Hello guys

The BSG versions of the Gcam mod works really stable on our device. But there aren't optimized configs available, so the colors do need to get a little bit tweaked. In the newest versions, it's possible to save and load configs. So it would be nice if we can test some settings out. I also tried it, so you can use it as a base if you want.
Some notes about the changes:
  1. SlibP Custom lib
  2. some settings in "Additional modules settings" (much more to try out there, that's the main place to play around)
  3. activated instantaneous hdr+ enhanced (hdr+ enhanced but without loading time [ZSL], but viewfinder lags a little bit while rendering the final image because of the phone's performance)
Location to place config file: \Download\MGC.8.1.101_Configs
Used Gcam version: https://www.celsoazevedo.com/files/android/google-camera/dev-bsg/f/dl16/

There is also a thread for the A52 5G. Because both devices use the same cameras, it would be great to have one place to tinker.

Which is the apk I have to download? Why are there so many options?
Is it OK to download the fist one?

Some manufacturers only give access to the cameras for specific package names. With the Samsung ones, you should be on the safe side. You can also install different versions with different names to make tests
Wierd, the Samsung cam has way more HDR.
Try to disable "instantaneous hdr+ enhanced" and make sure hdr+ enhanced is activated. I think the google stock libs are a little bit brighter, so it should also look more like HDR. There's also a setting to change how many pictures are combined for a HDR+ image, try to increase the value. For me, too much of an HDR effect makes the image unnatural

Do the app always need to restart everytime changing lense ? And I got weird flashes on screen while trying to take a picture.

I actually agree that Samsung's pictures look better (as in more accurate to real life) when in bright conditions. GCam has slightly lower noise, but no matter what HDR mode I choose, Samsung still has better HDR and the picture looks brighter overall. GCam's night mode is much better, though.
 
First one is Samsung, second is Gcam. Samsung's colours are closer to life. Keep in mind that the houses are brightly lit, as this was taken in the morning and they're facing East. For example the flowers in the pot in the balcony of the left house look very bright and vivid IRL. (The sharpness of the shadows near the roof is likely due to clouds moving)

Both Gcam HDR+ Enhanced (7 or 15 frames doesn't do much), but first one with Google's AWB (like the previous ones), second one without. The second one looks much better, but a little over-saturated. One thing I did notice in the configs is that the AWB is set for a Sony IMX686 sensor, which I don't know if it is correct. I've been unable to find details on the sensor used in the A52. In any case, It seems that the takeaway here is to keep Google's AWB off.

Thanks for the testing. I can confirm that the brightness and colors are not quite good yet. But almost everything should be adjustable. So we still have to test a bit. The sensor I got from gsmarena.com, but is just a guess from them. By default, Pixel2 would be active, which is certainly not correct, but also worked.
Brightness correction: Additional modules settings > Lens x > Exposure compensation
saturation: Additional modules settings > Lens x > Ram Patcher > Saturation (off means it gets the variables from the lib, there are also other nice settings there to create our own lib)

When can we expect a stable optimized and stable gcam for our device. Will you please try contacting gcam developers personally? And also, please drop a link of the gcam you think to be the best one till now.

BSG is only in a Russian forum active. Arnova8G2 also makes good builds, but he only enables the app for the phones he has enough testers. We could ask him here: https://forum.xda-developers.com/t/app-arnova8g2s-google-camera-port.3862448/

So I tried Nikita's version, in terms of Color and HDR (default) it's the closest to the default camera app. I'm still playing around with the settings, so pictures to follow.

So, M51 has a similar camera setup with A52 so I thought I'd use a GCAM version from the M51 GCAM thread. Just testing Night mode and it's very clear that GCAM (right) works better. I'll edit this post to include more samples later.

Any version of GCAM I tried works better in night mode than the default camera. The problems I have is with in brightly lit scenes.

I actually tried a version of Greatness' GCAM and produced better daytime pictures, color was somewhat natural but it had better details (not noise). Unfortunately, I can't get the wide-angle lens and videos to work so I scrapped it.

I honestly don't mind the issues regarding color/hdr issues since a quick application of a vibrance filter is almost indistinguishable from the default cam. I mean it could be what the default samsung camera app is doing.

Edit: Also strange thing, low light (outdoor dusk scenario) and I get plenty of noise on GCAM compared to the default cam.
