Since reports first broke about battery explosions involving Samsung's Galaxy Note 7, it has been a little confusing for smartphone owners to figure out what to do with their faulty phones.

Now that Samsung has issued an official recall through the U.S. Consumer Product Safety Commission that affects 1 million U.S. phones, we have a clear answer: If you have a Note 7, you should check immediately whether you should turn it in.

To do so, go to Samsung's website — samsung.com — where you will be able to check whether your phone is included in the recall. The site will ask you for your IMEI (International Mobile Equipment Identity) number. In a best-case scenario, this will be listed either on a sticker on the back of your phone or on your phone's box. Otherwise, you can find it by turning on the phone and heading into the settings menu. Navigate to "General Management," then "Status" and "IMEI information." It is a 15-digit number.

Once you enter the number, the site will check whether your device has the battery that's prompting this recall. Unfortunately, according to the Consumer Product Safety Commission, 97 percent of Note 7 phones sold in the United States are part of the recall — so there's a very good chance that your phone will have that battery. If it does, that entitles you to either a replacement phone or a full refund.

How do you get that done? Here's the skinny, taken straight from the CPSC's own website:

Contact the wireless carrier, retail outlet or Samsung.com where you purchased your device to receive free of charge a new Galaxy Note 7 with a different battery, a refund or a new replacement device.  Go to www.samsung.com for more details.

 

Target, which was also selling the devices before halting sales earlier this month, did not immediately respond to a request for comment on what its customers should do.

If you can't immediately return your Galaxy Note 7, you should turn it off immediately and stop using it. If you're traveling, the Federal Aviation Administration has issued updated guidance, which builds on its initial request that passengers turn off their Note 7 smartphones and refrain from using them during flights. The FAA's guidance says:

Individuals may only travel by aircraft with a Samsung Galaxy Note 7 smartphone device subject to the CPSC recall if they comply with the following instructions:
·       Turn off the device;
·       Disconnect the device from any charging equipment;
·       Disable all Applications that could inadvertently activate the phone (e.g. alarm clock);
·       Protect the power switch to prevent the phone from being unintentionally activated or turned-on; and
·       Keep the device in carry-on baggage or on their person, and do not place in checked baggage.
