Old iPhone are used products with many different conditions and it is difficult for users to check and choose to buy an iPhone like that.

In the following article, I would like to share a few ways to help you check your old iPhone before buying.

Check out appearance

The exterior of the iPhone is always the top criterion when choosing to buy any old phone . Double check your phone for too much scratches or scratches due to impact.

Check imei

This is an action not to be missed to ensure your iPhone has not been replaced. On your phone, press * # 06 # to check iMei on your phone. Then you can compare the iMei printed on the sim tray or the back of the device. If there is a match, you can rest assured that the phone has not been replaced.

Check iPhone warranty information

Check if the device is locked iCloud or not

Always make sure that iCloud is completely logged out on the device. ICloud-attached devices can become a brick if you accidentally restore your phone.

To check iCloud you refer to the article " Check iCloud on Apple Devices ". Or you can ask the seller " Factory reset iPhone " for you.

Test the response of the hard key

Keys such as home, volume or power buttons are used a lot so you should check the sensitivity of the keys. Do not choose to buy products with hard keys, sideways or low sensitivity.

For the Home key, you try to set up fingerprints and check if the fingerprint is really working well.

Check the screen touch area

You check if the old iPhone screen has good touch by holding down an icon on the screen (You can turn on the virtual home button to do it), moving the icon to any point on the screen. If in any position but the icon stops, there may be a problem with the sensor.

Check if the device has a screen replacement

A pretty useful tip when testing iPhone 5s and iPhone 6 is to remove the sim tray and look into the sim slot, then turn on the screen. If the iPhone has been replaced or dropped, the sim slot will light up.
