Black Screen on POCO X4🐛

[PedroGabrielCB]

What's happening?

The Camera is working fine on most devices. However, there are a few on which it just won't work. The camera will simply try to load and stay black.

i tried add -> const device = useCameraDevices() but does work....

Reproduceable Code

<SafeAreaView style={StyleSheet.absoluteFill}>
                                <Camera
                                    style={{ flex: 1 }}
                                    torch='off'
                                    device={device}
                                    isActive={true}
                                    zoom={0}
                                    photo={true}
                                    exposure={0}
                                    ref={camera}
                                    orientation='portrait'
                                />

                            </SafeAreaView>

POCO M3 reports isZslSupported() = true, but initializing ImageCapture with CAPTURE_MODE_ZERO_SHUTTER_LAG (default behavior on 4.0.0-beta.14) will fail (results in black screen and "recoverable" error)

likely camerax bug, but maybe it's worth to workaround it

Redmi note 14 pro also has the same problem

@mrousavy do you have any suggestions on how I can fix it? I have an app in production with this problem... @

But isn't this a library bug as versusvoid put it above?

[mrousavy]

Yea, might be. I didn't investigate it yet.

Hey - I think this issue has been fixed in VisionCamera 4.0.0. 🥳

Please try V4 and let me know if you still experience this issue;

• if not, please consider 💖 sponsoring me on GitHub 💖 to support the development of VisionCamera and thank me for my time spent on fixing bugs and building new features.
• if you still see this issue, please comment and we can re-open this. But please update your native logs with the native (Xcode/Android Studio) logs from running VisionCamera V4 so I can investigate this.
