ANother to add to the list here, always put a screen protector and phone in a case when i get them new. And also always usually bought Apple iphones, and never had a problem with broken screens or broken lenses. Yet this S5 within a month has a crack right through the middle of the lens..... the thing hasnt been out of my pocket, just like i kept the iphone 3,4,4s and 5 before it..
Guessing its going to be the auld slopy shoulders from Samsung for this issue then...
case - Spigen Slim armor
screen protector- Zagg Extreme protection invisible shield
