Before we go through how to enable it, we must know about Android Encryption. Why is it so called? What does it? What is its impact on your cell phone? Let’s take a view about it.
What is Device Encryption?
Encryption stores your phone’s data in a form that can be read only when your Android phone or tablet is unlocked. Encryption adds protection if your device is stolen. To get the most protection, you are always required your PIN, password or pattern when your device starts. Encryption stores your mobile phone’s data in an unreadable form. Indeed, the practice of encryption is much more technical than requiring a PIN code or password to unlock a device. When you enter your PIN or password on the lock screen, your phone decrypts the data and makes it understandable.
Big Reason to Encrypt your Data
A full Factory Reset leaves data behind on an Android Phone. When you delete something from your phone or computer, it marks the place where it is stored as OK to overwrite. Some people think that they have cleaned up space, but it’s not the reality. Your data still exists on your phone even after Factory Reset. The solution is Encryption of your Data. Whenever you do the factory reset your cell phone, you should encrypt your data. Its benefit is that no one can access yours from your cell phone. Encryption forces a chunk a change to every chunk of memory available. So Encryption is a big need for you.
What Data gets Encrypted?
All your data is encrypted on you encrypted device. The data includes your emails, texts, contacts, Google Account data, app data, photos, media, and downloads and much more. If you want to set removable media to be encrypted and decrypted, you should format them as internal storage for that device.
How Does Android Encryption Work?
Encryption needs you to have a pin or password on your device. If you don’t have it, you will defeat the purpose. If your phone is accessible by anyone, they can easily get access to the file manager and copy the data. No matter you’ve turned on encryption. If you have a passcode lock, no one can get access to the files stored on your device. It doesn’t matter whether you are connected to a PC or not.
Secondly, encryption works only for the files stored on the internal storage on some devices. In this case, your SD card storage will be an open source for others to access.
After enabling encryption and PIN lock, you’ll need to enter the PIN immediately after booting up the phone otherwise it won’t work. Also, disabling Android Encryption is not that easy. For this, you are required to factory reset your cell phone.
Encryption of Some Devices
Some devices are not encrypted by default. For example, Nexus 4, Nexus 5, Nexus 7, and Nexus 10 devices are not encrypted by default.
Steps of Encryption are written below:
Step 1: Before Encryption
On these devices, the Encryption process can take an hour or more. Also, the device may restart several times. If the encryption process gets interrupted due to some cause, you may lose some or all of your data. So, be careful.
• Make Schedule an hour on more.
• Plug your device into a charger in the case of low charging.
• Check which Android version you have on your cell phone.
Step 2: Encrypt your Device
There are almost 24 Android versions so far. There are two ways of Android Encryption due to the two types of Android Devices.
Encryption of devices running Android 4.4 or below.
Encryption of devices running Android 5.0 or above.
• For Android 4.4 or below.
1. Set a lock screen PIN, Password or Pattern if you don’t have.
2. Go to your Device’s Setting.
3. Tap Security.
4. Tap Encrypt phone or Encrypt tablet.
5. Carefully read the information.
The “Encrypt phone” button will become a little bit dimmed if your battery is not charged properly or your device is not plugged in.
After encryption, you can turn off encryption only by factory data reset.
Let’s say; you are using an accessibility service for example TalkBack, or a Bluetooth-paired accessibility device. Then you will have to enter your PIN, pattern, or password at start-up
If your mind changes about encrypting, tap Back.
6. Tap Encrypt phone or tablet.
7. Enter your lock screen password and Tap continue.
8. Tap Encrypt phone or tablet again.
9. After the completion of Encryption, you will need to enter your password.
• For Android 5.0 or above.
1. Open your device’s Settings.
2. Tap Security.
3. Tap Screen lock button.
4. Tap Pattern, PIN, or Password button to choose your screen lock.
5. You will find “further protect this device.” There you are to enter your PIN, pattern, or password when your device starts. When you choose this setting, it will encrypt your device.
1. Select Require to start device button.
2. Then Tap Continue.
6. Set your PIN, pattern, or password and Tap Continue.
7. Confirm your PIN, pattern or password, and Tap Ok.
Big Flaws of Encryption
There are two big flaws of Encryption which will affect your phone or tablet. First one is Protection and second is Performance.
Your data may be lost if something goes wrong. The main disadvantage of encryption is protection and security. So, be careful while encrypting your device.
Encryption also causes the performance of your device. Encryption may slow down your speed of processing. Encrypted devices may slower down your phone as compared to a unencrypted phone. Almost 40% of your phone’s speed slows down.
