Check the details.
Compare the model and serial shown in settings with the device and receipt. Ask who owns it and for proof that the seller can sell it. A copied serial can look valid.
THE QIA TECH FIELD GUIDE
Good questions.
Better tech decisions.
Useful checks for your next purchase and the tech you already own.
Open My Tech ↗BUYING A USED DEVICE
A number is a start.
Check the whole device.
Check the locks.
Ask the owner to remove their account locks properly. Do not buy a device you cannot activate or sign into. Do not ask QIA to bypass someone else’s account.
Check it working.
Try the screen, keys, ports, WiFi, audio, camera and charging. Ask about battery condition, repairs and missing parts. Check the exact specs, not just the product name.
Check what happens next.
Get the price, condition, warranty provider and returns terms in writing. Manufacturer coverage does not prove ownership, guarantee condition or replace a seller’s terms.
SOFTWARE SUPPORT IS ITS OWN DATE
Check the exact version.
A warranty date, subscription date and end of software support mean different things. Check with the provider before deciding what to do.

Check edition, region and any extended-support arrangement. These links are sources to consult, not an automatic check of your installed software.

WHERE THE CHECKS COME FROM
Know the source.
