Can you give a hint where to switch into wide angle? The manual tells about an icon where to switch between the camera IDs, but I'm only able to switch between front and (standard) back camera...

Hi great news! Nikita's newest gcam build 2.0 is capable of 12MP (4624x2604) pictures and also 1080P video in wide angle camera mode. I use standard config file advertised in this thread for over a month now (HDR+ 15 frames). Audio bitrate 192KB/s. Really happy :)
[Xiaomi Poco X3 NFC Themes, Apps, and Mods] Vihru:
what makes you choose Nikitas gcam?
[Xiaomi Poco X3 NFC Themes, Apps, and Mods] rudix78:
I use custom rom so no stock xiaomi camera app. I found out about Nikit'a gcam in this thread, I tested it and all lenses work in picture as well as in video mode and now they work also in 12/16MP resolution. So I recon it's good enough for my needs.
[Xiaomi Poco X3 NFC Themes, Apps, and Mods] Vihru:
macro also? ultrawide?
[Xiaomi Poco X3 NFC Themes, Apps, and Mods] rudix78:

Good afternoon mates.

With so many modifications I am a bit lost, and I would like to use a GCAM that is fine, I don't need it to do crazy things, just that everything works more or less well.

Which one can I use?

Thank you.
[Xiaomi Poco X3 NFC Themes, Apps, and Mods] PabianPL:
Use the newest gcam from Nikita
[Xiaomi Poco X3 NFC Themes, Apps, and Mods] just Nob:
Hi @rudix7,

sounds great! I'm going to switch to a custom ROM soon, so I'm looking for a stock cam replacement in advance. :giggle:

Do you know something about support of depth sensor lense by Nikita's gcam? As far I know, this is used for bokeh effect by stock cam when taking portrait pics, and I like them very well (not for every situation / kind of photography, but sometimes it's a nice looking effect)...
[Xiaomi Poco X3 NFC Themes, Apps, and Mods] just Nob:
Sorry, some more questions... - maybe some silly ones...:

...as well as...

I guess you both are talking about Nikita's GCam NGCam sersion 7.4.104-v2.0 hosted here at GCamHub?

What is the difference between the the "eng" and "snap" version - probably "eng" is for "english" and marks the latest stable (english) version, whereas "snap" is the latest snapshot (i.e. a newer alpha or beta one)?

It seems that these are versions working on all (or at least most) devices - correct?

Are the Aux(iliary) Cameras Enabler or 48MP Unlocker needed for the Poco X3?
[Xiaomi Poco X3 NFC Themes, Apps, and Mods] rudix78:
My understanding is that eng means standard gcam package whereas snap is the same but clone under different package name. It gives you option to have different xls files for different needs or test other gcams while still Nikita gcam. I use eng version with standard package name, but sometimes install clones from other developers to check their work.
[Xiaomi Poco X3 NFC Themes, Apps, and Mods] just Nob:
Unfortunately I must say that I'm not that happy up to now. :(

I'm still on stock MIUI Global 12.0.4 stable, rooted with Magisk. For being sure not to have any interferences with other modules, I disabled all of them (excluding BusyBox for Android NDK, which was still active) for test purposes.

I installed NGCam_7.4.104-v2.0_eng.apk and loaded the proposed Ngcam 1.8 POCOX3 v3.xml configuration. At first, I was happy about the three icons for choosing the standard, wide angle or macro lense, appearing at the bottom of the picture preview by loading the configuration file.

All lenses work in principal, but both wide angle and macro lense have a coloration / color scheme problem when taking a picture, regardless of the mode (standard, portrait...), whereas the standard lense works always fine.

The problem doesn't come up when taking a video, regardless of the chosen lense - videos do always have correct colors.

Here are some examples:

Standard lense - works fine as expected:

Wide angle lense - always colored in a violet flavor:

Macro lense - always colored in a flavor missing green:

Is anyone else having that problem?

Have I chosen the wrong xml configuration file?

Do I have to install any patch / fix?

Any other ideas?

Try this xml, you'll see the difference:
[Xiaomi Poco X3 NFC Themes, Apps, and Mods] Lucid Interval:
I'm using newest Ngcam with asus library xml and I decided to give this 'instantaneous HDR mode' a try. So far I really don't see much of a difference between HDR+enhanced and this mode (example below) and it's so much faster. It's only slightly less detailed, seems negligible.

Instantaneous HDR

HDR+enhanced

Most of these cams / configurations seem to have issues when using the front-facing can for me. Some only made green images (although the preview was fine), others simply crash often.

[Xiaomi Poco X3 NFC Themes, Apps, and Mods] rudix78:
You are right all gcams have shortcomings and things that doesn't work. You need to find one that serves most of your requirements and constantly look for new versions from different devs. Also some gcsms are not optimised for A11 yet. I guess RR runs on A11.

My quick review:

Main camera picture resolution 16.1MP 4x3 (3472x4624) but only 8.3MP at 16x9 (2160x3840).

