I really feel that Sony Xperia M4 Aqua dual phone uses fake advertising as this phone doesn’t work well. when used in water environment the phone is made up of low quality material and is not durable. it is very slow and heavy and also heats up the phone is very expensive than its other competitors which are better than this phone. the camera is also not that good and the touch screen is very bad .the display on this phone is not very good .after getting wet this phone becomes more useless.
