bought the noise colorfit pulse grand ( jet black)smatch watch recently. In the starting days, it worked so efficiently , but it's not working now. I can't even on the watch. I thought the watch is not power on due to low charging and I charged it. But still, it is powered off. It is not even showing the display screen also. It hadn’t even been 2 weeks since I bought my watch. As there is a warranty I need to exchange my product with another one of the same product with the same colour. please troubleshoot my problem as soon as possible.
