This is the best phone in this price segment.I have been using this awesome phone for about 5 months now and there is no lag what so ever.my usage is very heavy. This phone has served me soo good.the camera is also the best in class .the primary camera is actually better than iPhone 6 .the battery life is amazing .the phone can run all day with heavy usage.The phone could have come with company earphones which is a drawback , we have spend extra bucks on earphones.other than that this is the best phone that you can by for that money.There is no heating problem also.Getting the phone is bit of a struggle because of the demand. I was lucky to get it.
