2nd phone from the house of OnePlus. Users who loved OnePlus one, were expected a lot from this. Let us see: what its stores for you.
Build: Great build for 5.5 screen with matellic frame.
Display: IPS display, like I phone. I prefer.
OS: Here comes OxygenOS, still a child before big CM.
Battery: Average, more tweaks n optimization required.
Camera: its way better than OPO. High point of OPT.
Finger print scanner: Getting gr8 with OS updates.
Sound: will definately satisfy your deeds.
Lags: Had not come accross any, in last 3 months.
Heating: its surprize. It may or may not heat everytime.
So those some basic experiance of die heart fan of Carl & his products, from day 1.
If you want a phone, which you keep with for longer time: than just go for it.
If you are experimenting in nature and want best out of your hard cash, its not for you.
Writing this through OPT, only. My daily driver, till date.
