Hello! The screen on my GS4 is cracked pretty badly (pics coming), and I need to fix it. How can I tell whether I need to buy a $10 screen, or a $75+ digitizer kit?! The price difference is obviously significant, and even though I've been reading around for a while, I still can't figure out which way to go. My carrier is offering a $100 trade-in in on any device, as long as the screen is not cracked, and I reallyyy want to take advantage of this. Thank you all!
