Every phone will have hiccups. My HTC ONE M8 was buttery smooth about 99.7% of the time with an occasional stutter. I love my Note 4, which is buttery smooth about 95%. I understand where the OP is coming from, we all pay a premium for our devices and we want them to work without fail. The lag is too much for some to accept and for the rest of us we are willing to live with a device that has the occasional hiccup. No one is wrong, it's your money, spend it as you see fit.
