Lenovo k6 power is best mobile under 10k, I have been using from 3 months and till now nothing has happened to this. It has 3 amazing features like Fingerprint senser, Dolby Atmos sound, and 32Gb inbuilt memory under 19k. And you will get a lots of hidden features like quick camera, power saver mode and many more. And 4000mah battery will make your enjoyment double. and so far it has not hanged once. Peit is available online at Flipkart at Rs 9999. Personally I feel very satisfied with this mobile.
