In basic terms, encryption converts all the data into a secret or random code, in cipher text, which can’t be deciphered by unauthorized parties. On an Android gadget, encryption ensures that only people with the password or PIN can access the data.


You may be thinking, how is that different than your regular PIN or password protection. Well, the data saved on an Android gadget can be accessed through various approaches even if you have set up a lock. If you have an encrypted gadget, the data can’t be accessed or decrypted without entering the PIN or password. For example, if you lose your gadget, the thief might be able to access the data but if you have an encrypted gadget, decrypting the data would require some serious abilities, considering all the data is in random form aka cipher text.

Now, as you may have guessed, this process does take some resources from your device. So, don’t be surprised if encrypting your devicetakes a little toll on the device’s performance. Chances are, you won’t notice the performance difference on a modern day high-end or mid-end device but if you own a low-end or older Android device with modest specifications, you ought to brace yourself for a slightly slow device after encryption.
  • Many Android devices like the Google Pixel line-up, newer Nexus device etc. areencrypted by default and while Google has made encryption compulsory by default with Android 6.0 Marshmallow or later, manufacturers can select to ignore it citing performance issues on modestly powered gadgets. You can check if your gadget is encrypted or not in Settings->Security->Encrypt Phone.
