Some devices will also allow SD card contents to be encrypted, but by default Android just encrypts on-board storage. If your device is already encrypted, it will show up here. Start by heading into the Settings menu and tapping on “Security,” again keeping in mind that the wording may be slightly different. With all the caveats out of the way, you’re ready to encrypt your device. Once the process is started, it’s best to just leave the device alone and let it do its thing. If you interfere with the process or end it before it’s finished, you will likely lose all your data. Again, if you’re rooted, be sure to unroot your phone before continuing!īasically, make sure you’ve got plenty of time and battery before you start the process.Your device must be plugged in throughout the entire process.Android won’t even start the process otherwise. Your device’s battery must be at least 80% charged.Encrypting the device can take an hour or longer.

How to Enable Encryption in Androidīefore you get started, there are a few things worth noting: For most people, we think the added protection is well worth it. These aren’t meant to deter you from encrypting your phone-just to give you an idea of what caveats it comes with. You can encrypt your rooted phone, but you’ll have to unroot it first, go through the encryption process, then re-root afteward. If you’re rooted, you’ll need to temporarily unroot: If you try to encrypt a rooted phone, you’ll run into problems.So make sure you’re sure before you start the process. Encryption is one-way: If you enable encryption yourself, the only way to undo the process is by factory resetting the device and starting over from scratch.Therefore, you may see a bit of a performance drop once it’s enabled, though it’s generally not noticeable for most users (especially if you have a powerful phone). Slower Performance: Once a device is encrypted, the data has to be decrypted on-the-fly every time you access it.But if you’re using a device that doesn’t have encryption enabled out of the box, there are some things to consider before enabling it: If this is the case for your phone, there is no way to disable encryption. Most newer Android phones ship with encryption already turned on by default. Things to Consider Before Enabling Encryption But, it never hurts to keep that stuff protected. And, most thieves are more interested in wiping and selling the phone than accessing your personal data. Granted, most thieves would also be deterred from accessing your data by a standard unlock code-encrypted or not. If you’re an average user, you may think you don’t have sensitive data on your phone, but you probably do. If your phone is stolen, that thief now has access to your email inbox, your home address, and any number of other pieces of personal information. An attacker won’t be able to access the data without the encryption key, although there are more advanced cracking methods that make it a possibility. For example, corporations with sensitive business data on company phones will want to use encryption (with a secured lock screen) to help protect that data from corporate espionage. (On Android 5.1 and above, encryption doesn’t require a PIN or password, but it’s highly recommended since not having one would reduce the effectiveness of the encryption.)Įncryption protects the sensitive data on your phone. If someone doesn’t know the encryption PIN or password, they can’t access your data. It’s the same technology used by a variety of Linux distributions.) When you enter your PIN, password, or pattern on the lock screen, your phone decrypts the data, making it understandable. (To actually perform the low-level encryption functions, Android uses dm-crypt, which is the standard disk encryption system in the Linux kernel. Encryption stores your phone’s data in an unreadable, seemingly scrambled form.
