Both vector and docubook were based on the wikipedia model, as were others, and these were generally not functional on a phone. Or only marginally so, see for instance monobook.

All the tests were done on a Google Pixel 2XL. The criteria for templates that are designed for phones basically came down to whether the template was in fact designed for use on phones. This means functional in portrait mode, which includes:

1. Readablility
2. Functional navigation

There were some templates that worked in landscape mode but not portrait mode, that is they had not been specifically designed for phones but by accident of design worked in landcape.
