Help Just bought a used Galaxy s4 - should I factor reset?

[netrate]

I just purchased a galaxy s4 (the camera works intermittently apparently). I was wondering do most people factor reset a phone when they get it? Does this help it - for example, I know that a reinstall of windows on a computer helps it work faster because it eliminates the cluttered filing systems. Does the same hold for phones?

If I bought a used phone from someone I didn't know... then yes, the first thing I'd do (before I handed over the cash) would be a factory reset.

It was a friend, he told me in advance the camera was wonky. I didn't know since it is older if factory reset might actually not be a good think because of updates etc. So you are saying yes either way ? and lastly how do I factory reset?

I would think a Factory Reset is your best option, you don't know what kind of customization the previous owner did (good or bad). It might even restore the camera's functionality. But taking over a used phone that's as 'clean' as possible to start with is more optimal, that way you know if something is 'odd' it's because of a change you made and not something that's from its previous owner. Also, as you start using your 'new' phone more you don't want to mess with a mix of your and his files.
