The answer is simple. Don't go looking for anything, just get it and enjoy it. Don't believe all of the issues here as we all exaggerate. Just like any device forum people don't talk about how well there device works, but when one small thing comes up on one device out of millions people tend to freak out. The only reason people are nit-picking this device apart is because we don't have root. Without root the only thing we can do is talk about the weather, and turn specs of tiny dust into a major castrophe. My sister just got this phone last week and she loves it. She didn't say "Hey the screen is AUO and not a Sharp", she didn't say "the wifi signal drops when I bear hug it". Nope, she loves it and said it's the best phone she ever had, and I agree with her.
Don't put it under a microscope and just enjoy it. If your phone is defective you can always exchange it.
