So if you don't mind your screen with no Sony logo(ASF comes with that logo), you can choose a screen protector, better is the glass screen protector. Using a naked phone, the big problem is the dust or fingerprint on the screen which is really annoying. While you also can find an OEM ASF on witrigs.com(they do well on Sony accessories especially the ASF and cover flaps.) if you want.
It depends on your choice.
