Outcome: Set up your iPhone so a double-tap on the back instantly identifies any song with Shazam.

Who this is for: iPhone users who hear songs in public and want a faster way to name them.

Time required: About 2 minutes.

Quick Answer

Go to Settings → Accessibility → Touch → Back Tap, assign Shazam to Double Tap, then tap the back of your iPhone when music is playing. Your iPhone will listen and show the track without opening the app first.

What You Need First (Prerequisites)

  • iPhone 8 or newer
  • iOS 14 or later
  • Shazam available on your iPhone (built into newer iOS versions, or install from the App Store)

Step-by-Step: Turn Back Tap into a Shazam Button

  1. Open Settings on your iPhone.
  2. Tap Accessibility → Touch → Back Tap.
  3. Choose Double Tap (or Triple Tap if you prefer).
  4. Scroll down and select Shazam (or Shazam It under Shortcuts).
  5. Play any song near your phone, then double-tap the back of your iPhone near the Apple logo.
  6. Wait 1–3 seconds for the listening indicator, then read the detected song result.

Expected Result (How to Check It Worked)

  • You see Shazam activate immediately after the back tap.
  • The song title and artist appear in a small result card/notification.
  • You can do this from lock screen or while another app is open.

Common Mistakes

  • Tapping too lightly: Back Tap needs a firm, deliberate tap.
  • Using a thick case: Some rugged cases reduce tap detection.
  • Wrong action assigned: Double Tap may still be set to Screenshot or another command.
  • Microphone access denied: Shazam cannot identify music without mic permission.

Quick Troubleshooting

  1. Remove the case and test again.
  2. Re-check Back Tap assignment: Settings → Accessibility → Touch → Back Tap.
  3. Enable mic permission: Settings → Privacy & Security → Microphone (or Settings → Shazam).
  4. Restart iPhone and test once more.
  5. Update iOS: Settings → General → Software Update.

Why This Trick Is Worth Using

This feels like a hidden button on your iPhone. It is faster than opening Control Center or asking Siri, and it is perfect in cars, cafés, or parties when you want a song name fast.

Next Step

After this works, set Triple Tap to a second shortcut (like Flashlight or Screenshot) so your iPhone back taps do two useful things instead of one.
