NEW YORK — Samsung Electronics is launching a PR agency review for its mobile business, which is currently handled by key agency partner Edelman, Holmes Report has learned.

Sources said the South Korean electronics giant is in the process of inviting agencies to participate in the pitch.

The move comes nearly three years after Samsung moved its mobile business to Edelman, which also handles the company’s corporate communications, from previous partner FleishmanHillard. At that time, the assignment was estimated to be worth $2m.

The search also comes as Samsung tries to boost its mobile business with new products following a slump in sales.

Although still the world’s largest smartphone seller, with a roughly 20% share of the markets, Samsung’s business has been on a  downturn much of this year.

In November, IDC’s Worldwide Quarterly Mobile Phone Tracker reported that Samsung’s smartphone shipments were down roughly 13% to 72.2 million units in Q3 2018. The company also reported a Q2 slump, which it pegged largely to slow sales for its Galaxy S9 smartphone.

Neither Samsung nor Edelman responded to request for comment.
