Half resolution on IPhone 5c

Why my game has a half-resolution (568 x320) on ipohne 5c. Can I change it somewhere? I noticed something similar on Samsung tablet 12.2 pro (android).
but on the Samsung Galaxy 2 Galaxy 3 I have the full resolution. What does it depend?
I have only one device ios and I can not compare this with other iPhone.

Im sorry for my engish. I hope that you understood me well

Hey jacenty -

You will want to set the Device Profile to match the native resolution. Take a look at this documentation regarding the iOS r.MobileContentScaleFactor console variable,
