XpressFix charges 169. Will be posting video on this repair soon - it's kind of choppy right now and the last one I posted I wasn't exactly proud of (I wanted a cleaner edit but it did the job - the presentation that is). Oldturkey saw my Galaxy S3 vid, I think, and the S4 is similar but a bit more difficult. Definitely not a DYI but this is a DIY site so I'm inclined to believe that anyone who sees this vid will get some value.
Yes the glass can be separated from the LCD on the Apple repair - iPhone 5 screen replacement. I am going to prepare a video this week or next because it is much cheaper this method. It does take a lot longer to diffuse the glass from the LCD but it can be done. This is a DIY site so I'm assuming I will convince some of you to try it. I own XpressFix iPhone Repair so there will be a video posted in the blog within 2 weeks.
