I have been using this phone for almost seven months and trust me this is the best phone under 20k.And I mean it.
Phone is buttery smooth.thanks to the stable EXYNOS processor that is used in high-end phones.
I have installed over 100 apps and not even once it has slowed down.
2 gb of ram lets you run multiple apps and switch between them without any lag.
Camera quality is best in class.5MP front camera with front flash makes selfies awesome.
It has a nice metal frame and a plastic removable back with metal finish.
The phone is really sleek and gives a premium feel even though it has a plastic back.
Both hardware and software are very reliable.
Sound quality is good but not upto the mark.
Hence, i would conclude by saying that it is a good value for money.
