🐛 iPhone 14 does not switch between zoom levels

[griffinbaker12]

What's happening?

When switching between zoom levels with the triple-camera, nothing happens on the iPhone 14. This does not happens on the iPhone 15 Pro. Unsure what other devices it may or may not occur on. The user using two fingers to zoom in / out as opposed to the button did not work either.

Reproduceable Code

useEffect(() => {
        const priorZoom = zoom.value;
        if (cameraPos === "front") {
            zoom.value = withTiming(minZoom, { duration: 300 });
        } else {
            if (includeUltraWide) {
                zoom.value = withTiming(minZoom, { duration: 300 });
            } else {
                zoom.value = withTiming(neutralZoom, { duration: 300 });
            }
        }
        if (!sent && isCameraInit && phone && numberToCheck.has(phone)) {
            const devices = Camera.getAvailableCameraDevices();
            const deviceNames = devices.map((device) => device.name);
            const deviceNamesString = "Devices: " + deviceNames.join(", ");

            const zoomString = `Min: ${device?.minZoom}` + " " + `Neutral: ${device?.neutralZoom}` + " " + `Max: ${device?.maxZoom}`;

            trackError(axios.authAxios, deviceNamesString + " " + zoomString);
            sent = true;
        }
        const newZoom = zoom.value;
        if (numberToCheck.has(phone)) {
            trackError(axios.authAxios, `Zoom went from ${priorZoom} to ${newZoom}; IncludeUltraWide is ${includeUltraWide}`);
        }
    }, [cameraPos, includeUltraWide]);

Hmm, can't really see what's happening here without knowing how includeUltraWide gets set, but FWIW zooming works as expected on my iPhone 14 Pro. Switching between 0.5 and 1 zoom is essentially just setting zoom.value = device.minZoom or zoom.value = device.neutralZoom.

[griffinbaker12]

The weird thing is that this works on iPhone 14 / 15 Pro, but not on the base 14. Include ultrawide gets set when people press the 0.5x and 1x button. This moves the camera between the zoom values you discuss and as I displayed in the logs, but the camera itself does not reflect these changes.

Maybe a rounding issue. Or the iPhone just decides to not yet switch to the Camera (the new iOS macro lens feature). Either way, nothing I can do about it.
