I did a quick search and I couldn't find any threads on this so I thought I'd start one.
Before selling my old phones I'd wipe the memory by doing a factory data reset for security reasons, I mean who wants their stuff snooped on by the new owner right?
Being a little suss that the whole process only takes a few minutes I did a quick search and found this.
A group at Avast bought a bunch of phones from eBay and recovered data (including some guy's schlong-selfy) that was supposed to have been deleted. According to them "When a file is deleted [through a factory data reset or by other means], the operating system just deletes the pointers corresponding to that file and marks the space that will be overwritten when another file is stored. [It doesn't actually delete the data]" Avast is saying that they have the software that can permanently delete your junk, but apparently there are a few other methods too...
one) Before you do a factory reset, encrypt your phone first (then go ahead with the reset as normal). This will effectively throw away the encryption key making it harder for the spooks to get your data
or two) if you've already gone ahead with the data reset, you can try to fill your device with benign data to overwrite your files
My question is has anyone tried any of the software out there or do you think the above mentioned would actually work?
Thanks
Edit: not sure if this is the right section! ><
