Nearly a year after Samsung recalled and discontinued its Galaxy Note 7 smartphones after the devices were found to overheat and explode, another phone in the company’s lineup is under recall: 10,000 Galaxy Note 4 devices have been recalled amid concerns they could overheat, posing a risk of fire or burns to users. 

The recall involves about 10,200 batteries placed in refurbished AT&T Samsung Galaxy Note 4 cellphones by FedEx Supply Chain and distributed as replacement phones through AT&T’s Insurance program only from Dec. 2016 to April 2017.
