It was recently discovered that Google no longer made it mandatory for Android 5.0 devices to come with full disk encryption. This has now been confirmed by the Mountain View giant as the Android 5.0 Lollipop hardware requirements document now mentions that full disk encryption is only “recommended” and not a “must” as it previously was.
According to the company, performance was affected when full disk encryption was suggested to manufacturers, which has forced Google to no longer make it mandatory. The company categorically mentions that it was only the “partner” devices that faced these issues, so Nexus smartphones and tablets probably don’t have any bearing on the performance with a disk encryption.
Google makes it a point to allow users to encrypt data on their devices by heading over to Settings – Security – Encryption.
Here’s the full statement issued by Google:
In September, we announced that all new Android Lollipop devices would be encrypted by default. Due to performance issues on some Android partner devices we are not yet at encryption by default on every new Lollipop device. That said, our new Nexus devices are encrypted by default and Android users (Jelly Bean and above) have the option to encrypt the data on their devices in Settings —> Security — >Encryption. We remain firmly committed to encryption because it helps keep users safe and secure on the web.
