From my experience taking a phone away from a kid whose not interested isn't going to make them start working. There is no cell phone service inside our build space but the when the students don't want to work they always find ways to entertain themselves.

I do not view phone use(for not productive things)as a problem but rather a side effect of having unengaged students. Engaging those students is the way to increase productivity, not simply taking away their phones.
