Note the following before factory resetting your Android device

Once a while, it becomes necessary to do a factory reset on your device. A factory reset (or a master reset) is simply returning a device to how it used to be fresh out of the box.  It removes all user data such  as third party apps, call logs, messages, contacts, and any other file  stored on the device memory and wipes the cache partition.

A factory reset, however, does not affect files stored on the memory cards.. For rooted devices, a factory reset will not remove files which have been written to the system partition, this is because factory reset does not mess with the system partition where the device’s stock files are stored.

Remember to backup your apps and files before you factory reset your device. It also does not downgrade your operating system because such updates are written to the system partition.

Why factory reset your Android device?

  • For a clean start (usually applies to advanced users)
  • When Safe Mode doesn’t solve an issue
  • To remove a file that is difficult to remove (like malicious apps)
  • To remove personal information from the device before selling or giving away
  • Messed-up default settings
  • Forgotten password or screen lock pattern

Before you start

  • Make sure you have over 50% battery power
  • Make sure you have your apps and files backed up
  • For devices with device protection, you’ll need to enter a Google username and password associated with the device after factory reset. If you don’t have this information, you won’t be able to use the device at all after factory reset
  • For most device running Android 5.1+, if you recently reset your Google Account password, wait 24 hours before performing the factory reset.

How to factory reset

There are three main ways to factory reset a device

  • Remote wipe

Android devices can be factory reset using Android Device Manager. This tool can be used on the web and on the Android app. It is particularly useful if your device is missing and you cannot track it and want to wipe all your data. Android Device Manager also gives you the opportunity to ring your device or lock it. This will work as long as you have your Google account signed in on the device.

When initiated, the device will receive a wipe command from Google’s servers when it comes online and invokes the standard Android Device Administration API reset function.

Go to Settings > Backup & reset > Factory data reset > Tap Reset Phone
