No I haven't experienced that stuff. It runs very smoothly.
I'd recommend resetting the android os from settings 》 backup&reset.
The next level is to completely reinstall the operating system using Samaung Kies (download straight from Samaung website). Install usb drivers from samsung site.
Once kies recognized your phone, run a full backup if you have anything you'd wish to back up, then reinstall/intitialize phone software.
