I have the Korean LG Optimus LTE 2. It is great. I got it June 6th. Pretty awesome for my first android phone.
Do i have any complaints? Not really. I've had trouble with some apps randomly having image uploading problems. The phone rocks. Quick. Responsive. I'm not a gamer so I don't need battery eating four core phone.
Multitasking is easy. Yes, I have 2GB of RAM. About a GIG is always used to preload the OS and seemingly popular apps. Every app starts quick.
I can't complain.
Issues I've had.... This is an LG phone, but I'm using SK Telecom service in Korea. As such, I can't use LG's IPTV-HD streaming ability. I know SK will roll out their own HD-IPTV ability soon enough.
Secondly, when I got the phone I could connect to SK wife hot spots automatically with WiFi on. After a few days, something went wrong. A/S decided to reinstall thinking some app messed up the ability. Well, a reinstall worked. By the way, South Korean a/s service is available everywhere and rocks for the most part.
The other issue I ran into is ubersocial and instagram refusing to upload images. these problems haven't been consistent. I think forcing gpu rendering in the "development" menu problem was responsible.
I highly recommend the phone. The screen rocks. If you are going to be some gamer or running a busy webserver off your phone then maybe you will want the four core Samsung Galaxy SIII, but for what I need, this thing rocks.
