The warning comes just a month after the recall of over 50,000 phones in Australia.
In a statement, Samsung said, "Consumers' safety remains our top priority. We will ask all carrier and retail partners globally to stop sales and exchanges of the Galaxy Note7 while the investigation is taking place."
Samsung has asked all retailers across the globe to stop selling and exchanging its Galaxy Note7 smartphone, and has instructed all owners of the phone to power it off and seek a refund or replacement.
In Australia, many retailers and telcos had already stopped selling or replacing Note7s. Vodafone has said it will replace customers' Note7 with a Samsung Galaxy S7 Edge. Telstra and Optus also indicated that they would swap the handset for an alternative phone.
