Hi, my roommate got this Galaxy Note 4 not too long ago. Went he first got it and connected to the wifi, no one could use the internet without lagging like crazy, I, for one, would get a sub 1mbps speed on speedtest when testing. I, naturally, QoS'd his phone because I thought the unit might me the problem. Then he sent back the phone to amazon because he got a SEA model. Few days later, he got his NA model and it still took pretty much all the bandwith. It would kill my internet even if he's doing nothing with his phone/not using it. I QoS'd him again, but he really wants the full potential of our internet as we both pay for it. Is there any reason the Note 4 does that? My OnePlus One doesn't seem to do this at all. Without QoS, my internet would just die the moment he gets home
