I want to buy a android smartphone, my budget is around 7,000rs.
I'm looking for good camera options.

is there any good smartphone releasing in india or already released - please let me know.

These three are new right now.. Google them to know more about them.

Moto E – 6,999.
Micromax Unite 2 – 6,813
Intex Aqua N15 – 6,090.

Moto E is ultimate winner with best quality and price balance.

However, Ausus Zenfone 4 looks tempting, with Intel dual core processor, it is surely a bang for buck and have a front camera also (0.3MP though) and prices less than Rs. 6000 . If I had to buy a phone now in this price range, would have settled for this one only.
