What is android Encryption:
Android includes a system encryption feature that encrypts all data – including application data, downloaded files, and everything else – on your phone or tablet. You’ll have to enter your PIN or password each time you turn on your phone, For the average person without sensitive data on their phone, encryption isn’t likely to matter as much. If your phone is stolen, most thieves would also be deterred from accessing your data by a standard unlock code. The thief would likely be more interested in wiping and selling the phone rather than accessing your personal data. Source Data from: http://www.howtogeek.com
How Android encryption works
Android disk encryption is based on dm-crypt, which is a kernel feature that works at the block device layer. Because of this, encryption works with Embedded MultiMediaCard (eMMC) and similar flash devices that present themselves to the kernel as block devices. Encryption is not possible with YAFFS, which talks directly to a raw NAND flash chip. Data Source form https://source.android.com
