I encrypted the external SD card on my phone(Samsung A30). Firstly, I was able to directly access the SD card, once my phone was unlocked. That is, I was not required to enter a separate password, to access the SD Card! Then, when I connected(USB) my phone to my PC, I was able to access the files on the SD card, after unlocking the phone. What is the point of encrypting the the SD card, in the first place??? The only security that encryption has, is the password on the phone!!!
