BELLEVUE, Wash., Dec. 28 (UPI) -- T-Mobile has become the first cellphone carrier to send out an update to the recalled Samsung Galaxy Note 7 handsets that will effectively make the device useless by preventing it from being charged.
The phones also will display an on-screen message about the recall, according to a posting by T-Mobile on Tuesday.
AT&T and Sprint users will receive the updates on Jan. 5 but Verizon hasn't agreed to the update.
Battery problems have plagued the device, and after two global recalls, Samsung announced on Oct. 11 production was ceased. A total 2.5 million devices were sold, including 1 million in the United States, where it went on the market on Aug. 19.
Samsung revealed that it expects to lose $3.1 billion over two quarters because the Galaxy Note 7 was taken off the market.
The carriers agreed on the killer update after some Note 7 owners continued to use their devices despite the recall amid incidents of batteries exploding, smoking or catching fire. About 7 percent devices sold in the United States were still being used two weeks ago, Samsung said.
Customers are urged to immediately power down and and bring it back to a carrier's store for a full refund and a replacement device.
Samsung is offering a $100 bill credit to customers who exchange the device for another Samsung smartphone.
The Department of Transportation banned all of the recalled devices form airplanes on Oct. 15.
