First off, I'm new here. I like what I see. Everyone seems helpful to one another. With that said. I cracked my glass. The LCD screen is fine. Just the outside glass. Now, with my insurance, I can get the phone replaced for $80. Or I can order the glass screen off ebay and do it myself. My question is; is there any kind of seal I'll have to break when replacing it? Like maybe causing dust to get behind the screen? And if so, is there something else I need to buy reseal it? Thanks in advance!
