Android
devices that comes directly from factory are encrypted by default,
but the devices which just got an Android Lollipop update, what about
them? So for them there are some process to follow and encrypt your
device.
All
Lollipop devices will come from the factory with device encryption
enabled by default. Device encryption is enabled only on brand new
piece of Android. So when you update an existing device with revised
version of OS eg: Nexus 5 or any other Android device then there are
two options to encrypt your device.
The
most likely method to enable encryption on a freshly updated device
is to manually enable it through the Security menu. For most devices,
this can be found by launching the Settings
app then tapping Security.

As
you can see in the screenshot above, the Nexus 5 I have (which was
recently updated) is not encrypted. By tapping on Encrypt
phone
you'll be walked through the process for securing your data.
Keep
your device connected to a charger as entire process takes an hour to
complete. A Nexus 5 with no apps or services setup currently shows
it'll take over two hours to complete encryption.
The
second option to encrypt a newly updated Lollipop device is to
factory reset it. Yes, that means completely wiping all of your data
from the device and setting it up as brand new. During the factory
reset process the device will encrypt itself, making your data harder
to access. A factory reset can be done by launching Settings,
tapping on Backup
& Reset,
followed by Factory
Reset.
Even
if you aren't on Android 5.0 Lollipop, I suggest encrypting your
device anyways.
