Keep your screen hygienically clean for long with an antibacterial screen protector. An antibacterial screen protector has a special coating that ensures bacteria don't multiply on your screen. Thanks to this, you won't get stains as soon. Most new screen protectors have this special coating. Of course, a screen protector also protects your screen against scratches and bumps. Choose a plastic screen protector if you want a thin layer on your screen. A glass screen protector is a little bit thicker, but also offers better protection against bumps and deep scratches.
