No smartphone can do what the LG K7i can, because it can chase away mosquitoes with sounds in the ultrasonic range. The rest of the equipment for the smartphone fly swatter would certainly have a hard time on the local market. A 5-inch 720p display, a 1,1 GHz quad-core chip, 2 GB of RAM and cameras with 8 and 5 megapixels are not exactly the best. At least there is a fingerprint sensor on the back of the LG K7i for convenient unlocking of the smartphone.
The smartphone wants to drive away the annoying pests with another, hopefully not annoying, amount of money. The LG K7i has a loudspeaker on the back that emits sounds in the ultrasonic range, which are supposed to drive mosquitos away from the smartphone. The whole thing sounds like an April Fool's joke, of course, but it has an initial background. There are numerous tropical and subtropical areas where mosquitos can transmit dangerous diseases, not least malaria. A smartphone like the LG K7i could be of great help here - if the ultrasonic loudspeaker is actually more than a marketing gimmick.
