I dunno bout you guys but ill never buy samsung again, every samsung phone i had always was laggy and glitchy and software just did not go with the hardware, even on my damn $3000 samsung led 3d tv software sucks on it. Terrible, my SG3 sucked, home button laggy, going from one thing to another always laggy i swapped phones out 3 times still had speaker issue with the damn thing, ugh so over samsung. I dont know about the people having battery issue but mine works perfect i constantly use it and never have battery issue
