Before I got the G2 I had a Galaxy S2. I LOVED that phone. I was sure that I was going to stick with Sammy for at least one more generation of phone. I was looking forward to getting the S4...but when I found out that it was difficult to get a Spark enabled S4 I became very turned off. I did some research and found out that the G2 was a damn good device. Learned about that hardware and found out that it had some of the best guts on the market. Since android OS is so malleable, I didn't really take into account software because if needed, I can change it how I see fit.
From day 1 I loved the G2. Such a great device. Great screen, great camera, great size, decent build quality, incredibly snappy device. As of right now, I'm planning on sticking with LG when I upgrade....but...that is 2 years away and I thought that same thing about sammy before too.
