Factory reset Android will securly wipe the data.

  That doesn't help if the phone is broken. My personal policy is to just keep all of my old devices (and hard drives, for that matter) forever.

    If you don't plan to repair them, wouldn't it make more sense to fully destroy them and dispose of them? I feel like you'd get quite a bit a junk hanging around after a while.

  a recent security research paper about android systems calling home stated that there are vendors whose factory reset in fact does not remove all user data from the phone.
