The Federal Aviation Administration is telling passengers not to use their Samsung Galaxy Note 7 phones aboard airplanes following recent battery explosions. Airlines are warning passengers not to turn on their phones while in flight in response.

“The Federal Aviation Administration strongly advises passengers not to turn on or charge these devices on board aircraft and not to stow them in any checked baggage,” said a statement put out by the agency.

Samsung announced Sept. 2, that it ceased all sales of the Galaxy Note 7 after several reports of exploding batteries on airplanes. Samsung counted 35 reports of battery cell problems around the world and said it will offer free Galaxy Note 7 replacements to anyone who owns one in response to the issues.

“We are aware of the Federal Aviation Administration’s statement about the Galaxy Note 7,” Samsung said. “Consumer safety and peace of mind are our top priority. We plan to expedite new shipments of Galaxy Note 7 starting from this week in order to alleviate any safety concerns and reduce any inconvenience for our customers.”
