Android: Save button in hour registration not visible

Overview

When entering a description for a time card, the option to save the registration (checkmark icon in the right hand top corner) is not visible.

Cause

When accessing the description field of the time card registration, the Android keyboard moves in to place, therefor the screen scrolls-up. This is behaviour by design following the official Google guidelines. 

Solution

Click the keyboard icon to minimize the keyboard again, the top menu bar, with the option to save will come back in to view.
