But do how to recover lost partition feel every little thing will likely be fine right after reset? What privacy won't be leaked? Not also. So long as via some technical suggests, it's still possible to recover sensitive data from it.




Researchers at the University of Cambridge have found 21 Android phones from five companies, with system versions ranging from 2.3 to 4.3.




It was identified that soon after restoring the factory settings, some data fragments can nevertheless be recovered, which includes program contacts, SMS, e-mail, and third-party applications.




What's far more serious is the fact that they even restored the Google tokens of all mobile phones. Just after restarting, the mobile telephone will quickly synchronize your Google account information. The system's most important token is also 80% restored effectively.




Why didn't the system-level reset fully erase the data? The researchers think that you will discover mainly the following factors:




1. deleted partition pushed by mobile phone makers are incomplete and have vulnerabilities.

two. The deletion of stored content by Android is just not correct and full, specifically around the SD card.

3. Lack of full-disk encryption just before Android four.four (so only the old version was tested right here).

4. The lack of driver help for correct deletion of data around the most current devices.
