Without middleware, without Google Apps, does Android support the Exchange ActiveSync policy "encrypt storage card."?

According to Wikipedia, Android doesn't support the ActiveSync command to encrypt a storage card. I'd like a second opinion, with a reference.

PS: I've seen Samsung claim the ability to encrypt storage cards, but unless it's through ActiveSync, it's not what I'm looking for.

Prior to Android 3.0 (Honeycomb), Android did not natively supported encrypting local storage at all. Android 3.0 introduced the ability to encrypt the local device, and to enforce device encryption by Activesync policy.

Other than the Galaxy Nexus, every phone currently on the market is running either a 1.x or 2.x version of Android, none of these support device or removable media encryption in the Android OS, it is possible that some manufacturers may have added encryption, but this isn't a standard part of the OS available to standard ActiveSync implementations.

For Android 4.x phones (currently only the Galaxy Nexus) full device encryption (and the relevant policies) is brought to phones but this still doesn't seem to include removable media.


On my Samsung Galaxy S2, adding corporate exchange/ActiveSync account does indeed force encryption of all device storage.


A number of Motorola devices support that feature. Here is a link to their site. My group has the Bionic and Atrix 2 and they support that feature.
