Unity Remote and APK

The Upper picture is the one i got from Unity Remote, where I connect my phone to my comp. The second is when I build my game, and install the apk file onto my phone. Why does the size differs so much? I am using the UI canvas for those things (except for the sprite). Also, I set the sprite to a normal speed, and I liked its speed in unity remote. After I put it into apk, why does its speed became super fast? I am using update function for the movement of the sprite.

I have made a few Android apps, and I have noticed as well that the sprites will appear either stretched and/or bigger. All I can say is that the sizes will differ between both the build and the remote.
