This is a nice powerful phone by LG
Pros: 4 GB RAM, 64 GB ROM, 16 Mp camera, Dual Screen and many other cool features
Cons: Battery capacity is 3000 only, Overheating issues and unavailability of accessories in market
You can get a single and Dual SIM versions in the market for around 20k at OLX and around 30K in market. Better than LG 4 for sure. The new version LG V20 is a notch up with more RAM but is dearer on your pocket with around 45K
