> I don't understand how wear leveling makes deniability impossible. You just have to overwrite sectors in the false partition at the same rate as ones in the true partition. Since both the true and false partitions are encrypted, their contents are mathematically indistinguishable from randomness when viewed without the decryption key.
With deniability, isn't the idea that you would have unlocked the false partition to show that you have nothing on your phone, therefore it's not encrypted?
