Space... did you have the October 14th update on your phone? From reading around on forums apparently people who are experiencing the lag on the note 4 are people who haven't got that update yet.
Im on EE and I haven't had that update either yet but apparently you can get it and flash it via ODIN.

Changing the rom to BTU won't unlock the phone IIRC.
mine is EE too, no lag.
Do you have the October updates though or is yours still September firmware like mine?
Can anyone confirm if the note 4 from mobiles.co.uk comes unlocked?
Can anyone confirm if the note 4 from mobiles.co.uk comes unlocked? I've gone for the £33 pm contract on o2 with 5gb and unltd mins and text, £99 for phone. I'm gonna keep the phone for myself and hopefully stick my 3 one plan sim inside if it's unlocked and my wife can use the O2 contract on her lg g2.
