WATCH: Samsung People Of Note. Capital FM Radio Presenter Christian Williams.

Christian Williams is a radio presenter with Capital FM in London and spends his days with celebrities and chart-busting musicians. So when he’s planning his next show, he needs a smart phone that makes scheduling all the celebs and hits he's cramming in as easy as possible.

Christian swears by his Samsung Galaxy Note 4, and uses it to tweet out to his 10,000 followers, schedule his radio shows and to make notes on the documents and call sheets he uses to keep his time on air entertaining.

We caught up with Christian in central London to see a day in the life of a radio star and how he personalises the Note 4.
