🐛 Troubleshooting

❌ App Restarts After Taking a Photo

• Ensure you're using MediaStore API instead of FileProvider.
• Use cameraLauncher instead of startActivityForResult().

❌ Images Not Displaying

• Ensure READ_EXTERNAL_STORAGE permission is granted.
• Check if images are being saved to /storage/emulated/0/Pictures/.

❌ Camera Permission Not Triggering Camera

• Ensure requestPermissionLauncher handles CAMERA permission properly.
• After permission is granted, open the camera immediately without requiring the user to click again.
