Mine (SD 888) updated to Android 12 last week. Surprised to say that my 3x optical zoom appears to be working, which didn't before on 11 (only the wide and ultrawide worked). Selfie still not working (as expected). Not sure if it's actually using the optical 3x or cropping the main lens though.

Thanks for the clarification and the update about how its working, and maybe even better now!

It's too bad that Samsung limited the front facing camera. I think their phones offer the best features, but the Google Camera system offers a better camera -- in some situations. It was really great when the front camera used to work perfectly with these ports. Miss it!

I want to share my XML for S21 Snapdragon, which works on BSG 8.1 (com.samsung packages).
I set AWB for Night Sight to remove color cast, and made other minor improvements.
@beserker15's information helps me a lot. Thank you very much!
Several configs are adjusted in the file.
I find no AWB suitable for all scenes, so if you feel the white balance incorrect, just switch the GOOGLE AWB option.

Anyone want to try out the new 8.4 GCam build from the modder Shamin? It's still missing things like lib patcher but does support telephoto once you set the camera arrays. Also remember to set the stream configs to prevent freezing.

GCAM_8.4.300.18_Shamim_V17.apk

My Snapdragon S21U XML for it.


Tried BSG's ruler, tele lens doesn't work for me (exynos), i would very much appreciate it if someone could show me what version to use ? Thanks
You'll need to be on Android 12, use the Ruler one, and also whitelist I think Camera ID 50 or 52.

Installed MGC_8.1.101_A9_GV1y with BSG S21 config on my S21 FE Snapdragon (One UI 4), everything works fine except (only) the main camera freeze after few seconds.
Tried to switch the Stream Config but still...
Appreciate any input!

I can confirm Camera ID 52 is the one to use for Exynos telephoto. Thanks for the tip, mate!

Now we're in January 2022, how is the GCAM for the SD S21 (plus)? does the main lens work well? Portraits?

I'm just trying to weigh up plus vs ultra, but the ultra gets a lot more gcam attention so hoping some with experience with the s21 (or plus) can weigh in.

thanks all

Issue: Viewfinder freezes after about 3 seconds. It's unusable.

Phone: S21 Snapdragon

Apk: MGC_8.1.101_A9_GV1zfix_snap.apk

XML: I've tried them all

Any tips? I REALLY want this to work.

Since MGC_8.1.101_A9_GV1y, custom session has been divided into three modes, and previous XMLs become incompatible. You can try this:

Anyone who wants to try out newer GCam ports can follow this post. The Shamin 8.4.400 GCam works on my S21 Snapdragon.

Hi guys
my phone is S21 (Snapdragon)
Im using
MGC_8.1.101_A9_GV1zfix_ruler
with
BSG_8.1_S21_Snapdragon_V3.xml

All lenses are working fine when taking photo
but the telephto lens looks like it's only got 2X (NOT 3X)
does that still a optical zoom?
is there any ways i can get it to 3X?

Beserker15, On your post #206 a few weeks ago I downloaded and installed the Shamin 8.4 apk and your xml file on my SD S22 Ultra and they are working fine.

I wanted to share with a friend, but I notice the links no longer work, either for the apk or your xml file. Fortunately, I saved them both, but is there any reason why the links no longer work or is it something on my end?

    Is there much benefit to GCam here? Samsung's app looks good from what I've seen.

    On my Oneplus 6 it was useful, as the Oneplus app lacks panorama and Googles image processing is better.

    It depends on whether or not you like Samsung's image processing. I personally still don't though will admit they have improved over time. The biggest issue is still under lower light, where they have aggressive sharpening and noise reduction. Fine details are often a problem indoors, like hair or fur. The main camera's sensor is pretty large so that helps, but the ultra wide and telephoto sensors aren't so it's more noticeable.

    For those curious, I used Wichaya's Samsung Gcam here (3rd one): https://www.celsoazevedo.com/files/android/google-camera/f/changelog1501/

    Are these settings valid for my s21 snapdragon? Mine is not ultra...

    Tele 2.0 freezes upon selection, other lens just freeze after a few seconds on base S21 Snapdragon.

    These are my settings based on berserker15's suggestion for Ruler Gcam 6.210329.0034 build-8.1.101. Though a bit late, hope it is still useful to anyone who needs it.

    Alright guys, this BSG version with my XML attached should work well for the base S21 and S21 Plus. My cousin upgraded to an S20 which has the same camera setup so I messed around with it a little.

    Obviously the processing between the S21 and S20 is probably a little different but here's an example of stock vs BSG setup. Stock is brighter and sharper than my GCam settings but much more artificial looking.

    Also telephoto on GCam will provide more details. Stock is down sampling things to 12MP, but GCam will actually use 17MP for it.

    New Arnova GCAM 8.1 is out y'all specifically for Snapdragon models*

    No guarantees on the S20/S21 base XML since I don't have it, but should work lol.

    Hi,
    Fully working means everything works- Front Camera/Back Camera and any and all settings without crashing or freezing, that's what it means to me anyway. I know it's Samsung's fault, but why bother with Gcam ports if they don't work????
    We've gotten to a point where the builds are stable enough that nothing is crashing unless you enable a feature that isn't supported. I have no issues with going to the stock camera just for the front since I rarely ever use the front camera.

    I hope you know that not everything in stock camera "works" either. You can't manually choose the 3x and 10x when there's somewhat low light, or if the camera claims that you are too close to the subject. Oh, and not to mention that the stock camera still looks way worse on the auxiliary lenses.

    This picture is impossible to get via stock because stock will always switch away from the 10x and instead use the 3x cropped in because it's "too close".
    PXL_20210709_160555525.jpg

    This here is the limit to what the camera will still allow the 10x to be used before switching to the 3x:
    20210707_153235.jpg
    which looks horrible still compared to GCam:
    PXL_20210707_223332516.jpg
    but even worse since that's not the minimum focus distance the 10x can achieve, which is this with GCam:
    PXL_20210707_150019494.jpg

    So yeah, in summary just using stock is fine, except I refuse to accept crappier quality and weird software limitations when I know I can get better pictures with something else.

    Is there a way to tweak the Wichiya gcam xml so that portrait mode shows by default instead of camera? Portrait mode autofocus works well, doesn't freeze, and there is far less noise than ZGcam.

    I looked into the XML keys but don't have an understanding of what keys to modify or add.
    Curious regarding the same thing, I wish I knew a little more about the inner tuning of the XML. Great job getting it where it already is. Unfortunately, I still get some studdering with my S21 Ultra in mid-light sceneries. I'm keeping a good eye on the GCam Hub for updates, in hopes something will come around!

    Don't worry guys, Arnova's latest will be released soon. I can confirm that the 4 rear cameras work great on Snapdragon S21 Ultra and is also the first GCam with video working on the telephoto (albeit at 1080p instead of 4K). However the awesome thing about the video is you can set the zoom to be greater than 20x unlike stock. Here's a couple of samples from the 10x and 3x with that unreleased GCam.
