The phone is less than a year old, just call or take it back to Verizon and tell them it fell of when you tried to open/close it. Or tell them something else is wrong with it, and they will just swap it. You'll get a refurb if you are outside of your 30 days though.
Hello - I wanted to let everyone know that a company called RepairsUniverse.com has all kinds of high-quality, low-cost replacement parts available. Plus, when you order, you will also get a free repair guide and plastic pry tool. I was surprised by their fast shipping and the part I got for the Samsung Galaxy S worked perfectly
