I've had this phone for 2 weeks now, came from a Huawei mate 9. This is my first one plus & so far it's just "OK".
Things I dig:
Fast battery charge
No lag / fast/ smooth
Things that are just ok:
Battery life
Mute switch - unusual option (although I think it's backwards - down is on?)
Things I don't dig:
Weather widget does not update to your location - only shows "home"
Volume button directly opposite of power button - I can't tell you how many screen shots I've already taken, turning the phone off.
Volume rocker controls media volume by default. With no apps running, the volume should control/change ringer volume.
Finger print sensor is too low.
No notification led.
