An encrypted device is far more secure than an unencrypted one. When encrypted, the only way to get into the phone is with the encryption key.

What encryption does Android use?

Android full-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.

Can Android encryption be cracked?

Android encrypts a gadget’s file system using a randomly generated 128-bit Device Encryption Key aka the DEK. However, it’s not quite that simple: the DEK is actually encrypted using the owner’s PIN or password and an encrypted block of data called the KeyMaster Key Blob.

Does Android encryption affect performance?

Yes, encryption in android slows down the device. Android uses dm-crypt, which is an OS-level encryption common in linux-based OSes. Hence, it does slow your phone when there are disk IO operaitons involved. (Apple introduced hardware encryption from iPhone 3GS, so it’s a different story for iOS.
