I have been using this phone for quite a bit now.These are my pros and cons according to my usage and findings.
Pros-
5.15 inch 1080p vibrant display
very compact and easy to use and hold
Snapdragon 820 flagship prossesor
Rear 16 MP, f/2.0, phase detection autofocus, OIS(4-axis) and Front 4 MP, f/2.0, 1/3" sensor size camera
Huge 3000 mAh battery
cons-
Very slippery and pron to fingerprints
Only one vatiant available here in India
A bit over priced
In this Price bracket I would rather suggest you to go and buy OnePlus 3
