I had a Galaxy S2 and hated the thing - it would never hold a charge and was constantly boot looping. Drove me nuts.
I have the same problem, if you want to buy a new cellphone, still Samsung or else?
I eventually wound up dropping AT&T for Sprint and got the HTC One, I love this phone it's so much better than any phone I've had so far. No boot loop problems, no charging problems, reads all my music, I can watch full screen 1080P video from content providers like Netflix and HBO Go, can't go wrong if you ask me! And the thin unibody construction is pretty awesome, every time I bring it out, my friends who have iPhones are constantly asking me about it.
