How to Reset Android Phone to Factory Settings (Fully Erase Everything)
Before selling any computer, smartphone or tablet, it is essential to protect your privacy by formatting the device. Formatting – as you surely know already – is a process by which you delete all files on a drive keeping it serviceable.
Be careful though: simple formatting is not enough. To make sure that your old data has been truly deleted and cannot be subsequently recovered with some specialist software (like the ones I mentioned in the tutorial on how to recover photos on Android), you need to overwrite all the empty space on the drive using a process called “wiping”.
I know that it may seem like a tricky thing to do – a prerogative of experienced users – but it really is not so. In order to prove it, I will now explain how to format Android and how to “wipe” a smartphone or a tablet using some free apps. I bet you will be surprised by how simple it is!
Preliminary operations
Backup
Before formatting your device, save a backup copy of all its files and apps. There are a lot of apps suitable for the purpose, and I will point some out to you right away:
- Titanium Backup (Need Root)- the best app for backups on Android devices. It saves apps and data on external or internal storage. I have explained how to use it in quite some detail in my guide about how to backup Android.
- EasyBackup – another backup app, less powerful than Titanium but works without root access. You can find info and instructions on how to use it in the post about Android backup I have just linked.
- SMS Backup & Restore – Excellent free app that lets you back up all text messages saved on your phone.
Speaking about text messages, I must point out my post on how to re-install WhatsApp where I have shown you the proper steps to save WhatsApp chats and restore them if necessary
