What is Android Encryption?

The official team of Android developers understand that the world has become much more dangerous, and data is everything in this decade. The developers have added a security option for every Android to the user to add encryption to your internal smartphone memory, and SD card.

The Android OS will add a series of codes to your internal memory that can be accessed with a PIN, or a Password you create during the encryption process.

The Android OS does not let the privacy invaders access the content inside the memory because the hacker will have a hard time understanding the encryption. The Android OS encryption is the first-class encryption, and it would take several geniuses to decrypt it down with a valid password.

In simple words, Android encryption is a security feature for those who don’t want to share their data with anyone except themselves. In addition, no one could get a single piece of data from the device if the phone was lost or get stolen. There are a few smart programs out there such as Androidphonesoft, which can easily recover data from Android devcie.

How Android Encryption Prevents Unauthorized Access?

Let’s assume that your Android smartphone is stolen, and you no longer have access to it. You smartphone internal memory, and SD card content can be accessed by the unknown person anytime they want it. Your data is not secure in someone else hands, and they can misuse it, which can cause you a great deal.

Now, let’s assume that you have enabled Android encryption on your internal memory, and external memory (SD card.)

1: Every time you connect the device to another computer, then it will prompt you to enter the password you created during the process. In simple words, no one can access internal memory without a password.

2: The same prompt will ask you to enter the password for external memory as well. Now, assume that culprit has removed the SD card from the phone, and trying to access it via USB card reader, then what happens? The Android Encryption prevents the unauthorised user to access it, even when the SD Card is removed.

There is a popular saying in English “PROTECTION IS BETTER THAN CURE.”

The Android encryption does the same job for you.


The minimum requirement to enable Encryption, then you need an Android 5.0 Lollipop on your smartphone.

Android 5.0 Lollipop or above: You can enable Full-disk encryption that uses a single password, or key to unlock it. Do not panic when you are unable to utilise the functions like Voice calling, Alarm, Calendar, Internet, and more. You have to use the key each time to give it access to your disk, but once you get the hang of it, then it becomes your everyday cup of tea.

Android 7.0 Nougat or above: Android added an amazing File-based encryption feature that lets you encrypt one file, and set one key for every folder. You don’t have to encrypt the entire disk, and you can use different API keys for every folder.

Battery Charge to 100%: Connect your smartphone to the charger during the process, and charge it to 100%, or it won’t work.
