I've tried this on a few Android phones and what did I learn? It appears we have to go to the product manual to figure out how to clear EVERYTHING. A "factory reset" appears to not do a wipe on many models.

So make it easy for everyone and supply a link to the product manual. You own this so my bet is you have that handy.
