There is a funny thing about hard drives/memory, for computers at least, not positive about phones but im pretty confident they dont act that much differently.
When you delete something, it does not erase it from the disk, it simply removes the listing. Similar to opening your file cabinet and removing labels but leaving files. It will stop the casual user or observer, but even best buy sells software to recover the files.
Its not gone till its overwritten, several times to be safe.
There are programs to do this for computers like "DBan" It fills your drive with random x's and o's formats, fills drive, formats, fills drive.... in order to destroy any chance of getting that info back.
Never give a computer with a hard drive away just because you "deleted" the info. Its still there if someone wants to look.
