This is what EXCELLENT camera support looks like from an OEM. Apps can access all 3 cameras through a single logical camera, and full access to all camera extensions providing native auto, HDR, bokeh, face retouching, and night mode to any dev who wants it. Great job, Samsung.

We have a comparison at twitter.com/GrapheneOS/sta. Compared to Pixels, Samsung phones have CameraX extensions and ZSL support. Pixels have proper multi-camera support via CONTROL_ZOOM_RATIO where third party apps can use the automatic switching between ultrawide, normal, telephoto.

GrapheneOS Camera device specific features:
1) Electronic Image Stabilization (EIS)
2) using ultrawide/telephoto cameras via zooming
3) image capture during video recording
4) Continuous Auto Focus (CAF)
5) Zero Shutter Lag (ZSL)
6) HDR, Night, Portrait, Face Retouch, Auto modes

Are you sure Samsung phones don’t have zoom? My S22 Ultra can go from 0.5x to 10x but not beyond in graphene camera

Nice, that means our camera app has the entire feature set on the most recent Samsung devices now. You can also enable ZSL in the advanced options but it's hard to see the difference on high end devices. It will make a difference when we add burst mode which is planned.

I think the main reason Pixels don't have ZSL support is because they provide HDR+ via the regular API since the Pixel 2. It substantially predates Camera2/CameraX extensions and is part of why they've been in no rush to implement those, since you have HDR+ on Pixels without it.

Is pixel the only phone that provides HDR through the main camera pipeline without needing an extension or requiring apps to build their own custom HDR

Possible Samsung has decent processing for the normal camera mode in other apps. You could try comparing HDR and Camera modes in low light. It should be easy to see if HDR is actually doing better by reducing noise. Normal mode could just be doing it less aggressively though.

As far as I know though, Pixels were the only devices providing great image quality via the normal camera API without needing to implement your own processing. I'm just not sure if Samsung has also addressed this now. It may not make sense to do what Pixels in 2021/2022 though.

It made sense for Pixels to do it because there was no such thing as Camera2/CameraX extensions. They did it all the way back with the Pixel 2 when they added the Pixel Visual Core, which wasn't used by Google Camera, only other apps.

Pixel 3 had that too, then Pixel 4 moved to Pixel Neural Core also providing the AOSP neural net acceleration API. They moved to simply using the Qualcomm DSP after that point which is what Google Camera did all along. It partially used Pixel Neural Core but not Visual Core.
