I was presently using this smartphone for 12 months, I buy this smartphone on flash sale on flipkart. At first it works like a boss of the smartphones at a affordable price of 10, 000. But after using it for 4 months these are the problems I have faced 1) display was damaged instead of using very neatly. 2) battery backup -3000 mah but wotk like 2000 mah. 3) hanging issue while browsing. 4) software issues like notification pannel not responding properly 5) it has come with dolby atmos sound feature but it doesn’t works at all. So my final suggestion is to take redmi note 3, DONT GO FOR LENOVO K3 NOTE
