'Factory reset' used to be much more obviously one setting, to the
extent that I'm not sure a non-tech-professional would be able to
do it effectively now. I wasn't able to find any setting that I
was confident would perform this for me, although I was using a
Samsung Bloatware Special.</blockquote>
<p>I've also added this article as well, as there are two ways to
factory reset, one via the settings and one via recovery mode. I
wonder if the second one would be available on that samsung. <br>
