From Reason.com:

Observant tech journalists have noticed something big in their latest privacy notes. Apple has changed its encryption so that the company itself cannot access the data on its users’ phones and iPads without the passcode. Thus, if police or the feds come to Apple with warrants to grab potentially useful private data off a device, they couldn’t comply even if they wanted to.

From ArsTechnica:

The Washington Post is reporting that Google will finally step up security efforts on Android and enable device encryption by default. The Post has quoted company spokeswoman Niki Christoff as saying “As part of our next Android release, encryption will be enabled by default out of the box, so you won’t even have to think about turning it on.”

The move should bring Android up to parity with iOS. Apple recently announced enhanced encryption for iOS 8, which Apple says makes it impossible for the company to decrypt a device, even for law enforcement. While Android’s encryption was optional, it seems to work in a similar way, with Christoff saying “For over three years Android has offered encryption, and keys are not stored off of the device, so they cannot be shared with law enforcement.”
