Samsung Electronics on Tuesday said it is stopping production of its Galaxy Note 7 smartphones, according to media reports. The Wall Street Journal said production and sales were being discontinued permanently.

Reuters reported that Samsung is considering permanently halting sales of the Note 7.

Samsung temporarily halted production of the smartphone late Sunday to take steps to ensure quality and safety matters because some of the phones are overheating when charged. The firm issued a statement late Monday asking carrier and retail partners globally to stop sales and exchanges of the Galaxy Note7 while the investigation is taking place.

The South Korean company said in a regulatory filing Tuesday that it has made a final decision to stop production for the sake of consumer safety, the Associated Press reported.

Samsung recalled 2.5 million of the original Note 7s last month, with consumers exchanging many of the phones for handsets that Samsung said were safe to use.

Last week, a replacement Note 7 caught fire on a Southwest Airlines flight from Louisville to Baltimore, prompting an evacuation. In the days since, there have been reports of at least two other phones overheating.
