Pros:
Great price for a 5.5" phone with dual standby sim.
Extremely light to hold(140 gm Vs 185 gm for Redmi Note 4G). You can really feel the difference. Also very thin again as compared to Redmi note and easy to hold. The profile is very sleek though orthodox.
Great UI. Intuitive and very similar to other Android phones. Pull down settings. Slightly improved over MiUI 6.
Decent camera.
Dolby sound is great. Better than Redmi Note which was difficult to hear in open areas.
Shows%age charging information while charging including time remaining to charge 100%. Battery seems to be lasting a full day.
Good display - even to watch HD movies.
2GB RAM - no noticable lag. However I have not played any heavy games so far.
OTG supported unlike Honor 4X. USB device shows as External Storage 1.
Call quality is very good.
Multitasking is great. All apps are in the background ready to use.
Cons are mostly minor and irritants rather than issues:
Not many options for back covers. Had to buy a transparent cover on eBay.
USB connection is on the top rather than bottom. Looks awkward.
No backlit buttons unlike Redmi Note.
Only 8 GB onboard memory. However it can take 32 GB card.
Only one Sim is LTE / 4G enabled. Second Sim is 2G.
I would strongly suggest this phone over any other budget Dual Sim available today. No regrets!
