I bought k6 note on 03 December 2016. phone camera is awesome with doulby sound nvr effect not at all used 1/2 hour but heating problem is high then while charging also heating problem is very high in this phone and phone charger my opinion is if feel heating problem is not for us matter. its a good phone. but its battery is not great. in reality, it stay as standby for 24 hours. may be something wrong. I can’t believe it. talk is for 2 hours. its so bad, I am not impressed with it, s battery life
