It’s always a good idea to think twice before downloading certain apps or accepting the permissions that they request. To add an extra layer of security, you can encrypt the data that you store on your mobile phone. That means it’s only accessible to you after you’ve entered your password.
But you might be thinking, “Why do I need this? I already have a pin code!” Well, they don’t actually serve the same purpose. Encryption ensures that all your data is unavailable, even if someone connects the phone to a computer and tries to hack it.
Please take into account that encrypting your phone will make it a bit slower, and that encryption is a one-way street! The only way to "un-encrypt" your phone is to go back to the "Factory Settings", and that means losing all your data.
How-To Geek does a good job of explaining the encryption process, including the advantages and pitfalls. If you have additional information or links, feel free to share in the comments!
If you still want to encrypt your phone, just follow these steps:
1) Go to System Settings
2) Tap on Security
3) Tap on Encrypt phone
Happy encrypting! It will take a while before the process is complete. Grab a magazine and relax for a minute.
