When the phone was launched, at that time it was a good option under twelve thousand, but when xiaomi launched note 3 that phone ruined k4’s market.
Still best sound in that range you can get. The camera is also good, ram is better than xiaomi note 3 which was launched earlier.
But at one place where it badly was beaten by xiaomi note 3 is the processor. Overall good phone, but xiaomi note 3 is a better option in this range.
