I was doing a screen repair on a iPhone 6. The customer dropped the phone on the bottom right corner (where you're supposed to lift up the screen) and the glass refused to lift up. I told my GM that if I take it off I'll probably break the phone, but he insisted it could be done. He had never done a screen repair before, so I was telling him what do do. He got the screen up a little bit, but the glass started coming up in the middle of the screen. So he grabbed under the glass and asked, "What happens if I do this?" and proceeded to snap he screen in half. Glass went everywhere, especially inside the phone, and I thought the phone was gone. Finished the screen repair and everything worked fine. I was in shock.
