Factory resetting may not delete everything. How to sell your smartphone safely with iShredder Android?

May 08, 2019
Our smartphones are privy to some of our most important secrets. Personal photos, sensitive emails, financial details, contact information, and perhaps even a secret document are not things you want falling into the wrong hands. When users factory reset an Android device, they expect all personal data to be deleted. Unfortunately, when independent security researchers bought Android smartphones from eBay, they were able to recover pictures, Google searches, emails and text messages. According to the researchers, they were able to restore 40,000 pictures, which included photos of children, women in “various stages of undress,” and male nude selfies.

To truly delete all personal data, users must securely overwrite it with certified erasure algorithms integrated in the latest iShredder Android 6.0. iShredder Android from Protectstar is the #1 secure data deletion app for Android smartphones and tablets. iShredder's data erasing algorithms have been analyzed by government authorities, and independent security organizations, to ensure the app securely removes all personal data on your device. 
By simply running iShredder on any Android device, anyone can securely erase data, and even clear all empty free space, ensuring all personal data: including passwords, videos, photos, and more can never be recovered.

"When a user deletes personal files, such as photos from their device, they may think they're gone for good. The truth is, they can be recovered using any one of a number of utilities. Those files aren't really gone until they have been securely overwritten using advanced deletion algorithms," says Chris Bohn, CEO of Protectstar.

On Google's Play Store, iShredder Android is able to securely erase photos, contacts, WhatsApp, thumbnails, personal files and folders, as well as a secure deletion of mounted devices such as external usb sticks, sd cards, and more. 
Detailed audit erasure reports provide users evidence of deletion.

With the new version 6.0, it is also easy to select individual files and folders that you want to securely erase by using the integrated File Explorer, allows users an easy access and selection of data, such as personal files or photos from the Android gallery, and completely erase them with ease.

iShredder Android 6 is available in four editions, the free Standard edition offers 6 deletion algorithms, the Professional Edition offers 12, the Enterprise Edition 18, and the Military edition offers 23 wiping methods in total.

Depending on the edition, iShredder comes with deletion algorithms such as DoD 5220.22-M E, BSI-VS-2011, US Army AR380-19, DoD 5220.22-M ECE, BSI/VS-ITR TL-03423, CSEC ITSG-06, NATO Standard, Gutmann, HMG InfoSec No.5, DoD 5220.22 SSD, Navy NAVSO P-5239-26, USAF AFSSI-5020, German BSI TL-03423, CSEC ITSG-06, and many more.
