The dropdown field won't keep the selected option on an android phone using chrome

When using a dropdown the selected item in the dropdown is not populating the field.  The users are having to select the dropdown list a second time in order for the selected item to populate. 

I can replicate this with my own form so with your form. This is only happening when the dropdown field is required. The field jumps off or the popup options jump off when clicking, the selecting triggers the required field. 

I have now forwarded this thread to our developers for further review. If there are updates, you should know it through this thread.

For the meantime, you can change it to radio button field (for single selection).
