Chinese smartphone company Oppo introduced two new technologies in the Shanghai Mobile World Congress. Among them are a mesh talk and the other is screen camera technology. The company claims that through the Mesh Talk technology, two OPPO phone users will be able to talk and send messages without any mobile network, WiFi or Bluetooth within three kilometers radius. This technology will not affect battery performance. The company said that this technology will also work well in the crowded areas. Oppo also introduced these screen camera features apart from this. The camera came in the phone so far out of the screen.
