InFocus — infocus turbo 5 poor services

I seen many problems in my infocus turbo5 within 16 days of purchase and still faces these problems even after reset my phones.in my whole life i never seen a worst phone like infocus turbo 5. Its a money waste phone. Too much laging
Software are not working properly. App shows error while running. Infocus just make money and cheated the people. My main problems are listed below.
1. Very poor battery service
2. Flashlight open automatically without my concern
3. Some apps shows error while i using these apps. And they are those apps which are inbuilt in phone.
4. Softkeys works very poor. Sometimes they not perform any task.
5. Sometimes camera is inverted and there is no option of rear camera..
Please solve my problems other wise i complaint a file in court againt infocus
