Samsung Electronics ran an apology ad in major U.S. newspapers on Monday, pledging to thoroughly look into what led to the massive recall of its Galaxy Note 7 smartphone and renewing its commitment to consumer safety.

"An important tenet of our mission is to offer best-in-class safety and quality. Recently, we fell short on this promise. For this we are truly sorry," Samsung said in the ad that appeared in the Washington Post, the New York Times and the Wall Street Journal in the name of Gregory Lee, president and CEO of Samsung Electronics North America.

"We will re-examine every aspect of the device, including all hardware, software, manufacturing and the overall battery structure. We will move as quickly as possible, but will take the time needed to get the right answers," Samsung said.

The ad also mentioned the company's recent decision to voluntarily recall some 2.8 million washing machines due to a potential safety problem, saying the company is working hard to address the problem and offer customers remedy options.

"Most importantly, safety remains our top priority. We will listen to you, learn from this and act in a way that allows us to earn back your trust," the company said. "We are grateful for your ongoing support and again, we are truly sorry." (Yonhap)
