Help Encrypted photos on external SD card still retrievable after formatting

[CMomo]

Hey All,

I encrypted my external microSD card on my Samsung Galaxy S4 (Android Version 4.4.2) and then I formatted it. After formatting it, I ran it through a recovery program and realised that the encrypted photos were accessible for recovery. As a second test, I took a new photo, encrypted my external microSD card, formatted the card, then ran it through the recovery program and found that the new photo I took was also retrievable.

How come encrypted photos can still be retrieved? And is it worth it encrypting my files if they're so easily accessed like this?

Thanks!

What program are you using to recover the pictures? I accidentally formatted my SD card and I can't recover the encrypted files.

Thank you

CardRecovery, but I'm just using the free version. You need to pay to use it fully I think. There are other recovery programs you can use though such as Recuva

Edit: Recuva is free, whilst CardRecovery requires payment
