The date question type, usually displays a calendar widget below:
If you want to remove the calendar and only have spinners, you set the appearance as no-calendar.
However, when you are using Android v5.1.1, the date question type shows no calendar even when the appearance isn't set to no-calendar. (spinners)
I am using ODK Collect v1.18.2
To replicate, upload a form with two date questions, one with appearance set as no-calendar, the other without, like the one attached. Open your form on ODK Collect on android v5.1.1
This works as expected with Android v4.4.1 and v8.1.0.
