We finally know what caused some 35 Note 7s to go up in flames over the past three weeks.
In a Q&A article spotted by BGR on the Samsung UK website, the Korean company says, “Based on our investigation, we learned that there was an issue with the battery cell. An overheating of the battery cell occurred when the anode-to-cathode came into contact which is a very rare manufacturing process error.”
It’s not the most detailed explanation, but the good news here is that there’s nothing wrong with the device itself. Moreover, those who own one of the company’s other phones have nothing to worry about. “This is only limited to the Galaxy Note7. Each model has a different design and manufacturing process,” says Samsung in the same article.
Prior to the recall, approximately 70 percent of the more than 2.5-million Note 7s out in the wild had a battery from Samsung SDI, the culprit behind the 35 exploding phones. Moving forward, Samsung has temporarily stopped sourcing Note 7 batteries from its subsidiary.
Bloomberg estimates the recall will cost Samsung more than $1-billion when all is said and done. Samsung has not commented on whether the estimate is accurate, but an executive from the company has said the number is “heartbreaking.”
