Early this month, Samsung recalled every Galaxy Note 7 sold around the world over a manufacturing malfunction that causes some devices to overheat, catch fire and even explode. The recall affects 2.5 million phones globally, and Samsung has received at least 92 reports of batteries overheating in the US alone. The Consumer Product Safety Commission officially recalled the Galaxy Note 7 on September 15th. The Federal Aviation Administration and New York Metropolitan Transportation Authority have also warned against traveling with the phones.

Twenty-five percent of all potentially flammable phones in the US have already been exchanged, Samsung tells The Verge. Anyone with a Galaxy Note 7 will be able to tell if their device is safe via a green battery icon that shows up in the status bar, always-on display mode or power-off screen.
