Is there a way to change the default camera to the 12MP one? - Xiaomi Mi A2 / 6X Questions & Answers

Is it possible to use the low-light camera as the default one so 3rd parties like GCam can work with it?

Just use night view or manual but why you want to do that? More megapixel won't mean better camera just larger image

It actually means brighter photo in low light. The megapixel count might be higher, but it uses pixel binning to give 5 MP output, but a better low light image.
I think the reputed devs owning MI A2 here should develop some patches or modules to use second camera with GCam.
- Mi A1 has got it done with the telephoto lens
- One plus 5 got it with almost similar config as MI A2. Its secondary lens is low light, and uses same pixel binning like MI A2.
All we can do is hope that some dev researches a bit on this and gets this working on our device too. I'm very sure that its possible since GCam has made its way to triple lens switching already.

Photo quality

Say "cheese", then rate this thread to express how photos taken with the Google Pixel 2 come out. A higher rating indicates that photos offer rich color (without over-saturating), sharp detail (with all subjects in-focus), and appropriate exposure (with even lighting).
Then, drop a comment if you have anything to add!
Not taken by the "average consumer" but I have to admit that these picks are AMAZING! Cant wait to have my 2XL in hand to test it out! https://9to5google.com/2017/10/07/google-pixel-2-photos-videos-samples-gallery/

I haven't taken more than a few photos, but oh my lord this camera is absolutely awesome. Depth of field trick is snazzy and works perfectly 99% of the time. Color accuracy on photos is mind-blowing.

Took some sample pictures with Pixel 1 and Pixel 2, compared images on PC, they look identical but some are better on Pixel 1. Pixel 2 colors are more saturated and there is no flare....
I have been comparing the photos from the Pixel 2 to the iPhone 8 Plus if anyone is interested ?
Daylight and Night time
Took pictures today after dusk, same thing. Most images look identical to Pixel 1, but when I zoom in I can see that lens on Pixel 1 is a little bit sharper with less noise.
Edit: also noticed that automatic white balancing is off sometimes. Pixel 1 gets it right while Pixel 2 doesn't.
But all negatives are relatively small, I wouldn't say one is better then another
I don't find the camera miles better than previous phones I've owned (S7, S8, 5s pixel port etc). But it's capable, fast, a good allrounder and DOF mode is okay for a single lens construction. Hdr+ is a joy and considered, that Google don't yet utilize the new chip empowering this function it's FAST.

I have been able to take amazing pictures with the N5,N5X,N6P and now with the Pixel 2.
HDR+ does a great job in all these phones I owned.
The main quality difference between the N5 and the latest 3 I mentioned, are the megapixels. (But HDR+ quality was still solid in the old 5).
They main difference between the 5X/6P and the Pixel 2 is the speed to take photos, launch the camera, focus and process the HDR+ but the quality is really close.
I've decided to stick with HDR+ enhanced (which is similar to the old HDR+ in the Nexus) to minimise the risk of getting unfocused areas that sometimes with the HDR+ are not so detailed. So I'm sacrificing speed to capture photos to try to get always a perfect HDR+ shot.

I don't know because I stopped using cameras for my trips, since I got a Nexus 5 with HDR+ and before that I mostly used the typical compact Sony cyber shot with Carl Zeiss lense.
And I only regret to use smartphone as main camera when I switched from the N5 to Z5 Compact and went to Paris and took ugly photos. Specially nightly photos and closeup photos. This is the main reason I sold that phone after 6 months and went for the 5X.
Probably you can get better details with those cameras you mention. But there are some key features in HDR+ (this is all post processing) that do a lot of magic:
- Focus in most of the areas. (You can focus on a person's face and still capture the details behind a window that points to the street / or the clouds in the sky/ or other faces; as if you had focused directly on that window or clouds).
- More dark skies at night. The night photos look amazing. Nightly skies try to be converted to a more solid dark colour.
- Same good quality with sunny photos that have a lot of sunlight or sun rays and you can't see well trough the camera app when taking the photo because of the high brightness. After HDR+ you could have a good result more opaque.
Other things I like from the latest Google phones cameras:
- Panoramas. Sometimes I take a panorama with just 1 captured image, because of the increased FoV to fit a building. And sometimes you need to take more than 1 because the building still doesn't fit.
- Capture photos when walking: In previous HDR+ Nexus cameras when you press the shutter, camera starts capturing and you can have blurry photos if you were moving. In The Pixel 2 when I press the shutter of the camera (also walking and with HDR+ enhanced) phone camera blocks and take some time to capture to maximize the possibility of a crisp shot. (And if you press the shutter and starts shaking the camera it won't capture till you stop shaking)
So I'm taking photos when I don't have time to stop now.
- Minimum focus distance: I love close-ups / macro shots and the latest Google phones had a good minimum focus distance and mixed with HDR+ the result is amazing.
(The Z5 Compact I owned used to have a wide angle but terrible minimum focus distance I hate this).
What I don't really care is the new portrait mode. You get 2 photos when using it. With blurry unfocused areas and the original with no blur. I think this is only useful for CV photos or some close-ups or special cases. There is a lot of people that loves this feature. I personally prefer the photo that contains more data for 99% of my captures.

