When Samsung kicked off the global recall for the Note 7, the company said that it found over 35 reported instances of battery malfunctions around the globe. That number has increased to more than 70 in the U.S., according to a new report published by the Canadian government.

Samsung asked customers in the U.S. to voluntarily turn in their Note 7 earlier this month, and the U.S. Consumer Product Safety Commission is now getting involved in issuing a complete recall of the phone.

The FAA and Transport Canada is asking travelers to power down their Note 7s and not use them in-flight, and to avoid stowing them in checked baggage.

Meanwhile, the Canadian government's Health Canada website has detailed information on the recall, including affected SKUs and model codes. The agency is coordinating with Samsung over a mandatory recall of the 21,953 Note 7 units sold in the country, and is advising customers to immediately power off their phones. The agency also found a single instance of the Note 7 overheating in the country, with no injuries reported.

All Note 7 customers in Canada are eligible to receive a new unit once it becomes available, or opt for a Galaxy S7 or S7 edge. There's a dedicated page for customers looking to get their Note 7 exchanged, as well as a toll-free number for further assistance: 1-800-517-3507.
