Inspecting Used Phone in Nepal

1. Hardware & Display Verification (Points 1 to 5)

  • 1. TrueTone & Ambient Light Sensor: Long-press the brightness slider in Control Center to verify TrueTone is present. If missing, the screen has been replaced with a non-serialized aftermarket panel.
  • 2. Display Touch Grid Test: Drag an app icon across every millimeter of the screen to detect dead touch zones.
  • 3. Face ID / Touch ID Biometrics: Attempt enrolling your face or fingerprint in Settings. A broken Face ID indicates liquid or dropped dot projector damage.
  • 4. Camera Sensor & Focus: Test 0.5x Ultra-Wide, 1x, 3x, and 5x optical zoom under bright and low light. Listen for shaking OIS lens noise.
  • 5. Microphone & Earpiece: Record a voice memo and make a test cellular call to ensure clear two-way audio.

2. Battery & Internal Diagnostics (Points 6 to 10)

  • 6. Battery Health & BMS Warning: Check Settings → Battery → Battery Health. If it shows "Unknown Part", the BMS ribbon was altered.
  • 7. 3uTools Verification Score: Connect the device to a PC with 3uTools. Ensure the testing score is 95%+ and all serial numbers match factory records.
  • 8. Liquid Contact Indicator (LCI): Inspect the SIM tray slot with a flashlight. If the white indicator is red, the phone suffered water damage.
  • 9. Charging Port & Fast Charge: Test Type-C or Lightning cable insertion in both orientations.
  • 10. Wireless MagSafe / Qi Charging: Confirm inductive wireless charging starts immediately.

3. Security & Legal MDMS Compliance (Points 11 to 15)

  • 11. iCloud / Google Account Removal: Ensure the seller signs out completely in front of you. Never buy an iPhone with an active activation lock.
  • 12. NTA MDMS Registration: Dial *#06# and search the 15-digit IMEI on mdms.nta.gov.np to verify permanent Nepal SIM approval.
  • 13. Carrier SIM Lock: Check Settings → General → About → Carrier Lock. It must say "No SIM restrictions".
  • 14. Original Box & Purchase Invoice: Match the IMEI on the phone back/tray with the retail packaging.
  • 15. Physical Frame Stress Check: Place the phone flat on glass to ensure the titanium/aluminum chassis is not warped or bent.
