Are the days numbered for the Samsung Galaxy Note 7?

Samsung seemed to have the issue under control but consumers started to report that the new Note 7, which replaced the recalled hazardous Note 7, also began to catch fire.

Last week, authorities had to evacuate a Southwest Airlines flight when a replacement phone began emitting smoke.  

AT&T Inc, the No.2 U.S. wireless carrier, said on Sunday that it will stop exchanging new Note 7 smartphones due to reports of fires from replacement devices that Samsung has said used safe batteries.

No.3 wireless carrier T-Mobile US Inc said it was also temporarily halting sales of new Note 7s as well as exchanges while Samsung investigated 'multiple reports of issues' with its flagship device.

T-Mobile offered customers who brought in their Note 7s a $25 credit on their phone bill.

Samsung announced on September 2 a global recall of 2.5 million Note 7s in 10 markets including the United States due to faulty batteries causing some of the phones to catch fire. 

Samsung earlier said it was investigating reports of 'heat damage issues' and would share its findings when the investigation is complete.

'If we determine a product safety issue exists, Samsung will take immediate steps approved by the CPSC (U.S. Consumer Product Safety Commission) to resolve the situation,' Samsung told said in a statement.
