Lenovo — some features are not working in the phone and can be rectified through software updates

I purchased a lenovo k8 note mobile phone through online from amazon.in commercial website. I booked it on[protected], which is available in amazon commercial website only. I got that phone delivered on[protected]. The lenovo company announced that, the phone was equipped with several latest features and that's why i bought it. Now i am facing problems with two important features. One is battery charging. The company announced that, the phone is having turbo charging, which means the phone would get charged in a short time. But it is not working. The phone is taking 6 to 7 hours for full charging. The other feature which is not working is screen mirroring. When we are selecting cast feature in the phone, it is not detecting any nearby devices, which means the feature is not working. I inquired and discussed about this problem with my friends, relatives and some other people like software professionals. They have confirmed that, these features are not working in this great phone and they said that it can be rectified through the software updates of the company. The company boasted this phone as a great phone. But it is not up to the mark. I therefore request the lenovo company to rectify the defects in the features through software updates immediately. My particulars are given below. Name: sangisetti venkata ramana murty, door no.1-15-17, sriramnagar, near bhanugudi center, kakinada-533003, east godavari district, andhra pradesh.
