LYF water 7 this device is totally bad quality waste of money. This device battery backup is lessthan 30% during net connection or when play video or game. Sound quality also bad. Camera quality make me laugh it image quality is totally bad. Face detection not work properly. Mobile hit when put in charging and overall the system of this device is diffcult cant understand how it work. I waste money for 4G connectivity. Nothing in this device for this price.
