My glass broke, not sure how, but its cracked from side to bot. Screen seems perfect but I ordered a new HTC glass. Then I've read tutorials on how to change it and it seems too hard for me to do so. My brother thought it was going to be easier than an iPhone but then he looked and I guess i need to open it and to do so much things. Is it that hard? Should I take it to a shop or something? What would you do?
