Actually I did not. I went to my AT&T store in Friday and it was an absolute mad house due to the release of the new iPhones. All the reps were busy so I got plenty of time to actually use the G2 without impulse buying it.
The more I played with the phone, the less I liked it. I currently use a Note 2 so right of the bat, the G2 feels tiny. I actually liked this since it's easier to hold. Not a fan of the back buttons but I only used then for 30 mins or so.The screen is amazing, no doubt about it. The phone itself seems very cheap. My note 2 isn't a premium phone by any means but it has taken a beating due to my clumsiness. It's banged up but nothing more than scratches on the exterior. The G2 feels much more fragile and I just...slippery. I didn't like it.
As far as software is concerned, I prefer stock Android but I've modded my note 2 to look Jellybean even though it's still a touchwiz Rom (for the camera, spen, and better Bluetooth support). I've already been reading the G2 is having Bluetooth issues and I'm weary of LG's support and upgrade plan though Samsung isn't better in that regard either.
I guess I'm going with the Note 3 but like most people, the phone I really want doesn't exist yet.
