Daniel MicayIt has support for zoom-based switching between cameras on devices with support for that via the Camera2 API such as Pixels (Pixel 4 and later) and VERY recent Samsung phones (perhaps only the most recent generation). It shows a virtual zoom range and automatically switches to ultrawide and telephoto cameras. On the Pixel 6 Pro and Pixel 7 Pro, it works exactly like Google Camera where the OS adjusts the zoom level it switches to 4x telephoto based on available light since it's worse at handling low light.
It's theoretically possible to implement manual multi-camera switching without direct CameraX support for it but it would be complex and the UI would likely be confusing / vague due to lack of device support for the multi-camera APIs, since if they had that it would already be working via zoom.
EIS support also depends on the device providing it via Camera2 which is available on most decent devices. Experimental ZSL toggle improving latency mode is similar and while Pixels don't have the required functionality yet, Samsung provides it.
Our app also has modes for HDR, Night, Portrait, Face Retouch and Auto on an increasing number of phones with CameraX extension support. This is still missing on Pixels but is available on Samsung phones from the past couple years and predated Samsung supporting zoom-based multi-camera even though that feature was around much earlier.
We're open to help working on translations but the first step is properly splitting out the strings as a prerequisite to starting that and we haven't gotten help from contributors so no progress is being made. We don't have time to work on it ourselves.
