      Do this before selling an old phone, otherwise you may fall into danger

      The average lifespan of a smartphone is 3-4 years, i.e. 3-4 years. A smartphone can be used without any problem. But say product culture or say technology addiction, most people have not used a smartphone so far. Smartphone technology changes every year. Every year new features come to the smartphone, which makes it no longer willing to use the old phone. The number of users who have been upgrading to smartphones has been increasing steadily since 2016. Sometimes it happens that five-six months after buying a smartphone, we choose another smartphone, so we sell the old phone in an exchange offer. But before exchanging or selling an old smartphone, we need to be careful about certain things, otherwise our information may fall into the hands of someone else.

      If you are an Android or iOS user, all data should be erased before replacing your smartphone. If you do not sell the smartphone by factory reset or data wipe, your personal information will be in the hands of those who will use the exchanged smartphone. Today we will talk about what you should keep in mind before exchanging or selling your old smartphone.

      Data backup

      Before replacing your old smartphone, you need to back up your smartphone data so that your contacts or other personal data can be used on the new smartphone without the risk of data loss.

      Data backup for Android users

      If you’re an Android smartphone user, you’ll need to use Gmail or a Google Account to back up your smartphone’s data. First of all, you have to go to the settings of your smartphone and search for the ‘System’ option. In System Options you will find Data Backup Options. There you can backup data using your Gmail account.

      If you want to backup contacts separately, go to phone settings and tap on account option. Then you will get Sync option in the account. You can sync contacts by tapping there. After syncing the account, all your contacts will be linked to your Gmail account.

      Photos and other information you can back up separately. For this you need to go to the file manager or file option of the smartphone and tag it in Google Drive. Here you can backup files. This way you can back up all photos, videos and other important files.

      Date backup for iOS users

      If you are an iPhone user, the data on your smartphone will be backed up to iCloud. To back up data you need to go to settings option and tap in place of your name. Then you can go to iCloud Backup and turn on Daily Backup. You need to tap on Back Up Now to get a quick backup. This way all the data on your smartphone will be backed up. You can back up your contacts to Gmail or Google Drive if you wish.

      Factory reset

      It is important to do a factory reset on your smartphone after backing up the data. Your phone should be exchanged only after a factory reset. To perform a factory reset on a smartphone, go to the phone’s settings option and tap on system. After tapping on the system, you will get the option to do a factory reset. If you tap this option Erase all data here, the factory will be reset. This way the account linked to your smartphone will be removed and the phone will be as empty as before. Then if you want to exchange or sell the smartphone there will be no risk of data theft from the phone.