Absolutely love the camera on my Pixel 2. Below are some examples shot really quickly from The Shard in London.
I had the iPhone 8 plus briefly and although similar, I'd probably say the Pixel 2 is a bit better, I also think the portrait mode is insanely good considering it only has one camera! :highfive:

absolutely not.
however, the pixel takes decent pictures completely automatically while you can completely mess up a picture on a mid range a mirrorless camera if you don't know how to use the settings - and the fully automatic mode of the mirrorless cameras tend not to be actually as good as the pixel
(technically, the pixel is also a mirrorless camera btw - just that the sensor and lens are tiny, get less light and aren't as sharp, basically - but they have much better automatic processing)

I had Canon G5 ($500 compact camera) and gave it away with a purchase of Pixel 1. I think P1 pictures are much better.

Google Camera Mod for P20 Pro

Hello @Arnova8G2,
I saw your work with the Google Camera Mod for various phones and I just want to say impressive work! I am using the Huawei P20 Pro and absolutely hates the Front Camera functionality. Tried to download your file to use on my phone but was unable to do so. When I try downloading it is says there as a problem parsing the package. Do you by any chance know if it would work with the P20 Pro? Any help is greatly appreciated. Thank you very much in advance.
Dear @Arnova8G2 & @miniuser123,
I had S8 and you do fantastic job porting Pixel Xl 2 camera to all SD845 phones. And some other make port for LGV30 dual camera - rear camera and second wide angle camera.
Please make Pixel Xl 2 camera port for Huawei P20 Pro for 40MP, 10MP and camera zoom 3x, 5x.

It makes absolutely no sense to do 40MP. It's the inferior mode, and processing overhead would be insane for HDR, even with full optimisation (which you'll never see on a port). It wouldn't work.
Only 10MP makes sense.
5x is a hybrid zoom. You'd need the Huawei software. Google Camera currently has no such functionality. Not that it supports any optical zoom (3x) by default either.
You can perhaps hope for 10MP with working HDR+ and front camera. Anything else? I'd say it's completely unrealistic / unnecessary.
After the software updates, the only thing I'd really see Google Camera as being useful for is the front camera and / or for AOSP when that becomes stable on the P20 Pro. But by then, a working port of Huawei Camera on the P20/Pro is quite likely - or at least more likely, and certainly more desirable than a Google Camera port.

Yes, I am just hoping for the Front Camera to have the same Portrait Mode as the Google Camera as the Beauty Mode post-processing is through the roof even with it turned to zero. I am just hoping to use the Front Camera I have on the P20 to achieve the same Portrait result as I did from the Pixel 2 XL. Everything else about the P20 camera I can live with. Thank you.

Yes! Finally someone who has the same struggle as I have!
P20 pro is a pretty expensive phone and I am beginning to feel disappointed with the less than stellar quality of its front camera.
I know that its a fixed focus lens on the front but how come Gogle Pixel was able to implement a sharp shooter front camera with a fixed focus? To think that it has 24 Megapixels?!?! Such a scam

I don't think you understand what scam means.
Also, whilst not ideal, I suggest you learn how to work with fixed focus. You will not get bad results with it if you do, now that 'beauty' is in check.

