What is Encrypt Device and Encrypt 

SD Card on android mobile ? 


Encrypting the data on your microSD card adds an extra layer of security. It locks the information on your SD card to your device in it's current state. If it's lost, stolen or removed, the files won't be read even if it is moved onto another device or computer.



It is important to remember to decrypt your microSD card before a Factory Data Reset, or if you are switching to a new phone. The data on your SD card will not be able to be read or decrypted after a reset or in another device. The only option to use the microSD card again is to wipe it completely.

Does Android encrypt micro SD cards?

It can if you want it to. There are actually two different ways.

Android by defaults treats a MicroSD card as usually intended, a portable storage device that can work between different computers. As such, it will format or the card orvuse a pre-existing format of FAT32 (≤ 32GB)or exFAT (≥ 64GB) for interchange according to the SD specs. By default there's no encryption. However, you can switch on encryption, for all files or excluding multimedia files. 

How to Decrypt and Format Encrypted SD Card 

The other option is to set up the MicroSD card as Adopted Storage. This is only done for a card you intend to behave as a permanent part of your phone, as it essentially becomes an extension of your internal flash storage. Android will use the format (probably ext4) and encryption (probably 128-bit AES) that's used on internal flash memory. This option was introduced on Android 6 in 2016. And it can be disabled by your phone's manufacturer, but it is a standard part of Android.

Here are common simple steps for you to follow:

Step1. Open the Setting option of your android phone.

Step2. Select the Security option under the Settings interface.

Step3. Click Encrypt external SD card there.

Step4. Disable Encryption thereby following its guide.

Step5. Reboot your android phone at last.
