Small stain in photos with flash, lens 1x (bug) - Huawei P30 Pro Questions & Answers

I think I discovered some bug that happens when you take a photo with 1x lens with flash (no flash no issue).
I'm using version 9.1.0.124
I'm telling this because first I thought I had a faulty photo sensor, but then I took a photo in RAW, and the issue doesn't happen.
So in the first photo you can see a small light stain in the bottom right corner, this is jpeg produced by the phone.
The second one is the untouch RAW, there's no stain, neither in post-production I can make it visible.
So I think it's some kind huawei auto filter/tune for photo with flash that produces this anomaly. I already know of some other p30 pro user that was the exact same stain.
Could someone else confirm this.

RAW
For some reason the jpeg from the RAW doesn't appear.

Update
The store device doesn't produce the stain, so I went for a exachage, the new model was the stain.
So I'm not sure if is software or hardware, for what I know, 3 models have it 1 no.

[Q] Broken camera?

Hi,
My camera shows a very clear lighter rectangle on every picture taken and also live in the viewfinder. It's very visible on darker or HDR shots and less on pics taken outside.
I posted an example picure below. It also seems to be related to the temperature of the phone (e.g. long in use or not). It looks like condense, but it's not because the shape is alway similar and it's been on every pic for a week now.
I'm very hesitant to send it in for repair since I just got it and don't want to wait weeks for the phone to return, but it's very annoying!
What is your opinion, can it be a software bug the will be fixed soon or is it a broken camera sensor? Have you ever seen something like this before (the repair guy from the shop didn;t...)?
Thanks.

camera flash/white picture?

Recently just got a moto x, I have looked but couldn't see a solution to this. When I take a picture with the flash white objects just seem to go crazy white hue, then if I try to take a close up of something with flash on the resulting photo is just a white screen. Is this a hardware or software problem?
for some reason moto built this phone and didn't care much about the camera quality actually the camera is fine but the flash qualities crap mine flashes about a second before the damn picture snaps which renders the flash useless, I have two moto xs they both do the same thing. snap to take the picture the flash flashes then goes out than the picture snaps.. gonna have to put up with no flash until the chinese start putting better cameras in motos phones
The camera is OK in outdoor conditions, indoors mine has black wavey lines going across the screen which get captured when photo is taken. This plus the flash issue issue is just a joke, I know it's just a phone and not going to be like proper camera. Big mistake selling nexus 5 for this phone.

Camera switch problem

Hi.
Ever since I received the latest update (.153), my phone does not switch the camera to the 5x all the time. It only changes, 100% of the time, when I press on the 10x zoom.
I have a hard time explaining, basically what I want to say is: When I press the 5x zoom button the app stays on the main sensor and doesn't use the 5x one all the time, only sometimes.
Try to go to settings>apps>storage and then clear data, it should fix it, otherwise, go to the service center.
Or maybe your subject is too close or you do have a low light environment
Just checked mine and it works 100% okay, so it's not a "global" bug.

Well, it happens only in low light and also when its too close, but still, why?
When I tried outside(in the night) it still used the main sensor, but when I tried using the x10, it was sharper than the main sensor at x5, so I dont understand their logic.

Because focusing has minimum required distance, maybe at least 2m-3m when you use 5x optical zoom to properly focus on the subject (Even DSLR/Mirrorless lenses has it). Also, it will shift to main sensor at night because it has only 3.5 Aperture and it will be too dark if it will use it compared to 1.6 aperture of the main camera. Same how samsung uses its telephoto lens at night, it will automatically shift to main sensor.
In contrast, 10x zoom uses hybrid zoom which uses both the periscope lens and the main camera. So far, my device is good in lowlight even I use 5x zoom, I think you just need to focus it firmly before taking photos
I've noticed the very same issue after .153 with mine, I've cleaned data for camera and reset it to default which immediately fixed the issue, but now it's happening again... and not always, it seems like it just can't switch to other camera module... when needed (5x only) both for video or photo... really strange... Mine is from UAE...
Yeah, same here... But I can't even fix the issue.
It keeps struggling with 5x zoom.
When it starts focusing, often a noticable switch (different camera module?) to a much noisier image occurs.
Also with zooming in from 1,1x to 4,9x I have no image stabilization...
I hope they can sort this out with future updates.
For now I have to use 5,1x zoom or 10x zoom for a clean image with stabilization.
Can anyone confirm that behaviour?

