How to Check for Errors from your New iPhone

1. Check for Setup or Activation Issues

Make sure your iPhone activates properly with your Apple ID. If you see errors like “Unable to Activate” or “SIM not supported”, restart your phone and try again.

2. Run an iPhone Diagnostic Test

Apple has a built-in diagnostics tool:

Open Safari on your iPhone. Go to 👉 https://diagnostics.apple.com. Sign in with your Apple ID. Follow instructions to run Apple Diagnostics (it checks for hardware issues like battery, sensors, or display problems).

3. Check for Software Errors

Go to Settings > General > Software Update → install the latest iOS. If apps keep crashing, check for app updates in the App Store.

4. Test Key Hardware Functions

Screen & Touch → Try swiping, tapping, zooming. Speakers & Microphone → Play music and record a voice memo. Cameras → Open Camera, test photo & video (front & back). Battery Health → Settings > Battery > Battery Health & Charging. Face ID / Touch ID → Set it up and confirm it unlocks smoothly.

5. Check for Error Logs

Go to Settings > Privacy & Security > Analytics & Improvements > Analytics Data. If you see repeated crash logs for the same app/system process, something may be wrong.

6. Run Apple Support App Test (Optional)

Download Apple Support app from the App Store. Tap Get Support > iPhone > Run Diagnostics. This will run checks and send results to Apple if needed.

If you find any issues, contact Apple Support or visit an Apple Authorized Service Provider while your iPhone is still under warranty.
