Fit game on my phone

hi guys

i have a cheap Alcatel 1c running on this resolution 480x960 pixels
i have made a title screen and started a level on my game.

i installed unity remote and got my phone working with it over some time.
but when i do a build and install it on my phone it doesnt display right looks a bit small, there
are borders. and buttons are not where they should be.

so is there a point to using remote at all, because as i was running on remote it all looked good, till i built it and installed it on my phone.

i tried to change the resolution on unity but couldnt find where to do this
tried prokect settings/player but there are no resolution settings i can see.

any help would be appreciated

 

please somebody
