Nor is the ban on the use of mobile phones.
I think pretty much every airport has "no photography" signs in security areas. From my experiences this year, MAG airports are the only ones that extend this to an outright ban on use of mobile phones anywhere and enforce it with people shouting at you. Others are pragmatic and recognise that if your phone is pointing at the floor and you are typing a text or e-mail or something, you are unlikely to be a security threat.
Above comments were made from my own experience of flying through 22 UK airports this year. That clearly doesn't make it a definitive list.
