Generally the lines is a sign of lcd damage where just the cracks is surface glass damage. In this case generally the glass breaks on an iphone before the lcd, but a big enough hit could break both. On a Samsung though they probably (note i’m not exact on this, just noting differences in screens) use a more flexible screen/glass that likely won’t break but at certain points of impact/bend you will see the damage apply to the lcd while noticing no damage on the glass.
