Muffled Calls and b&w instead of colour

Why are people not able to hear me properly? Muffled or sounds of interference on the line. 

Also, my phone keeps going black and white instead of colour. Background the sea black and white, Facebook black and white, photos black and white?

Camera is extremely sloooowww. Guys you need to fix these problems!!
