How to protect data in memory on an android smartphone?

Question

Android

Hello.
I use the phone meizu mx2
Always worried about this question. The device supports the ability to lock the phone with a password, but I can easily see the contents of the phone's memory via usb (photo, etc.).
Is there a way to hide this data on flash memory?

Hello. Everything is very simple by encrypting your data.
1. First of all, set a password or PIN to lock your screen. This password or PIN will form part of the key to decrypt the data, so it is important to set it up before starting encryption.
2. After setting the PIN or password, go to the “Security” subsection of the main menu and select “Encrypt Phone” or “Encrypt Tablet” (Encrypt Phone or Encrypt Tablet). On different devices, the menu for data encryption may be located in different places, for example, on HTC One it is located in the “Memory” section in the main menu.

3. The encryption process takes a long time, so it is important that your battery is fully charged. If the battery is not enough, you will receive a notification before encryption starts.
4. If everything is ready, click the button at the bottom of the screen "Encrypt Phone" or "Encrypt Tablet" (Encrypt Phone or Encrypt Tablet). Here your phone will ask for a password or PIN code, enter it to confirm. The warning message will appear again, click the “Encrypt Phone” button.
5. Your device will reboot and only after that the encryption will start. You will see an encryption progress indicator on the screen. While the encryption process is running, do not play with your phone and do not try to perform any actions, if you interrupt the encryption process, you can lose all or part of the data.
6. Once the encryption is over, the phone (tablet) will reboot and you will need to enter a password or PIN to decrypt all the data. After entering the password, all data will be decrypted and regular Android will boot.
PS: There you can also select files for encryption located on the SD card or encrypt the entire card.
