During launching of coolpad dazen 1 in India, I bought this handset through online. For the first 2 months it was okay no other big problems than criticism of friends. In the beginning of 3rd month it became heated as an iron box and battery is slightly inflammatory.
Apart from this problem, it got viruses, if I switched on the internet continously add will be popped up we can’t make a call with internet on. Lastly it’s the worst phone I ever used. Sorry coolpad.
