But most manufacturers don’t encrypt their devices by default, so if you want to protect your data, you’ll have to do it yourself.
Do We Need Encryption?
Considering we store most of our personal data on our smartphones, chances are you need it. If you were to loose your phone, anyone with basic computer knowledge will be able to recover all your pictures, videos, and files, even if your device is password protected.
If you encrypt, your data will be stored in an unreadable form and will not be accessible to anyone that doesn’t have the PIN or the password. On Android 5.1 or above, encryption doesn’t require a PIN or password, but not having one will defeat the purpose of encryption.
With this in mind, here’s how to enable Encryption on devices running Android 5.0 or above.
How to Enable Encryption in Android 5.0 or Above
1. Go to Settings > Security and tap on Screen lock.
2. Set up a PIN or a Password.
2. Go back to Settings > Security, scroll down until you find the Encryption tab and hit Encrypt phone.
3. Make sure your phone is fully charged, connect it to a charger, hit Encrypt phone and enter the password or PIN you previously created.
4. Wait until the process is finished. Keep in mind that it might take up to an hour, depending on the amount of data you have on your device.
5. Enter your Password or PIN and enjoy using your encrypted device.
