If you decided to buy a used phone then you need to make sure that you are not buying pig in a poke. To avoid any problems make sure to perform device check before you hand the money to the seller. To help you keep in mind every detail we created a little checklist about what and when you need to check.
First of all you need to visually examine the device. Look for any scratches or cracks not only on the screen, but also on the side panels, and especially in the corners. Then turn the phone to see its back. If on the outside everything satisfies you, then open the back cover to check the battery and any signs of water damage. The battery must be original, if it is not, ask the seller about the reasons why it is not. Then take the battery out and look for any rust stains that will symbolize water damage. Today you can often see cheap iPhones where the battery does not go out. So in this case you should look for special signs also under the back panel that will have a different color after contact with water.
In terms of battery check it is also very important to check whether this component is original. Original batteries tend to work longer in general and also have better accumulation features. If the battery is not original, ask the seller why it is so. Maybe, he or she changed it because the old one failed and maybe because they want to fool you. Keep this fact in mind.
You also need to make sure that the battery is charging. To check it simply plug the phone into the socket and wait several minutes for the result.
SIM card check is very simple. Just put your SIM card into the phone and turn it one. Try to make several phone calls and send messages to ensure that the phone ‘sees’ your card and it functions properly. After the basic check turn the internet on and try to work with several apps to ensure that everything works correctly.
Moreover, with such simple check you also can find out whether the phone is locked or unlocked.
Buying a locked device is one more problem that you may face. Locked phones work only with the carrier they were initially created to and cannot be switched to anything else. According to the professionals unlocked smartphones are pricier but at the same time more universal, so they vote for unlocked models. If you turn the phone on and it says ‘wrong SIM card’ then you face the issue of a locked phone.

And the final tip from our experts is to check the sound system of the phone. For example, we will take Blackberry 9900. Turn the music on and listen to it, then plug the headphones and make sure that you perfectly head all the sounds in both of them. A little tip here is to listen to the alarm too.
