Camera snaps the photo instantly or shows a black screen

Fix 1 — Restart your phone (resolves black screen and permissions issues in most cases). Fix 2 — Check camera permissions: Settings → Apps → Truss → Permissions → Camera → Allow. Fix 3 — Update the Truss app. Once updated, the shutter gives more time to position your check. Hold it steady and flat the moment the camera opens.
