In a packed press conference at its offices in southern Seoul Monday, the world's biggest smartphone maker again apologized to customers around the world for the bungling of its product release. Phones were initially recalled and replaced, but the replacement devices also began to catch fire.
Presentations at the announcement by outside investigators backed up Samsung's findings, which indicate batteries from supplier A were shorting because of a design flaw or in some cases a lack of insulation tape. And batteries from supplier B — which were issued in the replacement phones following the initial recall — were catching fire because of a separate manufacturing defect.
