I wanted to add my experience.... I am very careful about property like phones, cameras etc .... and I had an iphone4 for three years, never used a protective case, dropped it a few times on hard floors including stone and tiles, (arggg...) but it did not have a scratch on it. Tough little thing (but rubbish phone reception!).
In December I bought a new iphone6 ... it's an amazing piece of kit. Beautiful. Incredible functionality. Love it.
I was gutted when I dropped it after just a week onto a gravel driveway from about 30 inches. As I picked it up I did not expect the glass to have shattered... I imagined a nasty scratch. In fact, thankfully there was just a tiny scratch on the screen which you can only see in certain light. PHEW!
I have not dropped it again. At all.
THIS WEEK the phone was in the cup-holder of a hire car -once or twice knocking against the hard plastic surface. I stopped at a service area and checked my emails... and saw the phone now has a tiny chip (1-2mm) to the top left rounded corner of the screen, which has resulted in a 3mmx2mm area of damage under the glass, just BESIDE the chip.
I am as certain as I can be that this chip happened while it was in the plastic cup holder. I was not rally driving. It did not get bashed about - tho it did "fall over" against the hard plastic.
I don't blame anyone but myself. Accidents happen. Phones with glass fronts are sure to be a little fragile. They are not toys. They are amazing compared to the first mobile phones I used 30 years ago.
BUT I did come on this forum to log what happened and compare notes - in case there wis a pattern. I'll check back in a few weeks as I'm interested sharing knowledge.
Cheers
Phil
ps: petermac87 .... You keep telling people "don't drop it`'. You are not adding anything to the debate.
