TRIM helps by telling the controller to stop monitoring deleted data, marking it for garbage collection (where the files are erased fully). How to Encrypt Data on My Android Phone 'I use my Android phone for work and it stores some sensitive business files. I decided just to reset it and hope for the best out of frustration. However, since Android 4.3, phones have included a protocol called TRIM. Since data is constantly written and deleted, the controller has to monitor an increasingly detailed map of the storage. When a file is deleted, the controller marks that space as “empty”, but doesn’t actually erase it. Unless you’ve removed file-based encryption from your device, any deleted data is impossible to recover regardless of what online services claim.Īnd, to make things worse, recovering data from an Android’s NAND flash memory is considerably more difficult than computer hard disk drives.Ī storage controller keeps note of all data on NAND flash storage. However, this also means that when a file is deleted, its encryption key is deleted alongside it, effectively erasing it entirely. This form of encryption uses different keys for different files, meaning they can be unlocked independently of each other. In the case of a factory reset, all files stored using full-disk encryption are erased and completely irretrievable.Īndroid 7.0 and up feature file-based encryption instead.

This form of encryption uses a single 128-bit Advanced Encryption Standard (AES) key which is securely stored on the device (protected by the user’s password).

So, while the data isn’t overwritten, it’s still technically retrievable – or it would be if the disc wasn’t encrypted.Īndroid 5.0 to Android 9 utilize full-disk encryption. The original data is then replaced when a new file is saved, overwriting it. Instead, the location of recently deleted files is marked as overwritable. In most phones (and storage devices), when files are deleted they aren’t actually erased.
