As you know, 12S Ultra has 3 camera sensors on the back.
The main sensor is IMX989, which is known as 1-inch sensor and it has best quality.
For ultra-wide and telephoto, it uses 1/2" IMX586.
When using default (Xiaomi) camera app, it uses IMX989 for wide, IMX 586 for ultra wide, telephoto, and macro.
This is normal. Nothing to be special.
But the problem starts when you're using 3rd party applications.
If application uses Android standard camera API, they will not utilize the main sensor.
Instead of a huge 1-inch IMX989, they will use IMX586 on the ultra wide.
You will get normal wide focal length (NOT ultra wide), but It will be noisier, less dynamic range, less resolution.
Maybe ultra wide sensor has two mode - full sensor readout for ultra wide, and pixel binning/cropping for macro and normal focal length.
This can be disappointment for some people, and huge minus for some nerdy professionals who using 3rd party apps like Filmic Pro.
You can test this by blocking MIDDLE lens on the back.
As far as I checked, Lightroom, Instagram, MotionCam, was not able to use Main sensor.
UPDATE : after clean installation of MIUI 13.0.7 with factory reset, problems are now fixed.

Thit is very weird, so I put it to the test.
The above apps you are saying you tried are working fine with the main sensor on mine phone.
I tried few more camera apps and they all use the main sensor too.
13.0.7 stable
I do confirm using main sensor on Lightroom.
However on lightroom it has only two camera modes, rear and front facing, and when you use the rear mode it first uses main sensor but when you are close to an object or you cover the laser sensor at the top, it automatically switches to ultrawide for macro.
version 13.0.7
Okay. I made factory reset / clean installation with MIUI 13.0.7 and its fixed now.
Maybe it was an bug on MIUI 13.0.4 or temporal error.
Thanks for checking.

yeah update note for 13.0.7 includes camera stuff, perhaps it included a fix to that problem in 13.0.4
well I'm glad it works for you now!
Have you tested motioncam / mcpro24fps? Are all sensors available, and what are the possible resolutions / framerates?
Considering a 12s Pro if the compatibility is there.
I‘ve tested MotionCam 4K at 30fps, 24fps. Only main sensor works.
But system will auto switch to macro (ultra-wide sensor) when you focus to close objects.

I came across this thread on reddit yesterday, by user Chlastek, about how low light photography could be improved on the P2. It's basically a simple process as long as you're rooted. I was skeptical initially because I have previously tried several camera apps (open camera, oneplus, etc...) and didn't quite see the purported "noticeable improvement". I checked the sample photos he provided and was surprised that they were really from the P2. I tried it out myself and the photos came out less grainy, sharper, and just better overall.

This Camera app is a great upgrade for our p2 but not a magic application... unfortunately.
After different tests, we can have good results and "correct photos" in the worst conditions :

Thank you so much for sharing this!
I've been trying out the various camera apps and ports for a while now, but results were always disappointing!
This one is absolutely awesome, and by my tests it works pretty well on daylight too.. if you zoom the pictures taken in auto mode with low light mode on you'll notice they don't have that terrible high-contrast post processing you get with the other apps
Just in case someone's having trouble finding "low light mode" (like I was), in settings - other - Use Camera2 API -> On
Hi
I installed as above but was getting the legacy warning for api2 and read the below which is from the xda thread for the snap camera app.
So not sure if it actually works better (on Lenovo p2) ?
Qte:
I'm almost certain that your phone won't support Camera2, if you get a message about being in "legacy" mode when switching to it then you should never use camera2 mode.
Edit: disregard above had a typo in the command line of build.prop. now there is no more warning about legacy more. Installed also Google camera her+ with same tweak in build prop

Yup I have been using snap cam HDR for low light..... It's superb with less noise and more details....
Hello, I am interested in buying the P40 Pro. I know that the P40 pro shoots at 12.5 MP by default, but to do this, there is some upscaling. In theory this would result in worse pictures than the Mate 30 Pro. Would it be possible to shoot at a non-scaled resolution, such as 10mp as was the default of prior Huawei flagships, and prevent the upscaling? Thanks
There is no upscaling, there's downscaling.
Main camera provides 50 MP, just devide it by 4 - and you're at 12,5 MP.
So your fears about losses caused by upscaling are quite baseless.
Picture quality is real great, just the Pro mode is close to useless, yet.
Yep, P40P uses 4-in-1 pixel binning to output 12.5MP shots from its 50MP main sensor (50/4=12.5)
I was getting terrible photos versus my previous M30P but after all these firmware updates recently, can safely say it's much better now imo.
ignore post
Gsmarena just published the review on the P40 Pro +. The image from the primary is indeed cropped. Only when users shoot at 50mp or at .85 zoom, you can see the uncropped image. This means that the image is indeed being up-scaled by around 20 percent. I don't understand why they just didn't keep it at 10.5MP to prevent this upscaling. Some Huawei phones allow you to shoot at different MPs, does this phone allowed any other image sizes besides the 12.5mp and 50mp while still maintaining aspect ratio?

^Default 12.5mp images
Shot at .85 zoom which removes the crop.
Thanks so much!
. 85x zoom is not through their ultra wide sensor?

