Unity 4 remote iOS screen quished

I am developing a 2d app using Unity 4 and Unity 4 Remote. Development OS: Windows 8.1

When I run the app inside Unity, everything looks good. But when I connect an iPhone 5s using Unity Remote 4, the screen looks good but the sprites inside the screen are all squished. The game screen is set to 16:9 and the camera size is 4.49 (after trial and error).

Thanks in advance.
