Samsung has made it clear that anyone with a Galaxy Note 7 needs to power it down and return it because that particular phone has a nasty tendency to burst into flames.

But it looks as though a lot of people are still using a Samsung Galaxy Note 7, according to data published in the last week by Apteligent, which tracks Android device usage.

In fact, usage on Thursday was equal to usage on September 2, when the Galaxy Note 7 was recalled, according to the data.

The number of people still using a phone that's banned on flights underscores how big and complicated Samsung's recall is.

"Samsung, together with carriers, is working to communicate the US Department of Transportation's new order to ban all Galaxy Note 7 devices in carry-on and checked baggage on flights," a Samsung spokesperson told Business Insider on Friday. "We have encouraged airlines to issue similar communications directly to their passengers. Any Galaxy Note 7 owner should visit their carrier and retail store to participate in the US Note 7 refund and exchange program now. We realize this is an inconvenience, but your safety has to remain our top priority."

After Samsung said it had found the problem that caused the phones to catch on fire, it started giving customers replacement Galaxy Note 7s. But then those started to catch on fire, too.

Since then, Samsung has told every Galaxy Note 7 user to return theirs, offering discounts, alternatives, and even a fireproof return box to help speed up the process.

It probably doesn't help the process that some package carriers have said they will not handle shipments of the Samsung Galaxy Note 7.