Hi @mudnightoil,
sorry for the rather strong term that I used. But yes, I have been trying to learn some workarounds with a fixed focus front camera. It's just that, it's difficult to adjust because I was just so used to autofocus front cameras like Asus Selfie. I just feel like the 24 megapixel camera of the p20 pro is a wasted potential.
Another argument that I have is with Google Pixel's 8 mp fixed focus lens producing more vivid and sharper selfies than P20 pro's 24 mp.
Both the background and the foreground are sharp. Dynamic range is better! I mean come on! I really hope it could be fixed via software update very soon!

Same issue here ...the rear cameras are great ..but the front camera beautification is just too agressive even when set to zero . A google camera mod with HDR+ in just 10mp for rear camera and portrait enabled on both the front and rear will be really helpful .

That's not a GCam port, that's to install the P20 Pro Camera software on a non-pro P20.
So far as I'm aware you'll need the libs to get it to work properly.
Tbh the pro has a monster camera set up.
The 40mp is more for landscape pics, the 10 for point and shoot.
the selfie cam has been great for me so far.
But then I've only had it since 11am 24th may so I'm sure I'll find some issues.
The rear cameras are great and on average they take better pictures than my Pixel 2. I also end up with pictures that I just otherwise would never have been able to capture with another cameraphone. There are some downsides though where I would love to use a hypothetical GCam port. Outdoor photography is a chore thanks to the auto "greenery" AI thing that cranks the saturation. The 10 MP auto mode also oversharpens like crazy. Pro mode is sometimes useful, but you lose things like HDR or aperture simulation which are lame tradeoffs.
The biggest issue for me though is the front camera, which is completely unusable thanks to the beauty mode that can't actually be fully disabled. I'm using Retrica right now which works pretty well but you lose the nice aperture/bokeh simulation of the P20 camera app. Small price to pay for a human looking face, but anyway that's mainly why I'm hoping for a GCam port.
I am very interested in development. Maybe it's possible.

The 10MP mode is superior in almost any setting. Hence why it's the default mode. That the 40MP mode is even exposed is mainly for marketing reasons.

That's not the case at all from my experience comparing 10 vs 40 vs 3x zoom in various situations.
In low light, 40mp is poor, but in well lit places, 40mp is far more detailed, less over-sharpened, and significantly nicer overall.
It's generally less processed, and HDR etc doesn't seem to be enabled on it, but it's certainly not inferior to 10mp in general, but is occasionally.
If you want to do any post processing, the 40mp is probably better in general... though I guess few would want to do this!

how can redmi note 7 have 48mp camera but snapdragon 660 only can afford until 25mp

I wanna ask how can redmi note 7 have 48mp camera but snapdragon 660 only can afford until 25mp
It's fake 48mp which made by ai algorithm, you need to wait for pro version if you want the real 48mp.
But redmi 7 pro maybe use snapdragon 710 and still snapdragon 710 cant afford for 48mp

What the Samsung's sensor do, it's they stick 4 tiny pixels into one big pixel, for brightness in the images, actually there is a 12mpx camera but the result it's from a 48mpx resolution. You can look into it.
It's NOT a fake 48 mp camera. Let me explain,
The camera has physical 48million pixels , same as Sony imx586(used in redmi note 7 pro).
But let's see what's the catch about 12mp thing.
So as i said earlier, SAMSUNG GM1 SENSOR(used in redmi note 7) actually has physical 48million pixels.
What it does is, it treats every 4 pixels as 1 bigger one. So that means when we have 48(million) pixels. And 4 pixels will be bind together and made 1.
Result is we get 12(million) pixels in resulting pic.
Now this is done to get more bright images, so that each Pixel of image can get more light.

48MP Camera on Redmi Note 7 explained by C4ETech
it's the same trick used with Xiaomi's latest 20MP or 24MP front facing sensors. it combines 4 pixels into 1 bigger pixel (this is called pixel binning). for example: if you install a custom ROM on the Poco (which has a 20MP front facing camera), it will register as only 5MP, but in reality, you actually capture 20MP, combined into a 5MP picture, this tech helps with low light and creating brighter images.
so basically: the SoC registers the sensor as 12MP, but its truly 48MP.

