A used Android phone can be excellent value, but buyers should verify much more than appearance. Account locks, cloned identifiers, unpaid finance and hidden repairs can surface after payment.

Verify the IMEI

Display IMEI 1 and IMEI 2, compare them with the box and invoice and use available registry or operator checks.

Verify the seller

Ask for ownership evidence, purchase history and repair history.

Remove Google and manufacturer accounts

The seller should remove accounts before reset. This reduces Factory Reset Protection problems.

Factory reset and begin setup

Do this before final payment. If previous-owner credentials are requested, stop.

  • speakers and microphones;

Create a receipt
