Samsung Electronics expanded its recall of Galaxy Note 7 smartphones in the United States Thursday to include all replacement devices the company offered following reports of phones overheating and catching fire.
On Tuesday, the South Korean electronics giant confirmed it will no longer manufacture the Galaxy Note 7 due to battery issues.
The battery problems also hit replacement phones issued during a recall last month involving 2.5 million devices.
Samsung said 1.9 million original and replacement Note 7s are recalled in the U.S. The company is giving a $100 credit to Note 7 owners who switch to another Samsung phone.
Shares in Samsung Electronics opened 1% higher on Thursday, rebounding for the first time after three consecutive days of drops.
On Wednesday, Samsung trimmed its profit forecast for the third quarter to $4.6 billion, down from its original guidance of $6.9 billion.
