Samsung Electronics is permanently stopping production of its Galaxy Note 7 smartphones amid problems that are causing the devices to burst into flames, reports said.

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, according to the Associated Press. The Wall Street Journal also said production and sales were being discontinued. Samsung has not commented publicly.

Late Monday, Samsung had asked its global network of retailers to stop selling the Note 7 while it investigated the matter. And on Sunday, the world’s largest smartphone maker temporarily halted production because some of the phones are overheating when charged.
