Digital Trends reported on built-in encryption for Andriod L.
The next major version of Android is going to come with one feature that will please the security-conscious: built-in encryption. It means anyone who grabs hold of your mobile device—from petty thief to law enforcement officer—will find it much more difficult to extract data from it. The same level of advanced encryption is also available in iOS 8.
Android users have had the option to encrypt their phones and tablets since 2011, but the setup process for Android L will switch it on by default. iOS has always encrypted data on devices automatically — there’s no option to enable it as there is on current versions of Android — but the protection has been reworked and improved in iOS 8.
Let’s not talk about why it’s always on for iOS while Android makes it turned off by default. Given how Android updates are rolled out, it will be years before this is widely adopted.
