The short answer
For a used iPhone, confirm the seller has removed Activation Lock and that setup can proceed. Then compare condition, carrier compatibility and core functions. No short checklist guarantees a device has no hidden fault.
Read the diagram as text
- Ownership. Can the legitimate seller prepare it for your use?
- Compatibility. Confirm the exact model and intended carrier.
- Functions. Inspect display, touch, cameras, audio and charging.
- Agreement. Keep the described condition and return terms.
Resolve account locks before the handover
Apple's pre-owned iPhone checklist says not to buy an iPhone with Activation Lock enabled. The seller should handle their own account credentials. Do not accept a promise that an unknown unlock service will resolve the problem later.
For Android or another platform, use that manufacturer's current transfer and account-removal instructions. This guide does not provide a lock bypass. If the seller cannot demonstrate legitimate transfer, stop the transaction rather than trying to work around ownership controls.
Confirm the device you are actually receiving
Compare the model in the device settings with the listing and any purchase record the seller provides. Ask the intended carrier to confirm compatibility and any relevant restrictions. A case, colour or box alone is not enough to identify the phone's configuration.
Keep serial numbers and account information out of public posts. A successful compatibility check is not proof that a phone has never been lost, damaged or repaired. Treat each check as one piece of information rather than an overall certificate.
Inspect the body and screen in good light
Look for cracked glass, bent edges, gaps around the enclosure and damage around ports. Check the screen with an ordinary image and normal brightness, then try gentle touch input across the areas you use. Do not press hard to make an intermittent screen respond.
If the body looks swollen or the screen is separating, stop handling it as an ordinary purchase inspection. Ask for safe handling advice. Do not accept a swollen device on the assumption that a simple battery swap is the only work it will need.
Try the functions that matter to you
Apple's checklist covers cameras, audio, buttons, battery information and available parts history. Use a short non-private photo, recording and playback comparison. Check charging with a suitable accessory and inspect any messages shown by the device.
Some information depends on the model and software. An absent warning is not proof of original parts or a complete repair history. For a camera or audio issue, use our focused guides to describe the result rather than rushing through a vague "everything works" test.
Keep the agreement as clear as the inspection
Record the seller's stated condition, included accessories and return terms before committing. If you cannot complete a meaningful inspection, treat that uncertainty as part of the decision. Do not let urgency replace the ownership checks.
For example, a clear screen and working camera do not compensate for an unresolved owner lock. Equally, successful setup does not reveal every intermittent hardware fault. A professional assessment may provide more information, but no brief check can promise a fault-free future.
Keep these notes for your next step
Useful notes: verified model, owner-lock status, carrier confirmation, visible damage, function results and the seller's written terms.
