I've had my Droid DNA for a few days without a case now. I know I will be dropping it from about three feet on the floor from time to time. I'm not planning on using a screen protector with it and I don't want a case that has a built in screen protector. I've heard that, because of the edge to edge glass, it breaks easily when dropped. Is it safe for me to use it without a case? I really want to protect it well because I don't have insurance on it, but my budget for a case is $20. Also, this phone is already too big to fit in my pocket normally, so I don't want it to get much bulkier. What is the thinnest case that will protect it from falls under $20 (can be used and from sites like eBay)? Some cases I have looked at are the Diztronic, Ballistic SG, S-Line, and Body Glove Dropsuit. Which of these will give enough protection that I can drop my phone from time to time with no damage? Thanks in advance everyone!
