How to Factory Reset an Android Phone or Tablet

Introduction

A factory reset is a process that erases the data on a tablet or smartphone and restores it to mostly the same condition as when it was first purchased.

Your smartphone or tablet has a lot of personal information on it. Before you sell, give away, gift, or otherwise dispose of your phone or tablet, it's good to remove your personal data to keep it safe, and to make it ready for its next owner. As well, if there's some problems that can be solved thanks to a reset.

Before You Begin:

Have your Android phone available.
Ensure your device's battery is charged to at least 75% power - It is recommended to keep your device plugged in while performing the reset.
This process removes all the personal information on your Android device; make sure you have your device backed up before beginning.

1 Factory Reset - Normal Mode

Remove any memory cards before resetting the device.

Each Android device is slightly different, thanks to changes each manufacturer and provider makes to how the Operating System works. Things may be slightly different on your tablet or smartphone.

It can take an hour or more for the reset to complete. Make sure your device is charged — ideally, it's best to leave it plugged in during the reset process

Open Settings, and select System.
Select Reset options.
Select Erase all data (factory reset).
Select Reset Phone or Reset Tablet at the bottom.
You'll be asked to confirm, select Erase Everything.

Keep in mind that the Factory Reset can take some time.
Your device should reboot and may show a progress screen indicating that it is erasing the data.
After it finishes deleting the data on the device, the operating system will restart again and will arrive at a screen similar to the one when you first unpacked it from the box.

Recovery mode allows you to access your Android device before the Android operating system is fully loaded. This lets you make changes you can't make while the device is running normally, such as side-load updates to gain root access or restore a 'shadow copy' of the entire operating system which resets the device.

By design, Recovery Mode is not easy to get into! This is not a feature or function you will need to access regularly, and is designed for developers.

If you are uncomfortable accessing these tools, please reach out to your cell carrier or phone manufacturer, or tablet manufacturer for assistance, instead.

Factory Reset from Recovery Mode

Every phone, tablet, or device is slightly different, and may require a different key combination. If the default, basic instructions here don't work, search the web for "recovery mode" with the make and model of your device.

Push and hold the power button for a few seconds, a menu will open. Select Power Off.
Your device will turn off. Wait five seconds.
Use the Key Combo to enter Recovery mode to boot your device.
