Im sharing my experience about this k6 power. I had bought this phone six months ago from the retailer.
Looks are so stylish and handy, user friendly and easy to operate. But there is lot of mic problem. Sound quality is also not at all good. While gaming it gets heated too much of to hold. It takes so much time to get fully charged.
I suggest Lenovo to improve service and performance of the phone. I am not satisfied with this smartphone and also suggest you to think again before buying this phone.
