I'm after a cheap Android phone for work. New options preferred but 2nd hand suggestions welcome. £100 max. We need it for screen sharing demo purposes so native Miracast support is the only requirement. All other features are irrelevant as it probably won't be used as a phone. Ideally we want to keep the cost down as much as possible, I can get a Lumia 830 with miracast for around £60 used - that's the target price. We could do with a phone running Android though as obviously far more people use Android. I've found the Galaxy S4 on ebay for around £100 but something with Marshmallow would be preferable. I'm struggling to find newer budget options that support miracast though, the Galaxy J1 looked viable but apparently does not support miracast. Suggestions?