1) 25mp is for single camera not for dual
2)It can't, the camera is just an interpolated version of a 12mp sensor thats all. Its just an edit

yah i also think like you but some youtuber in my country they explanted that redmi note 7 would has a small cache to process images

I don't think this is fully true
Poco video selfie is just so dark like no native binning at all. This is different to the big pixel like on mi5.

I don't think there is a phone currently that does pixel binning in video, now it's just done in photo.
Binning adds the the brightness of 4 pixels and merge then into a bigger number.
(example: 4 pixels have brightness values of 3,4,5,3 the binned number is 15(3+4+5+3), meaning that pixel is brighter, if it were averaged, it would have had a value of 3.75 ((3+4+5+3)/4) and it's not bigger than the original pixels values, meaning no brightness improvement)
(the real process of binning pixels is actually much more complicated, and simple addition may not be done)
While in video the brightness of individual is averaged(not binned) with neighbouring pixels to make 30 1080p (2.1 Mp) photos per second.
If someone understands the process of real pixel binning, then correct me if i am wrong.

If someone understands the process of real pixel binning, then correct me if i am wrong.

Lg v30 V35 g7 v40 have super bright mode video, 2x2 4in1 pixel binning in video (4K becoming full HD), + there's adaptive fps for lowlight
HTC has multiframe subsampling processing for lowlight noiseless video
Sony has dual camera sensor fusion (normal & bw) for super high iso lowlight video
No, you're wrong
Binning isn't always about 1+2+3+4= 10, it can also be like 1+2+3+4=10 :4= 2.5 (PureView) or 1+4+4+5=4 or 1+2+3+4=1/2/3/4 (real time hdr)
And there's no averaging in lower resolution normal video processing, it's not even using all the pixels of the full sensor. That's why most flagship use 12mp 4:3 (video is cropped 16:9 8mp 4k), no wasted resolution

I did say: "the real process of binning pixels is actually much more complicated, and simple addition may not be done" i was simplifying the technical stuff. Pixel binning is also done by averaging values, though not benefiting brightness but noise reduction.
In video the camera actually sends full frame raw data to the isp, which manipulates the raw sensor data by cropping and subsampling (technically the same as binning by averaging) and then dumping that data on flash memory as a video format.
Most modern phones use subsampling by averaging because it reduces noise.
Many phones have issues with noise while filming in 4k in low light condition because the noise filtering applied to videos must be fast and efficient, where as photo noise filtering is done with much more processing.
The LG super bright video mode is most likely some kind of software trickery that forces 1080p resolution because subsampling reduces noise, and does one of two things either increase iso or increase brightness/contrast in post processing.

I believe subsampling =/= averaging
That's why lowlight video from 40mp Huawei mate 20 pro sucks so bad
Lg bright mode is a real time processing, 15-24fps, ev +1 stop (higher than max iso on auto /manual mode), 1/4 max resolution,
I've been wanting to ask this question since, Xiaomi lies a lot when it comes to phone specs. Well, it's cheap, so we can't complain.

Is it possible to use the 20 mp sensor with Google Camera?

Yes, i have camera2api enabled and the quality of the 12 mp sensor is stunning. But... i want to take adventages from the second sensor. I've tried some fu24 mods but all crashes right away you start the app.
Thanks in advance.
20mp is for the depth sensor and Mi A2 doesn't click pictures of 20mp. (i think so).

I'm not sure about this. In the Mi A2 page says that it uses the 12mp sensor to take daytime photos, and the 20mp to take low light photos. I think that the stock camera app can do this change automatically. But I'm not sure if GCAM app can do this too.
Probably GCAM is using the 12mp to every situation, and doing all the work into software, even to manage the portrait (focus) effect, ignoring the 20mp sensor.
It is possible but you will have only 5Mpx, because it's quadra bayer something technology
On latest pixel experience caf I can switch to low night lens (latest arnova gcam). On stock it doesn't work

Wow, do you use a magisk module or something? or only pixel experience?
It takes 20 mp photos or 5 mp like someone suggested?
Could you share samples?
Sorry, a lot of questions, i know, but i'm trying to see if it's worthy install pixel experience for the second lens, or with camera2api enabled on stock i'm fine.

