Yu Yureka Black is the which, on paper, able to attract customers but only good specification is not enough, it has to perform well which Yu Yureka Black fails. On paper it contains 1.4 GHz octa Core processor and contains Quallcom Snapdragon 430 SoC Chipset which is little bit stronger than that of Lenovo K6 Power. But both perform exactly same and there is no difference.
It contains 4 GB RAM which is very good and out of expectation. Display is also very good and it contains 1080p HD display. But company cuts this in its battery and some other small features. It contains 3000 mAh Lion Battery which is little bit low and hardly runs a day. Camera quality is also not very good but average which acceptable at this pry segment.
