Every time I said I was done with Samsung they always came out with an amazing phone right before my upgrade that made me decide to give them another try. After I got burned with my 6th samsung phone in a row I finally made the jump to htc and now after my 3rd htc phone I'm still more than completely happy with them. They've earned my business and support and I plan to stay with them for a while yet.
I usually upgrade every year just to keep current hardware, and my family fights over my old phones. I actually talked a friend into an S3 based on the reviews and his was a lemon. Never again.
My 4g lte is rock solid. It's really a great device.
Wife walks in...
Wife: Hey what are you doing?
me: Nada, phones finally rootable.
