I wont reiterate the fabulous specification of the phone. Lets focus on the performance instead.
First of all if u own a one plus 3 then dont upgrade. The improvements are too few to consider this upgrade, especially considering the price difference.
This performs much better or at least at par to almost many flagship phones.
The network strength and response is quite good in this phone, even it performs faster internet in this device as well as the page loads faster.
Audio is much clearer and the headphone jack is amazing and music sound so good.
After sales service from amazon is very responsive and charges are pretty same as other devices.
Recommended flagship killer.
