How to Encrypt Android Device – Guide
For most smartphone users, encryption is an important thing and if you’re wondering how to encrypt your android phone, there are several options depending on the manufacturer, model and version of Android. Device encryption is not a complete solution to protect all your data and information from prying eyes, even more so when you are sending data over the Internet. Device encryption, however, converts all the data stored on your smartphone into a format that can only be read with the correct access data. This goes well beyond the basic lock screen password provided, as with some knowledge and the use of bootloaders, restores or the Android Debug Bridge, the data behind the screen can still be accessed.
Once your device is encrypted, all your data, including music, photos, apps and accounts, cannot be read without disentangling the information with a unique key. A user password is converted into a key that is stored in a “Trusted Execution Environment” to protect it from software attacks. This key is needed to encrypt and decrypt files, similar to an alphabetic cipher that encrypts letters. On Android, this is very easy from the user’s point of view. All you have to do is enter your password every time you start or unlock your device and all your files will be accessible. This means that even if your device falls into the wrong hands, no one can access the data without knowing the password.
How to encrypt my android device
Device encryption works the same on all Android devices, but the methods for enabling it have changed slightly over the years. Most devices come with encryption enabled by default these days, especially those running newer versions of Android. if your phone is not enabled, you can do this manually with just a few taps.
Android 5.0 or higher
For Android devices and tablets with Android 5.0 Lollipop or later, you can directly navigate to the “Security” menu in the settings. Getting here may be a little different depending on your OEM, but with Android in stock this can be found under Settings > Personal > Security.
Here you should see an option to “Encrypt phone”Or“ Encrypt tablet ”. You will be asked to connect your phone charged with charging while the process takes place, just to ensure that your phone does not turn off and causes errors. If you haven’t already done so, you will be asked to set a lock screen PIN or password, which you must enter when turning on the phone enable it or unlock it to access your newly encrypted files. Make sure you remember this password!
Android 4.4 or lower
If you are running a device with Android 4.4 KitKat or lower, you will have to set up a PIN or password before starting up the encryption process. Fortunately, this is quite simple. Go to Settings > Security > Screen lock and choose a pattern, numbered PIN or mixed password for your lock screen. This will be the same password used after encryption, so make a note of it.
Once that’s done, you can go back to the Security menu and click on “Encrypt phone”Or“ Encrypt tablet ”. you will need to have your phone logged in and read the warning messages, and you will almost certainly have to confirm your PIN or password one last time before starting the encryption process.
Encrypting your phone it may take an hour or more, depending on the power of your device and the amount of data you have saved on the device. Once the process is finally complete, you can enter your PIN and start using your newly encrypted device.
Back in the Security menu, you’ll probably also find an option to encrypt files on your microSD card. This is a recommended step if you want to keep all your data safe, but it’s not really necessary if you’re using your microSD card to save music or movies that aren’t particularly personal.
There are some caveats here too. First, you will no longer be able to use your microSD card with other devices without completely removing the encryption, like others. phones or computers won’t know the key. Although an encrypted microSD card is still completely transparent for moving files to and from USB, as long as you access the encrypted files from the phone used to encrypt it. Also, if you reset your device before selecting decrypt, the encryption key will be lost and you will not be able to gain access to the secure files on your microSD card. So think about it carefully.
