This is the best smartphone I have seen with such a low budget. It has metallic body and camera quality is far beyond excellence. The look is very similar to iPhone and battery backup is good lasting for around 6 hours if you use internet. It lasts for a complete day without any battery issues.
It has 16gb internal storage which is sufficient and 2gb RAM. Also it comes into various colors but my favourite is gold.
It is a highly recommended phone within a budget of Rs6000 only.
