Samsung’s latest flagship smartphone, the Galaxy Note 7, is prone to exploding. Once the flaw was discovered, Note 7 sales were halted, but that move only came after millions of devices were shipped to consumers and retail outlets. Samsung is now faced with recalling millions of potentially dangerous devices, and it’s up to consumers to identify potentially explosive devices from the non-explosive ones. Communicating this to every Note 7 customer is turning into a challenge, as a few days after the recall a Note 7 apparently burned down a customer’s Jeep.

If you’re shopping for a Galaxy Note 7, Samsung has announced a new bar code label for the box will let you know your new device is not explosive. The new packaging is shown above, which Samsung says has “clear identifiers on the box; a small black square on the white bar code label along with a white sticker with a blue letter ‘S’.

That new packaging requires you to have the box handy, though. If you want to know if an unboxed Galaxy Note 7 has been repaired, things are a little more complicated. Samsung says that next Tuesday, September 13, the company will launch online IMEI database that will let customers type in their device’s unique ID and lookup if it has been fixed. On the Galaxy Note 7, the IMEI number is located on the bottom of the device next to the USB port. Customers can also call Samsung customer service to have their device identified.
