I bought this phone as a secondary phone, just to use with Jio Sim.
Better to buy this instead of JIO fi device which cost 2000, and can be used for internet only. Buy Cheap 4g+Volte enabled phone and do both Calling and 4g.
I got this phone for 3333 and this is the cheapest 4g+ Volte enabled phone in the market, its perfect secondary phone, Make a hotspot and use 4g anywhere.
Build quality - Nothing special - you get what you paid - nothing to complain
Battery - Reduced to 12% from 40 in 6 hours with continued usage of 4g Service.
Form Factor= quite small and cute phone with 4inch size.
Camera quality= doesnt matter to me as its just for internet and free calling - though specs says its 5MP with Flash, can capture okish images.
Front camera=:)
VFM= yes its a value for money phone, in 3333 one will get 4g+Volte Enabled Phone+ 5MP with Flash Camera+ Front Camera+ 1.5 Ghz Processor+ 1 GB Ram+ 8GB internal with 32 GB expendable+ Latest Andorid M.
Verdict= go for it if you just need a secondary phone and dont have much expectations.
