Or you consider flashing a sammy custom rom, since the 4.3 sammy update is far away from perfect. But there are some devs which improved the 4.3 firmware. So I could recommend you for instance NeatRom a lot over the original firmware, but see for yourself. As I said many custom roms based on the official stock sammy 4.3 are actually a lot more stable, smoother and battery friendly. Good luck
