iOS vs Android Secure Erasure

I’ve previously written about the difficulties recovering data from modern iOS devices. This new post by Avast(!?) shows it from another angle.  What happens when you sell an old device?

TL;DR

Because iOS uses hardware encryption on the main storage, recovery is almost impossible without the passcode. In contrast, Android phones (usually, by default) don’t encrypt the main storage. Also they allow external SD cards which may not be encrypted either. This means if an iPhone and an Android phone are sold or lost without being carefully erased, the iPhone will not easily give up the data but an android phone will. It also means if you forget your iPhone passcode you are unlikely to ever get the data back.
