and it looks like the focus module is working hard on the back on my phone. I can hear a constant vibration coming from the camera module.
This is not happening all the time.
It started to appear after I installed a SW update that brought in the night mode also.
This does not happen in Pro mode. In PRO mode all is fine, no noise, no autofocus issue with tele camera. Only in Photo mode.
I think it is a software bug.
Any idea?
Hi, I got my p20 pro as a 2nd hand/used phone.
So if I understand correctly, the top camera/tele lens is supposed to give a better image quality than the main camera's digital zoom, right?
Mine is the opposite. The tele lens...well....sucks big time. The image quality honestly looks like the image quality of a phone from 15 years ago. The digital zoom of the main camera is way better looking. The video in the link below is the video capture of the moment when it automatically switched to the tele lens. Everything seems blurry and glowing.

Physically, I can see that the lens is a bit murky, by shining a small flashlight directly above the lens. Anyone have a tip on how to clean the lens safely? Or is the only option is to replace the whole camera unit?
I found a replacement part on aliexpress, and watched a video of the replacing process on youtube. Seems simple enough, can a layman like me pull it off (replacing the part myself)?
Thank you in advance.
zoom outside on cars or trees not inside on an table.

Hello, thank you for the reply.
Actually that's the first time I noticed the problem, when shooting outdoor in bright daylight. I just didn't screen record it at the time.
Made another screen video, shooting in bright daylight, at 1 PM:
