Nokia Lumia 730 is the worst phone I have ever used. Although the phone looks very stylish with sharp edges and good camera quality with carl zeis optics lens supported but it always hangs and heating problem is common. As compared to andriod phones very few apps are supported by lumia. Bluetooth connectivity with other andriod phones is also a big drawback of this phone. Sometime the network bar disappears also. Its OS is also so complicated for users and its a typical phone for users. Price is also high because in the same pricing we have various other smartphones available in the market, so never go for this phone.
