Some customers have reported that the device's battery has exploded during charging, which presents a huge safety issue to Galaxy Note 7 owners. Fortunately, Samsung has issued a recall on over two million Galaxy Note 7 units that may be affected. But going forward, they will have to regain the trust of consumers, who may be weary of buying Samsung devices in the future due to safety concerns. To address the issue directly, Samsung will no longer use batteries made by Samsung SDI in the Galaxy Note 7.
