The Galaxy Note 7, Samsung’s newest smartphone is being recalled again, this time for good. Units were reported catching fire due to a battery cell defect on both the original Galaxy Note 7’s and their replacements.
It appears that the replacements are catching fire due to a second battery flaw that is different from the one causing the original recall. Preliminary examination shows an issue with batteries supplied by China’s Amperex Technology even though they were considered to be the safe alternative to Samsung SDI’s faulty batteries.
The issue is believed to have spread into the supply line once Samsung started replacing the Galaxy Note 7 that had batteries sourced from Samsung SDI. A US consumer safety agency cited in the report claims the batteries from Samsung’s own affiliate were slightly too large for the device. Since they were a bit too large for the compartment, installing them would crimp the corner which would cause the batteries to short circuit and overheat.
Samsung has yet to release an official explanation.
