[Solved] How to Permanently Erase the Data on Android Devices

Why do you need to erase the data on Android devices?

Smartphone has become the digital extension to most phone owners, and a carry-on item that people are not willing to give up. Because it is indeed a universal gadget that is not only a communication tool but a memory unit and a mobile encyclopedia. Insomuch, it holds a whole bunch of personal user information like photos, contacts, email or more. Naturally, for protection of personal privacy, it’s better to erase the data on Android, suppose you’d like to resale the phone or give it away to others.

Is factory reset enough to fully erase the data on Android?

In general, most persons clear the phone data by formatting it. However, you really believe that these operations are effective to completely erase the data? It’s undeniable that factory reset could clear part of them. But this operation couldn’t remove all. The rest of the data is stored in the place invisible to you. Of course, if you plan to give the phone away to close friend or family members, factory reset is enough for you. However, if you expect to resale it online, it is not a wise operation.

As for the reason…Avast, a security software vendor, once made a study to prove that factory reset option isn't effective in eradicating the personal data. His company purchased 20 used Android phones on eBay, and was able to recover 40,000 photos, 750 emails, and 250 contacts.The contacts are along with the identities of previous device owners. What’s worse, the employees were using readily available data recovery software to get the job done. Unconsciously, the former owners of the 20 smartphones have divulged the personal privacy.

From what I have said above, you’d better finish the data-erase work by Android data eraser. You could refer to the operations below to complete it.