Front camera works at 5.0MP and 2.1MP respectively but produces bluish colour. So not usable at this stage.

Cannot access gallery directly from gcam (no support for third party gallery).

No support for wide and macro cameras.

No video stabilisation as far as I can see.

No manual exposure/ISO settings :(
[Xiaomi Poco X3 NFC Themes, Apps, and Mods] surferbyter:

Regarding video recording. I noticed that you used config recommended in this thread that is: settings/advanced/stream config/video stream config - VIDEO EIS. With this settings I've got zoomed in field of view, comparing to picture camera. Please switch between camera and video back and forth and let me know if it's the same for you. When in video stream config I choose - MIUI BACK both camera (pictures) and video have the same field of view.
[Xiaomi Poco X3 NFC Themes, Apps, and Mods] vanpoko:
Corrected with Video EIS Pro, it works better and doesn't affect the slow motion. Video stabilization keeps being very good.
[Xiaomi Poco X3 NFC Themes, Apps, and Mods] Picard20:
If picture and video have the same exact field of view, that means image stabilization isnt on.

But I agree, VIDEO EIS cropped way too much (but its more stable as a result), so the sweet spot seems to be VIDEO EIS Pro that vanpoko suggested.

Thanx for the EIS Pro tip.

Good morning, I'm from Brazil and I live testing GCAM ... I've been helped a lot here in some posts, today I come here to make available (in my opinion) the best gcam for Poco X3 that I found. I edited the XML to my liking, left it in tune for my "use". I left the ultra wide running too, to change it just rotate the cameras. The application is PixelCam X ... I'll leave the links for you to download. I would like opinions on what they found, but it is a camera for photos ok, I do not guarantee stability in filming, etc ...

XML should be inserted into: storage/PixelCam /X/

However the resolution of the photos is limited to 12mp (instead of 16) and also i can't find the ultra wide camera.
[Xiaomi Poco X3 NFC Themes, Apps, and Mods] dihzinhow:
Really it only uses 12mp, I compared it with some gcam that support 16mp and I didn't notice much difference in details. Ultra wide is in the rotation cycles (where you switch to the front / rear camera) - you turn once, go to the front, turn again go to the ultra wide, turn again, go to the front, turn again, go back to normal .
[Xiaomi Poco X3 NFC Themes, Apps, and Mods] NotChinaMobiles:
Okay, seeing u guys struggling to find a all working gcam makes me sad so i wanna share with u what i found.

First, the xml is not by me, its from an indian youtuber wich i cant find atm.

What works? All - also the video front cam.

Mpx dont matter so i dont care about.

What are the Higlights? Nightsight for Front cam and Wideangle Lens - both gave me impressive results and outperform my wifes Mi10 by alot.

uma Is the slow motion of your stock camera working?
[Xiaomi Poco X3 NFC Themes, Apps, and Mods] rudix78:
Thanks for sharing. As for still images I prefer Ngcam as it produces higher resolution pictures in 18/9 ratio and has more options to play with. So I was more interested in it's video recording performance.

Although I couldn't get 4K vidos (despite toggling ultra-high resolution video) EIS works in 1080P. I compared it with latest Arnova's build and I see much better stabilisation (to be honest in my opinion stabilisation doesn't work at all in newest Arnova gcam despite cropping videos in both Video EIS and Video EIS modes). So big + for Urnyx regarding video stablilisation in 1080P. FYI I run custom ROM (and my phone may not have all camera optimisations stock ROM has and this may be the reason stabilisation does not work for me on Arnova's gcam 8).

PS. I think something is messed up and 4K video works on wide angle camera solely.
[Xiaomi Poco X3 NFC Themes, Apps, and Mods] InContext:
Every time I press something different on the app, it 'reflashes' the whole app, like it closes it and opens it completely again. I can see the wallpaper as it's doing it.

Say if I scroll over to nightsight, it's on 1x, I press 2x and it does the flash thing, and takes me back to 'camera' but it's on 2x, then I have to scroll to nightsight again.

If I press 0.6x it crashes completely.

Why does 'try night sight' keep coming up, annoying af. I've turned off all the hint type options.

[Xiaomi Poco X3 NFC Themes, Apps, and Mods] Firnefex:
For me on Xiaomi.eu 12.0.7.0:

- Arnova8.1 is stable, has the cleanest UI, but there is no ultra-wide, and pictures are too white

- Guernica7.5 crashes on Selfie, but has the most options and more natural colors

- Nikita doesn't work and crashes all the time...

- trCamera_Xmas also crashed 2 times, so I didn't try further.

I've tried several xml's for these mods, even with other apk's, there never was a big wow effect.

Despite Guernica with sharpness 2.0 has a little advantage over stock, I didn't feel that much of a difference.

Also Gcam works better in complete darkness, but who cares?

Overall none of these GCams could really compete with the stock camera (at least in every possible situation inside my house), which produces the most realistic colors and no overexposed lights from the christmas tree.
