I had purchased Gionee Elife E6 black colour phone at Rs 20000 form snapdeal and I am happy with it.
The mobile has a quad core processor. and never hangs. runs smoothly. 1.5 ghz speed. The back camera is of 13 mp with flash and its quite good. gives good photographs in good light. but front camera is not so good. the front camera is of 5 mp.
Its a android based smartphone. and has android jellybean version.well now days kitkat is all where. will be happy is its will come kitkat out of the box.
The screen is of 5.0 inch . and good. as it fits perfectly in pocket. and its a dual sim phone. Battery backup is its the biggest positive. A very long battery life. runs one day easily even after heavy usage.
Has 2 gb ram. umm. okay. but now many smartphones are came with 3 gb in market. Speakers are nice. sound are very clear and loud enough.
Verdict- if anyone wants a smartphone around 20000, then its a great smartphone you should look to.
