Subsequent reports about Note 7 battery explosions prompted Samsung to issue a global recall of all the almost 2.5 million units sold by the company within a couple of weeks of the handset's launch.
Airlines have banned customers from using the smartphones on flights, and the evacuation of a Southwest Airlines Co plane earlier this week was blamed on smoke caused by a replacement device.
Following reports of what was supposed to be a "safe" Note 7 exploding on Southwest Airlines, AndroidPolice is reporting that all four major United States carriers (Verizon, AT&T, T-Mobile, and Sprint) have now elected to exchange safe Note 7s for any other phones they have in stock. A previous Tech Times report highlighted that AT&T is thinking of stopping all sales of Galaxy Note 7.
While Samsung has replaced more than one million Galaxy Note 7 devices with versions that are said to have batteries that are "not vulnerable to overheating and catching fire", at least one report suggests the replacement devices are also prone to problems. The incident has raised safety concerns of Galaxy Note 7 replacement units. "This applies to recalled, replacement and newly purchased Note7s", says T-Mobile. "Verizon online customers may also exchange their replacement Note 7 smartphones at Verizon stores beginning Saturday, October 8".
According to rumors, Samsung rushed the Galaxy Note 7 into production in an effort to outshine Apple after hearing that the iPhone 7 would not feature major design changes. The stock has recovered since losing US$22 billion of market value after the recall was announced on Sept 1 and hasn't significantly underperformed its Nasdaq technology peers in that period. Samsung and the U.S. CPSC are still investigating the Southwest Airlines incident, and Samsung still hasn't gone on the record confirming that it was indeed a replacement device. The Verge has reached out both to Samsung and AT&T for comment.
