How to Check a Used Phone Before Buying in Bangladesh – Complete Checklist

Buying a used phone in Bangladesh can be a great way to save money, but it comes with risks. Without proper checks, you could end up with a phone that has hidden issues like water damage, fake parts, or even an iCloud lock. This comprehensive checklist will help you check a used phone before buying and avoid costly mistakes.

Complete Used Phone Checking Checklist

1. Check IMEI Number

Dial *#06# on the phone and note the IMEI number. Match it with the number on the box and invoice. If they don't match, walk away [citation:5].

2. Check Battery Health

For iPhone: Settings > Battery > Battery Health. Aim for 85%+.

For Android: Use diagnostic apps like AccuBattery or dial codes (varies by brand).

3. Test Display Quality

• Check for dead pixels, burn-in, or discoloration
• For Samsung: Check for green/pink lines on AMOLED displays
• Test touch sensitivity across the entire screen
• Check brightness levels and auto-brightness

4. Test Hardware Features

• Camera: Test all lenses and flash
• Speaker: Play audio at max volume
• Microphone: Record audio and test call quality
• Buttons: Volume, power, silent/action button
• Fingerprint: Test fingerprint sensor
• Face ID: Test Face ID if available
• Wi-Fi: Connect to a Wi-Fi network
• Bluetooth: Connect to another device
• Charging Port: Test with multiple chargers
• SIM Card: Test call and data

5. Check for Water Damage

Look for the water damage indicator (LDI) inside the SIM tray. A red or pink indicator means water damage.

6. Verify Account Lock

For iPhone: Ensure "Find My iPhone" is turned off.

For Android: Ensure Google account is signed out and Factory Reset Protection (FRP) is removed.

7. Check for Repairs

• Look for loose screws, gaps, or poor frame fit
• Check if the display looks original (colors, thickness)
• Check if the back cover fits properly
• For Samsung: Check Knox status (Settings > About Phone > Status > Knox status)

8. Check Software

• Ensure the phone is not jailbroken (iOS) or rooted (Android)
• Check for any carrier lock (SIM restrictions)
• Check if the latest OS is available

9. Ask for Invoice

An original invoice with matching IMEI adds trust and value [citation:5].

10. Ask for Replacement Period

Some sellers offer a 3-7 day replacement period. If possible, ask for this to test the phone at home [citation:5].

Red Flags to Watch Out For

• Price too good to be true: Usually indicates hidden issues [citation:5].
• No invoice: Difficult to verify authenticity.
• Damaged IMEI sticker: May indicate tampering.
• Seller rushing: Not allowing time to test.
• No replacement period: Seller may be hiding issues.
• iCloud locked: Phone is unusable without password.
