I fix 20 to 30 phones a month , and known as the phone fixer around here, and i can tell you, they break with even the thick rubber cases, but they do offer more protection. I just finished one yesterday that was just in the guys pocket, with his keys. When he bend down, the keys must of applied to much pressure in one spot on the screen. Last week I did one where the girl had the Otterbox, but threw it at her boy friend, and it broke. My advice is, get an Iphone, the screens are 20% cost of the others. I've fixed some, and in two days, their back and I'm replacing them again.
