Your iPhone will work just fine if you put scratches all over its body. But its screen is much different. It is tough to use an iPhone with a damaged screen. Getting your hands on a screen protector such as the ones by ClearPlex is not a bad idea. These are not only clear touchscreen protectors but can handle high speed impacts. ClearPlex’s screen protector will increase break resistance up to 39%. It costs you $13.99.
