2D game is blurry when previewed on mobile and not in Unity

This is what it looks like when I click play and on my iPhone 5S,

and this is what it looks like on my computer and within Unity 5.


I've tried, pixel perfect, making the height and width high and lowering the scale to 0.1, un-checking min maps, changing it to point, changing it to true colour etc... tried everything.

 

if the game is 2D make sure the Sprite sheet is set too TrueColor also if the size of your sprite sheet is lets 1024x1024 then set size too 1024, don't set it less than the size of the image is.

this should help..
