Samsung can’t put the second half of the year behind it fast enough. And its troubles are yet to subside; quite the contrary, they are worsening.

Two major U.S. carriers — AT&T and T-Mobile — on Sunday said they would halt all sales and exchanges of the troubled Samsung phone following reports of fires caused by new and “safe” Note 7 units.

“Based on recent reports, we’re no longer exchanging new Note 7s at this time, pending further investigation of these reported incidents,” AT&T said in an email sent to The Verge Sunday. “We still encourage customers with a recalled Note 7 to visit an AT&T location to exchange that device for another Samsung smartphone or other smartphone of their choice.”

T-Mobile head John Legere on Twitter said his company would stop selling and exchanging the Note 7 “out of an abundance of caution for our customers.” The carrier encourages subscribers to exchange their Note 7s with another device on T-Mobile and is giving a $25 credit on their bill.

U.S regulators are currently investigating the replacement Note 7 handset that caught fire on a Southwest Airlines flight on October 5. The plane was evacuated prior to take-off and no injuries were reported. At least four other incidents of replacement Note 7s catching fire have been reported in the U.S. alone.

In Minnesota, a young girl said she experienced a “weird, burning sensation” while holding her device; the phone later showed burn marks that were consistent with previous cases of Note 7s that were literally too hot to handle.

A man from Kentucky told local news outlet WKYT he woke up to find his bedroom filled with black smoke from his burnt Note 7. The man went on to say Samsung knew about it and didn’t say anything.

Even more damning, a Samsung representative allegedly sent him an inadvertent text message (likely intended for another company official) which said: “Just now got this. I can try and slow him down if we think it will matter, or we just let him do what he keeps threatening to do and see if he does it.”

The fourth incident involves a man in Virginia whose replacement Note 7 “burst into flames” on his nightstand on October 9th. The man provided The Verge with copies of his receipts and photographs of his Note 7 box to corroborate his story.

The latest reported incident came from a Texas family who witnessed their device catch fire on a table. It had been replaced at a retail store in September.

Samsung has since issued a statement in which it said it is investigating the fires and working with U.S. authorities — in particular, the Consumer Product Safety Commission (CPSC) — throughout the investigation. The company promises to share its findings “as soon as possible.” You can read the full statement below.

Samsung understands the concern our carriers and consumers must be feeling after recent reports have raised questions about our newly released replacement Note 7 devices.

We continue to move quickly to investigate the reported case to determine the cause and will share findings as soon as possible.

We remain in close contact with the CPSC throughout this process.

If we conclude a safety issue exists, we will work with the CPSC to take immediate steps to address the situation.

We want to reassure our customers that we take every report seriously and we appreciate their patience as we work diligently through this process.

At this point, it seems almost certain that we’ll hear about another global recall soon, and that the once-promising flagship will be pulled from shelves for good this time.

If the reports are indeed accurate, Samsung should cut its losses and discontinue the Note 7, and focus its efforts on making amends with affected customers. And it has to knock everyone’s socks off with next year’s S8 to even have a chance at winning back public opinion. That phone ought to be capable of doing more than just scanning irises and taking pictures with two rear cameras.

UPDATE, October 10: Verizon also announced today it would stop issuing replacement Note 7 phones to its customers. The company has the most wireless subscribers in the U.S.

UPDATE 2, October 11: The Galaxy Note 7 is done for. Samsung has asked all carriers and retail partners to “stop sales and exchanges” of the phone. Here’s the latest statement from the company.

We are working with relevant regulatory bodies to investigate the recently reported cases involving the Galaxy Note 7. Because consumers’ safety remains our top priority, Samsung will ask all carrier and retail partners globally to stop sales and exchanges of the Galaxy Note 7 while the investigation is taking place.

We remain committed to working diligently with appropriate regulatory authorities to take all necessary steps to resolve the situation. Consumers with either an original Galaxy Note 7 or replacement Galaxy Note 7 device should power down and stop using the device and take advantage of the remedies available.

UPDATE 3, October 12: Samsung said on Tuesday it would permanently cease production and sales of the Galaxy Note 7, The Wall Street Journal reports. To quote the company’s statement:

Taking our customer’s safety as our highest priority, we have decided to halt sales and production of the Galaxy Note 7.

The move effectively ends the phablet’s brief and embattled existence. Analysts said it could cost the company $17 billion in losses and forgone sales.
