Tips on what to do before selling your used cell phone

It is very common that, when buying a new smartphone, users sell or pass on their old devices, which can help to reduce the value of the new gadget a little. However, given the amount of relevant information that is saved on the devices, before passing on your device there are some important procedures to consider.

Android associates a lot of your data with your account, but still there is some data you need to manually save to gain access to the new device. To help you migrate to a new device with more peace of mind, Tecmundo lists below some important steps to be taken before you transfer your Android device.

Backup your files

The first step in deciding that you are going to change your device without a doubt is to back up your files, contacts and messages. For photos, you can use the Google Photos service and automatically upload them to your Google account, which will make the procedure much easier.

For contacts, the Google Contacts app can also speed up the procedure, remembering that it is important, after performing the backup, to verify that the synchronization occurred correctly. For messages, as well as for other applications, for example WhatsApp, there is a native tool that performs the procedure, being able to save the data in cloud services such as Google Drive.

Gather your passwords

You probably have several services with passwords saved on your device, so it’s important to check which ones you use the most by checking the login mode. Some services allow login through your Google account, as long as it is associated with your account, which can facilitate your device migration.

For other services and applications, it is important to obtain the access passwords and try to store them somewhere or write them down so that you can access the services on the next device.

Unlink your device

Some banking and service apps make the device association to the login to have one more security restriction, in order to not allow access to your account through unknown devices. Thus, before handing over your device, it is essential that you check with the associated service what is the procedure to be performed to complete the change of device.

Financial institutions may require you to use your old device to change your device or even ask you to go to a branch or an electronic terminal in order to receive new access. However, by contacting your bank you should receive instructions on how to proceed.

Device reset

After performing the backup, saving your data and unlinking your accounts, you can reset the device and leave it, to the new owner, as it came from the factory. To perform the procedure, you can either use the Android settings menu or check in your device manual how to proceed to the hard reset.

The procedure through the Android settings follows the following step by step.

  • Access your device settings.

  • Now, just select “Reset to original configuration (factory setting)” and you’re done. The device should restart as if it was being turned on for the first time (the procedures presented were performed on an Asus Zenfone Max device).

If you use a micro SD card, you can use Android settings to format it before passing your device. The hard reset procedure accesses a kind of Android device BIOS, but its access requires some knowledge, having access that can change from one device to another.

Also, don’t forget to remove your SIM card from your old device, and if you want to keep your micro SD card, remove it to use it on your new Android device.
