Why do my GUI elements move when exported to Android?

When in unity while using an aspect ratio of 10:16 (Portrait) my GUI elements look the way they should…As soon as they are exported to a .apk and placed on an android device the GUI elements Move to a completely different spot and are skewed down? I have no clue why.

Android devices are not standardized. The aspect ratio and screen resolution of the device you are testing on is most likely drastically different then what you are developing for.
