Samsung has requested that all of its sales partners stop offering the Galaxy Note 7, following reports of several additional fires over the past few days. It's asking stores and phone carriers worldwide to stop selling and exchanging the replacement units, which were supposedly safe from suddenly bursting into flames.

All Note 7 units currently in consumers hands should be powered down, Samsung says, including replacement units. On its recall page, Samsung says that Note 7 owners "need" to either exchange their phone for another kind of smartphone or obtain a refund.

"It is the right move for Samsung."

"We are working with relevant regulatory bodies to investigate the recently reported cases involving the Galaxy Note 7," Samsung writes in a blog post this evening.

The US Consumer Product Safety Commission commended Samsung for calling for a sales halt. "It is the right move for Samsung to suspend the sale and exchange of all Galaxy Note 7s," chairman Elliot Kaye says. He says the CPSC will "continue our active investigation" into the phone's issues.

This all but ends things for the Note 7. Samsung has now recalled both its original units and its replacement units. Though it's possible Samsung could rework the phone again and roll it back out to consumers, that seems to be an unlikely possibility at this point.

A formal recall through the Consumer Product Safety Commission will almost certainly follow, whenever the commission has finished its investigation. Samsung was criticized the first time around for taking action without waiting for the CPSC, but the commission appears to be fully looped in on and approving of today's actions.
