Recently I bought motog4 Plus mobile from amazon.My Experience is good with motog4 plus mobile.
Each and every feature working fine in motog4 plus.If we talk about sound quality then it provide one speaker on front with good quality.Camera is also good.It provide 16 megapixel back camera and 5MP front camera.Picture quality is good of both front and back.
Its very simple to use and also provide some extra facility that make more reliable to use like hand shaking facility.it turns on camera when you move your hand two times.
If you shake Phone Up down its turn on back flash. and so on feature with moto g4plus.
so my suggestion is if you invest 14000 then you can think about moto g4 plus.