In options you can enable second camera.
Pictures are 5mpx in size. There is some pink tint, but not much. Quality is same as using 12mpx camera. I will post samples later.

Only magisk module I have is pixel3 gcam enabler for mi a2(I think I found this on xda). GCam_6.1.021_Advanced_V1.4.032219.1950.apk
Quality is not too low it is almost same with 12mp. Color correction is more accurate. It works for only photo and portrait (video,night sight tested others untested)
Edit: for samples I don't have stable interneth connection for now
Edit2: I found a way to use low light lens with night sight. After switching to low light lens just close your camera with your hand. on bottom try night sight will appear if you click that you can use it with night sight

Rom is worthy , better performance than stock Android one also have some extra features such as fast charging,arcore
share a sample photos guys with comparison of 12 mp VS 20 mp of gcam ... so others can know & helpful for us
Here are the samples

This is working great...the color processing is as expected from Gcam.
post some comparison shots, would be great to see the difference

Would love to see too
i made a few pictures with both apps. just my summary:
1.xiaomi has better dynamic range, or in other words, brighter shadow.
2.xiaomi's color is more accurate. gcam has a cold color tone to it.
3.gcam is somewhat shaper without the weird sharpening effect.
4.gcam removes fringing a lot better, on edge of big color shift of two objects (tree vs sky, black bottle vs white background), it has a clear boundary, xiaomi is more murky-looking.
5.overall gcam exposure is a tad lower than xiaomi's.
6.gcam only has 1x and 2x, no wide angle. for potrait, it has 1x and 1.3x, picture seems to have very bad exposure.
7.all pictures were taken indoors, so i haven't compared the outdoor pictures.
i wouldn't switch.

Always find mi cam exposure half a stop overexposure....even more so at highlighted area that hdr fail to control sometime. And their awb is always wrong under warmer lighting condition. But there are more Gcam mod to try out. But I do notice...some Gcam mod had that weird green tint to white color background.
Anyone came across a better Gcam port...do share
Tones to pick from the link below.

Description about each Google Camera Port developer and links to their download pages.

This is working but I don't see much advantage in it tbh
I agree after testing out a few mode...the color are more contrasty using Gcam. But only so marginally ....
Can anyone post comparison shots ?

1. Better HDR ? That's strange. However if it's just that the shadows are underexposed with gcam, that's somethign you can fix in the settings. Gcam is tuned for the imx363, obviously it's going to need some tweaks to work well on the gn2.
2. Make sure you have AWB on.
5. Again, exposure can be tweaked. Right now BSG has one of the most versatile, easily tweakable mods.
6. This you need to inform the devs about. Gcam is only acessing one sensor here, and digitally cropping 2x. But you can probably access both the 0.5 and 5x lenses as well. If the devs can make Sabre work on them this will lead to much better detail on both these lenses.
If you guys want test this new Greatness GCAM version:
https://www.celsoazevedo.com/files/android/google-camera/dev-greatness/f/dl2/
The Officially Supported Device is divided into two categories:
Category 1: OnePlus 2020 Phones with Everything Working
Category 2: OnePlus 2019, Oneplus 2021, Oppo Find X2 Pro and Mi 11 Ultra with only one video related feature missing.

unfortunately there's no Auxiliary lens support.
Be aware that next Wichaya version will work perfectly.
Been using for weeks and it's great.

Did Wichaya release next version? I see his GCAM is outdated and last version is a 7.3 from december.

How do you know he is going to release a fully working GCAM? source?
What's the main difference between Gcam and the official camera app?

You are trying a GCAM posted 1 month ago and that version is a cstark version from january:
https://www.celsoazevedo.com/files/android/google-camera/dev-cstark27/
Mi 11 Ultra was released not long time ago and GCAM development is poor. You need try newer GCAM versions to find a better one, not OP link from a clickbait website. Check always latest releases here:
https://www.celsoazevedo.com/files/android/google-camera/
Pixel on the left and stock Xiaomi on the right, no settings altered
