Walked into the verizon by me (actual verizon, not an authorized seller or anything like that) and got it in January.
Rarely have I had any issues with it. Its rebooted on me a few times, but only when I've either done something to it or installed something new/experimental. Mic cut out on me 1 time in a phone call. No reboot, redialed and all was well with the world.
It seems the majority of the Korean made ones are perfect/nearly perfect. sweet! =D
No issues with the hardware at all. The software has some faults, but they are minor. I recently ROM'd the phone and eliminated the softkeys. Now there is some burn-in present on the screen where they used to sit, but it's to be expected and it's hardly noticeable. In fact, no one can see it except for me.
Korea, 11.11, Christmas present. Minor issues, like inconsistent wi fi (works great at work, but have to just turn it off at home). also gave up on spotty 4g, set to 3g only. Battery life (2100 mah) ok, makes it through the day with moderate usage. Otherwise, it's a beautiful phone, best hand held computer in the world.
