I registered to come here and hopefully answer for someone the questions I had about this case before I bought it(and for those keeping track, serial number 59****, all black):
Q: Does the screen protector portion of the case bubble up at all?
A: No. There is no bubbling. There are no air pockets. There is no feeling the protector moving beneath my fingers. There is no sound of air escaping beneath my fingers. Maybe you can tell that the protector moves if you push on it REALLY hard with your fingers - but then again, of course it would in that case. For normal use, you don't really notice it's there at all.
Q: Are certain parts of the screen less responsive than others with the case on?
A: No. I have noticed absolutely zero dead spots in terms of sensitivity. Everywhere seems very responsive. Everywhere is as responsive as the phone is out of the case. No areas need to be hit more than once to get a response.
Q: Are there newton rings on the screen protector?
A: Yes. Let me tell you when I see them - when my phone is not in use sitting on my desk. When the phone is in my hand with the case on do I notice them? Nope. Unless you are care about how the screen protector looks when you're not using the phone I see this as an absolute none issue.
Q: Can people hear me when I talk on the phone?
A: Yes. Everyone says loud and clear. They don't sound muffled. Quite a relief, actually. 40 min phone call this evening, everything sounded great.
Q: Does the case distort music from the phone?
A: No. When do people use their phone to listen to music anyway? I tested this specifically for this post. Sounds fine. But really, why do people care about this?
Q: Is there a weird buzzing while talking on the phone?
A: No. Everything sounds perfectly fine.
Q: what is the quality of speaker phone with the case on?
A: Don't know, didn't test. I'll update with that information later on.
Q: Does the case feel cheaply made?
A: No. Exactly what I expected actually. Were people expecting really heavy stainless steel? It actually feels very light and sturdy in my hand. Love it.
Q: Is the home button or other buttons hard to use/decreased sensitivity?
A: Everything works and responds just fine. Also a relief.
Q: Is everything water tight?
A: Haven't tested. I'll do that later. Currently not a lot of water too motivate me to take the time to test that (going to school in AZ and spend all of my time in the library)
Q: Does it feel bulky?
A: No
Q: Does it fit well in a pocket?
A: Yes. I couldn't tell you what it's like wearing girl jeans, since I'm a dude and junk
Q: Do I work for lifeproof/am I a PR guy
A: No.
Bottom line: Great case. Expensive, but it's water proof. My reason for getting it - I wanted something to protect the phone, especially the screen, from anything. I wanted a case that would protect my phone so that I could just throw it into my bag without thinking twice while getting out in the mountains or traveling somewhere. Something to give me the confidence to leave it in my jacket pocket when on snow. Something to tuck into my trail running shorts and not worry about dirt and sweat and water.
Allegedly there are lots of knock offs you can buy online. I bought my in store from bestbuy. Just makes sure you buy from an authorized dealer so you know you are getting there real thing. I think a lot of peoples problems with the case either stem from them installing it wrong (it's very simple, really - but some people have had all their problems disappear on reinstall), they bought a knock off, they care about stupid things that don't matter at all (netwon rings? Seriously, find something worthwhile to care about in life)
TL;dr: Perfectly functional case for the person who is planning to bump up their phone and doesn't want to worry about it getting damaged.
Ask me whatever you want to know about the case and I'll test it for you. I'll check back in a couple of weeks.
