Curious about what maintenance was required: looking for new programs? Installing new programs? Actual interaction with phones? Culling broken devices?
Restarting crashed apps (ads can load their own awful code), tapping periodic "are you still watching", swapping between apps during certain hours for more revenue
Basically, every day you reset any phones that were frozen. That would take 15 mins or so. Every now and then you would have to swap out a phone that was boot looping. Every now and then update the app. I would say 20-30 hours per month maybe?
