Data security on Android

The biggest data generator is in our pockets – so securing it to protect privacy is the very first step to do before starting to use a device.

Steps to secure Android

  • Remove all non-needed apps
    • Acquire root permissions on your phone (phone specific, use XDA forum)
    • Use Titanium Backup
      • Backup all your data
      • Freeze or uninstall all non necessary programs
        • Remove all which is vendor specific (Samsung, Sony, MIUI fork, …)
        • Remove all Google packages
    • Disable all unused or privacy wise dangerous services with Disable Services
      • If some vital functions are not working you can re-enable it
      • Regularly, apps with disabled services still work (e.g. disabling LocationAccess for Facebook app)
