Moto G5 Plus is the best cost-effective phone available as of now.
I got myself this phone 2 weeks back for 16K, from amazon and the delivery was done in 5 days.
The phone is fully metallic with perfect, comfortable edges and full high definition LCD display. Screen is protected with Gorilla Glass 3.
I would also like to highlight some features I found cool while using and which are not much known;
The phone is able to run 2 apps simultaneously.
There is a water protective coat to protect from splashes.
Quick charge is supported.
Can record slowmotion videos.
And most importantly, No major complaints heard about the phone till date.
I would recommend for those who are in search of the perfect phone.
