How to Permanently Erase Everything on Android Phone or Tablet


The growing concern towards privacy on Android device has been increasing sharply in recent years as we almost put the most import data and asset on those devices, such as contacts, photos, videos, login details, purchase history, etc… Obviously, none of us want those data being accessed by unauthorized parties. That's the reason why we need to delete everything permanently on the old Android device we are going to sell it out.



Part 1. Why 'Simple Deletion' and 'Factory Reset' Won't Wipe Everything


The built-in factory reset is the most widely recommended and adopted data erasing method for most of Android users. However, there is a hidden bug laid on it if you didn't take it seriously. I found out occasionally that the data was still available by using certain data recovery software if you go with the default factory reset. It's very dangerous to get your privacy data exposed to someone who you are not familiar with. And you have no idea what he or she was going to do with the found data.


There are many Android data recovery softwares in the market can easily scan all "already deleted data" and the data from a "Factory reset" phone. See why factory reset won't delete everything on Andriod.


Here we choose any two of Android data recovery softwares to test how they scan deleted data from Samsung phone.

The deleted data is still available unless it was over written by others. It's pretty hard to get it done manually, but it can be easy with the help of automation programs.
