Hi guys, soon-to-be S21 Ultra (exynos) user here. Has anything changed in regards to auxiliary lenses in apps like GCam? Do the telephotos work, or still just the ultra wide? Thanks.
To my knowledge still only UW and UWW, so no telephoto lenses on GCams.... I'd be very happy if someone could correct me, though ;)
Telephoto with GCam can work...but not without effort. First, you need root. Second, you need that root access to replace a system library file with a patched one. Since a patched library file is needed, it means that with every system update, you need a new patched library. Probably not worth it for most, but if you are already rooted, could be worth a try. I don't have the Exynos model, but this file should work for the AUDA build ROMS.

Appreciate the reply @beserker15 ! Unfortunately for me I tried that method and failed miserably, so eventually I gave up and reverted to stock, relocking the bootloader.

I got another question regarding this topic, if you guys don't mind. Is there any possibility at all that Samsung might allow Auxiliary lens support in 3rd party apps, in the upcoming OneUI 4.0(?) update? Obviously I mean for Exynos. If only they could do what they did with the Snapdragon variant... All lenses being supported with the exception of the selfie cam - that would be great! Front camera in GCam is not really necessary (in my opinion), however the tele lenses would be quite useful.

So BSG GCam, ruler and scan3d versions, does detect the 3x (2.9x) telephoto... the problem is, the 2.9x button does not appear on the damn viewfinder no matter what. 😭

Try this, newly released mod (and yes still requires root).

Thanks! just tried it but doesn't seem to work on the AUG4 firmware unfortunately. And stock cam viewfinder stays completely black while this mod is enabled :(

Looks like it only works for AUF2. Apparently Samsung changes that file every firmware, so every firmware has to be re-modified. It would be cool if that developer shows how he did it, but I'm guessing the steps are not going to be user friendly since it involves modding a library.

Any hopes all these stuff and others work with newer ROMs? Is someone actively looking at it?

    After a few hours of tinkering with the settings and trying different versions, I've come to the conclusion that Wichaya's build is, at the moment, the most usable with the S21U Exynos on One UI 4.0 beta 2.

    https://www.celsoazevedo.com/files/android/google-camera/dev-wichaya/f/dl4/ - download either the Samsung Ruler or Scan3D versions (otherwise you won't have access to the Auxiliary lenses).

    Attached to this post should be a .xml file which is a configuration file, created by me, SPECIFICALLY for the Wichaya GCam 1.4 version.

    I made a few changes here and there, mostly fixing the camera IDs. Now I am pleased to say ALL cameras work. All 4 on the back and the selfie cam works too (needed a little fix).

    My .xml is quite "barebones" - I only fixed what needed to be fixed so the app doesn't crash. Although I haven't tried video modes....
    Feel free to adjust the ram patcher and other settings to your liking.




    Why is Wichaya's GCam more usable than Arnova's?

    Well, simply because there is a problem with the 3x telephoto on Arnova's version. The pictures come out very noisy, and no setting I've tried seemed to help. Also using the selfie cam caused the app to crash. So yes, right now I suggest using Wichaya's build.

    Wow its great to see some progress on the exy gcam I was beginning to think it was a bit of a lost cause with samsung not opening the apis for the tele lenses but clever members have found a work around.

    I have tried the wichaya version suggested with the .xml but when I switch to 3x or 10x it just black screens. I am not on the beta- still on android 11 (no root). Is this newfound telephoto goodness restricted to android 12 builds at the moment?
    Yes, it only works with android 12 betas.

    Hi All,

    GCAM for S21 Ultra. For Exynos, try BSG or Zoran. BSG has recently updated.

    Anybody using GCAM on S21 Ultra Exynos variant? Kindly post here which version and config file you're using.

    What's working & what are the known issues with Exynos variant?

    Do you know what are the differences between the versions? What does rules stand for and what are all the rest?
    Ya me too , i want to know what is the difference between ruler and 3d scan apks
    There are no differences, especially with Exynos for now. Samsung on the Snapdragon model allows telephoto to be used, but only with certain Samsung package names. Ruler and Scan3d are real Samsung apps that GCam is pretending to be in order to access the two telephotos.

    However, for Exynos, Samsung still doesn't allow access of the telephotos via this method, so you don't need to use the Samsung package names as all of them will work the same.
