Steps to Delete Data from Android Permanently Before Selling

Step 1. Make a Backup Before Deleting All Data from Android

Before you go ahead and begin to erase your data, you might prepare to back up some of your important files. You can choose to transfer Android data to your computer, back up with cloud services like Google Drive, Dropbox, OneDrive, etc., or directly move data to your new Android phone or iPhone. So, you can restore the data backup whenever you need it. Here are some of the quick ways to transfer data to a safe place before a factory reset.

Method 1. Back-Up Android Files to the Cloud

One of the easiest ways to back up some of your Android files is to use a cloud backup. And for Android users, Google offers a free phone backup solution and you can use it to backup & restore Android phones.

What will be backed up to Google account:

If you want to back up other file types, use Google Photos or Google Drive. Using this method does not require an app since the backup option is built right into your phone. To back up with Google:

  1. Launch the Settings app on your Android phone.
  2. Scroll down and tap the System option.
  3. Tap Backup on the screen that follows.
  4. You should see a toggle that says Back up to Google Drive. Turn this option on and your phone will be backed up.

Method 2. Back-Up Android Files Locally

If you do not have a fast and stable Internet connection, or you do not want to use online backups for some reason, you can back up your phone locally to your computer as well. This basically includes plugging your phone into your computer and copying the files that you wish to preserve.

Keep in mind that you cannot back up your settings and other items while using this method. To transfer files from Android to the computer with Android File Transfer:

  1. Head into Settings > System > Developer options on your phone and turn on the USB debugging option.
  2. Plugin your phone to your computer using a USB cable, pull down the notification bar and use File Transfer as the connection mode.
  3. If you are on a Windows PC, your phone should appear under This PC. If you use a Mac, install and use Android File Transfer. (Tips: How to fix Android File Transfer not working)
  4. Copy all of the files you want to preserve from your phone over to your computer.

Step 2. Remove Google Account from Your Android Phone

Before you can reset your phone, you need to remove the Factory Reset Protection from your device. Factory Reset Protection is a lock that can protect your phone from being lost or stolen, which is introduced from Android 5.0 Lollipop. The FRP is enabled automatically when you registered a Google account on your phone. And the FRP lock will be activated after your phone was factory reset in an untrusted environment. At the time, the one needs to enter your Google account to verify.

To disable factory reset protection, you need to remove your Google account from your phone:

  1. Open the Settings app on your phone.
  2. Tap Accounts to view your added accounts.
  3. Choose your Google account in the list.
  4. Tap Remove Account to remove your account from your device.

Step 3. Encrypt Your Phone’s Data

You can apply encryption to your device data, and this way even if someone manages to access your data, all they will see is some gibberish text and not your actual data.

  • If your Android phone came with Android 6.0 or later out of the box, your phone automatically encrypts your data. You need to check which version of Android you are running first: Launch the Settings app > Scroll all the way down and tap About phone > You will see your Android version.
  • If you are on an older Android version, head into Settings > Security > Encrypt phone to encrypt your data.

Frequently Asked Questions about Wipe Android Before Selling

You probably have a few questions about erasing data from your phone, especially if you are doing this for the first time. The following answers to your questions.

1. Does factory reset remove all data permanently?

Factory reset removes all your data from your phone. This data, in most cases, is permanently deleted. However, some recovery tools might be able to find and restore this data. You need to shred your files for good to ensure they can never be recovered.

2. If I erase my old phone, will it affect my new one?

No, if you erase your old phone, that will not affect your new phone. However, if you do not back up your old phone, you will not be able to restore your data on the new phone. This is because the new phone checks your Google account for any backups, and if it does not find any, it will not prompt you to restore your data.

3. How to wipe a Samsung phone?

If your phone or tablet is Samsung, you can wipe a Samsung with some extra tips as below:

  • Remove your Samsung account: Go to Settings > Tap Accounts and backup > Click Manage accounts and find your Samsung account > Choose Remove account from the bottom of the screen > Enter your password to sign out.
  • Erase all data on Samsung remotely with Samsung Find My Mobile: Go to on your phone or computer > Sign in to your Samsung account > Choose Erase data > Enter your Samsung account password to confirm.