Camera Problems

Hi,
Currently in the .153 firmware and have noticed a couple of camera problems and just wanted to see does anyone else have the same problems or know a solution.
First problem I noticed is sometimes when I take a picture and go to view it using the gallery button in the camera it will say "loading" and it will stay like that and then I'll either get a could not connect to camera error or the camera will crash and the picture won't be saved. This seems to be solved with a reboot.
Secondly I noticed that when using the 5x zoom it appears to not use the dedicated zoom lens and instead using digital zoom from the main lens. Clearing the data and cache fixes this issue for a period until I comes back.

I have also noticed the zooming not using the main zoom lens you could hear it before but you cant hear the lens anymore since the update so they have bust the camera in the update ?
Mine seems to zoom okay
When there's not enough light for the tele lens to expose correctly the phone will switch to the main lens and then apply digital zoom. This is because the main lens has higher aperture (lower f/number) and therefore it will let pass more light to the sensor than the tele lens

I don't think this is the problem for me because I noticed this happening outdoors in nice sunny areas.
The latest updates has many camera bugs even using light painting mode. Silky water feature does not work very well even in other light painting modes which produces around 700kb file only instead of more than 2mb.
SO how does that 5x optical zoom work? Everything beneath 5x is not optical, is that right? Or does it depends on the light conditions?

Most of the time, 0.6x, 1x and 5x zooms are purely optical, any other zoom is not. But as stated before in certain light conditions 5x can be non purely optical
I've noticed the same issue with the camera lenses and was surprised, that the quality of the results differs a lot even with the same focal lenght!
The phone does not always chose the lens you actually want to use. I did a few tests on that by covering each lens when changing from wide to 1x to 5x (that 10x is digitally zoomed is obvious). Everything in between is digitally zoomed (or cropped?) as well of course.
Please see attached pictures. Both on "5x" - 135mm focal lenght, but of course with different aperture (F3.4 vs. F1.6), exposure (1/30s vs. 1/120s) and ISO (200 vs. 80). This indicates quite accurate, that the phone uses the main lens (1x) with digital zoom in some situations, which is a mess! You cannot force the phone to use one lens, that's the issue, even in pro mode. It seems the phone decides which lens to pick on the available light (of course the main lens has the larger aperture), but digital zoom is a really bad solution!
As you guys mentioned, this issue is the same with videos!
I have not found any solution or how to chose one explicit lens. Hope an update will make that possible...
I'm on 153 also but didn't have any problems with lenses so far..altough I can tell it sometimes takes some time to switch the lens between the main and tele lens..you can tell because picture sudennly "clears out" while composing a shot.
I noticed different problem. When using slow motion video above 120fps resolution is horrible and focus is extremely slow.
I did experience some camera crashes while doing macro photography but continued to use the camera and phone normally without rebooting.
Same Problems, maybe even worse...
Hi,
I'm having the same problems but after the picture does not load in my gallery, it becomes just a green picture... My phone is been to the store 5 times now, i've had a new one, but i'm experiencing the same issues.
Is there a solution yet?
I have exactly the same issue with regular P30
Telephoto lens was working fine with EMUI 9.1, but since EMUI 10 any zoomed pictures results in a blurry mess, in order to use telephoto you have to switch to Pro mode AND enable RAW output, otherwise it won't work
This surely looks like a bug in the camera software

Doogee S55 camera issue

Hello,
So I have this rugged everything-proof ip68 standard android phone Doogee S55. It has not had any major impact or anything, just few casual drops on the ground (these should be nothing for such a smartphone, right?)
Anyway, out of sudden, I have noticed that the rear camera photo quality seriously deteriorated and it can not focus anymore, for example a picture of a passport has unreadable text which was perfect some time ago.
Also, you can see this random ticks on every photo shot by it. Please look at the attachment.
My question is (assuming it's real hardware damage and I cannot fix it at home)
whether it's possible to programmatically disable one of the dual rear cameras and only use a single one? (Hopefully just one camera is damaged)
Other ideas are welcome as well
