A:AnswerOver time it will, though not as bad as similar cases I've had like the Otterbox Symmetry, but it comes with a manufacturer's warranty that Best Buy fulfills in store. If it goes yellow just take it to the customer service desk in store with your receipt (or have them look it up if you are a Best Buy member) and tell them you'd just like to swap it under the manufacturer's warranty and they should be able to do it no problem.
A:AnswerIt’s very safe I’ve dropped it a couple times at that height and even a little higher by accident of course and nothing happened to my phone great protection to say the least
A:AnswerI bought the same case, and I would say the buttons on my unit are the easy to press. There might be a defect in your unit, so try returning it and buying another unit. Did you know you can try on cases at bestbuy? Thy if the other units are any different.
