Samsung had to recall and discontinue its Galaxy Note 7 smartphone due to battery issues that caused some phones to overheat and catch fire. Multiple reported incidents of burning and exploding phones led Samsung to officially ask carriers to stop sales of the Note 7 and encourage users to power down their phones and receive refunds or replacements. The recall is estimated to cost Samsung $1 billion and damaged its brand and market share. Samsung is facing bans on the phone from airlines and other transportation services due to safety concerns over the exploding batteries.
