I am using 2 android devices. A tablet with Android 9 with ODK Collect v1.27.2
I also have a phone with Android 6.0.1 with ODK Collect v1.27.1
When using ODK collect v1.27.2 and inputting time using this widget,
if I long press the minute part, I get a numeric keyboard that allows me to type in the minute. After I press ok, the minute part remains unchanged.
In ODK collect 1.27.1, this thing works as intended. In fact after you finish typing the hour part, the minute part gets focus.
In the latest version, after finishing the hour part, focus still remains on the hour part.
I also tested if things work differently if I used a different form. So I opened the demo form All widgets version 2019121101. I got the same results.
Interestingly, the time widget on my tablet contains a selector for AM/PM and the hour spinner maxes out at 12. Is it because the tablet is wider therefore it can afford the space needed to display the AM/PM part? On my phone, the AM/PM part is missing and you get a 24 hour spinner.
I hope this helps
