My son in law just mentioned that the back is coming off his Key one. He says the the back cover has popped off in a few spots a couple of times and that he took it off to line it back up. It doesnt stay on that well.
Hmm. Nope. I dropped my KEYone onto asphalt (I freaked but all was well) and there was a small section that had popped up but it popped right back into place without a problem and has not recurred.
