Furthermore, because Android manufacturers can digitally sign and flash TrustZone images to any device, they can comply with law enforcement requests to break Android full-disk encryption.

Google is stepping up and mandating full disk encryption in Marshmallow (again). This time, we hope the feature sticks.

For example, Google has implemented end-to-end encryption for RCS between Android devices, but end-to-end encryption between Android and iPhone has not been realized.

Since Android 10, all new devices use file-based encryption. For older devices on an older OS, you might have optional encryption, but it isn't enabled by default.

CTIA Device of the Day: Galaxy Tabs feature device-level encryption, a first for any Android device, and Samsung, unlike Apple, had the enterprise in mind when developing its tablets.

However, between an Android device and an iPhone, there currently is no encryption. The industry is at least telling us that they are working on it.

This caused chat messages between iPhone and Android users to be unencrypted. Fortunately, Apple has already agreed to update to the latest RCS protocol, thereby permanently fixing the issue.

The GSM Association promises end-to-end encryption is coming to the Rich Communication Services messaging standard, which will better protect communications between mobile devices.
