Hi there! It seems that you're having trouble with your phone's camera. Here are some troubleshooting steps that you can try:
1. Restart your phone - This simple step can often fix any glitches that might be causing the camera to malfunction.
2. Clear the camera app's data and cache - Go to Settings > Apps > Camera > Storage, and then clear the data and cache for the camera app.
3. Check for any updates - Make sure that your phone is running the latest software updates, as this can often fix bugs and issues.
4. Check for any physical damage - If your back camera is not working, it's possible that there is physical damage to the camera. Check for any *****s or scratches on the lens or camera module.
5. Use a third-party camera app - If the built-in camera app is not working, try using a third-party camera app to see if the issue persists.
6. Factory reset - If all else fails, you may need to perform a factory reset on your phone. This will erase all data and settings, so make sure to back up your important files before doing this.
I hope these steps help you fix the camera issue on your phone. If the problem persists, you may need to bring it to a professional for repair. Good luck!
