Look - its not a phone, its a sketch pad. Great to see so many art students at this exhibition today - all, well 95%, absorbed in sketching rather than looking at their phones. 

And its a strange exhibition that I didnt quite get.  Still, the French Impressionist show more than compensated with lots of fun choosing which painting we would steal from each room. And the students in exile in the extra look like they enjoyed it too.
