My friend has the same one and I’m using one plus 5 for several weeks
The phone is nice and slim, but veery slippery!
Very fast, no heating or lags
Holding the phone in portrait mode I usually cover speaker, that’s bad
The same for antennas. I feel because antennas on the sides, wifi signal drops holding in portrait mode. Wifi is better than on iPhone but worse than lg
Camera’s portrait mode sometimes misses and parts of the pictures are in focus when should be blurred and vice versa
Battery life looks solid. Can hold up to 6 days with minimal usage(wifi only)
The most annoying thing - volume button is directly opposite to power button, and when you try to adjust volume you squeeze the phone and turn off the screen by pressing on power button! Hate this.