I don't think so, in any case, when you shoot a 1x zoom at 50mp, and then 1x zoom at 12.5mp, the 12.5mp image is still cropped. About 20% of the image is cropped off, that means Huawei is doing some upscaling. I don't care about the image being cropped, the edges of most cellphone cameras are pretty much crap anyways, but I don't think they should upscale it.
Hey xda forums, not sure exactly where else I could post this as this seems like a weird software bug.
The problem is the cameras; they are not working as they should. The main lens apparently does not exist, and the cameras are glitched to the point where only the telephoto lens appears on one side (with it having the ultrawide icon and apparent 0.6x magnification when in reality it is using the telephoto lens zoomed in as normal)

By pressing the "flip cameras" button, the flipping mechanism does not work. However, the view is flipped 180° and suddenly the ultrawide lens appears! (Disguised as telephoto lens on the app and apparent 3x zoom when it actually is just the ultrawide lens working normally). I would need to manually adjust the flip camera tool to have the camera flip out to me. Also, when taking a picture the app just crashes, and no picture is taken.
The problem also exists in other applications. Snapchat only uses the wide angle lens. However, pressing the flip cameras button does trigger the flip mechanism; a problem here is that the cameras are 180° (upside down).
When using the flashlight feature from the notifications bar, the flashlight turns on and immediately the camera flips, blinding me with the flashlight facing me lol
Anybody have any suggestions on what to do?
Things i noticed before this happened was an error message "The cameras are being used by another application. Please try later". When this message started appearing, all 3 cameras were viewable in the camera app, but when flipping the camera, the app would crash if i tried to flip with the main lens. This lasted for about a week, then the camera app degraded to what I have just described
Things I have tried are:
- Use an alternative camera, such as GCam (won't open, immediately crashes)
- Safe mode
- Factory reset
- Install TWRP and Magisk, advanced wipe and download the ROM off asus website (The ROM which my phone came with as the cameras were working normally for about a month before this happened)
- Install another version of AsusCamera (internet or make backups of system/priv-apps/AsusCamera onto an SD Card and then install)
None of these seem to work. If anyone could help that would be greatly appreciated. Thank you.

Cant use my cameras
Hello everyone ! i have problems with my camera, first of all when i tried to take pictures , it freeze at blackscreen and error message: other aplication is using camera. After factory reset, same thing. Tried flash my phone , then camera opens and there is only 0.6x camera, on slefie mode it...

And the only response was to contact for repair. Is there any chance by software that this can be fixed?
I've had my Mi 10 Ultra, running the xiaomi.eu ROM, for nearly a year or so. I've found the telephoto camera quality to be very good with still subjects, but introduce any kind of motion to the scene, and it is far worse than the Motorola One Zoom I had before.
Here's an example, a slightly cropped photo from the 5x camera, tracking a moving car:

What exactly is going on here? The panel gaps between the doors as well as at the base of the A-pillar have multiplied! Likewise, there's ghosting right by the door handles! My hypothesis is that the camera takes multiple exposures and then haphazardly merges them into one. This makes the camera absolutely useless at photographing anything moving. Hell, I get better quality using stills from a video with the 5x camera than by taking an actual photograph!
So; is there any way to turn this crap off? The photo above is taken in Pro mode with manual settings, and all AI things are turned off already...
Have you tried using the "Pro" mode to set custom shutter speeds yourself?
I find it usually works well, although sometimes I need to turn HDR off to stop the multi-exposure capture if the object is moving too fast.
The attached photo was taken in Pro mode, no HDR.
I don't believe this is an exposure time issue, as parts of the car are sharp, and anyway these flaws look a lot more akin to what you'd find in a poorly stitched panorama. You can also see the pattern on the road surface looks weird, as if it was clone-brushed or something.

You should try gcam. It becomes a real photo camera... Xiaomi processing is very poor compared to Google's.
I have GCam installed, but rarely use it due to the lack of manual settings. Perhaps I'll give it a try with moving subjects, though. Thanks for the idea.
EDIT: tried it, GCam doesn't produce these exposure fusion artefacts at all.

Hi,
I was wondering if anyone else experienced this, I quite often make pictures with my front cam and the camera is such a downgrade from my 4 year old Xiaomi Mix 3! The colour balance is all off, almost like they forgot to make a profile for the front cam.
The back camera is just fine, but the front camera often looks like a $20 toy camera just because of this terrible colour balance. I can fix most of my selfies in Google Photos by using a combination of adding warmth (Colour Balance) and adding saturation which makes them look just fine.
For a phone this expensive... this shouldn't be needed. I'd say most mid-level phones even make better selfies then this.
I've tried cleaning the lens but this makes no difference, the Samsung camera app just fails to properly process the colours in the front camera's images.
Because I apparently don't value my privacy, here is a picture as taken by the Samsung camera, and the same picture after adding warmth and saturation.
The original image makes me look lifeless with the skin being very pale, like a zombie almost. It was a nice and sunny day, why do I look like I'm 10 seconds away from my death?

Anyone else with this issue? Does a modded version of the Samsung camera exist with the possibility to manually define post-processing settings? I just need to have it add more saturation and offset the colour balance
I'm searching for a solution myself, google's Gcam camera is great but I can't find a way to make it use the front camera. I'll be back if I find a way..

I've searched high and wide for a way to make another camera app the default one to get a better front camera selfie (even by disabling Samsung camera) but it seems like the cover screen and Samsung camera are intertwined and cannot be separated.
What we really need is a developer to have a look at the system framework or whatnot and see if something can be done to change the default camera, but they (developers) are a rare breed nowadays.
But on the bright side, if they ever do a remake of the movie weekend at Bernie's I'm pretty sure they'd offer you a part with photos like that..!
