How to do a Factory Reset on an Android Phone

Posted by on February 15, 2014

There may be situations where you need to do a factory reset on your Android phone. Factory reset is a feature that deletes all user data, third-party applications, and settings from the device internal storage and return it to the condition when it was shipped from the manufacturer. The feature is supported by almost all mobile devices that running the Android operating system.

If your device is frequently freezing, not responsive, or responding incorrectly, restoring your phone to its factory setting will resolve the problems. It can also be useful if you are planning to sell your phone, so that you don’t handover your personal information to the buyer.

Please note that performing a factory reset will erase your phone data, such as contacts, calendar, apps and messages, so make sure to back up all your important files before you proceed. Now, let’s see how to do a factory reset on an Android phone.

  1. Open the ‘Settings’ menu on your device.
  2. Depending on which version of your Android device is running or manufacturer (Samsung, HTC, LG, etc.), the Factory Reset option may reside in one of many sections within the Settings. In Samsung Galaxy S3, the option is located under ‘Personal’ section.

  4. Select ‘Backup & Reset’ and you will see ‘Factory data reset’.
  5. Tap on the ‘Factory data reset’. This will give you a warning that you’re about to completely delete all your data and restore the factory settings.
  6. Tap ‘Reset device’ and then tap ‘Delete All” to confirm your choice.
  7. It can take up to five minutes for your phone to reset.

Once done, your phone will be almost exactly like it was when you first took it out of the box.

If you can’t turn your phone on or unable to access factory data reset options through the settings then you can still perform a factory reset by booting your Android device into recovery mode. (Read How to Boot Any Android Device into Recovery Mode).

  1. Hi there, l am using Samsung Galaxy S4 GT i9500. My phone is not responding frequently. I am planning to do a ‘factory reset’. I recently updated the OS to 4.3 jellybean from the factory version 4.2. Now l am waiting for KitKat. At this time, if l do a factory reset, will the phone turn to factory version? That is 4.2 jellybean? In this case, can l re-update 4.3 jellybean? If not, can l directly update it to KitKat..? I will go for factory reset after coming into a clear picture on this. Please help me out.

    • Hi, performing a factory reset does not remove OS upgrades, it simply erases all user data such as contacts, calender, messages, logs, and third party-apps.
