Samsung Galaxy Note 7 fiasco has revealed that the company is testing batteries for all of its phones in-house for sales in the US. A report in the Wall Street Journal, points out this practice is different from what other smartphone OEMs follow in the US. Samsung has ended production for the Galaxy Note 7 as it was overheating, and catching fire in some cases. The company has even started messaging consumers who bought the phone to return the device.
According to the WSJ report, all other OEMs have their batteries tested at third-party labs certified by CITA, which is the US wireless industry’s trade group. This is a must for any smartphone company trying to sell a device with a US carrier, where most phones are still carrier locked. However, according to WSJ, Samsung is the only one on the list of major manufacturers which was relying on its own lab for the certification.
But it seems even Samsung’s lab failed to detect any problem with the device, both the original Note 7 and the replacement phones. An earlier report from New York Times has said Samsung own engineers were unable to diagnose the problem even in September when the first recall was issued.
The report from NYT said since the problem couldn’t be recreated it was assumed (incorrectly) that the fault lay with the batteries from one factory. However, the problems with the replacement phones showed this wasn’t true, and even the new devices kept overheating.
Samsung has said it will make changes to its “quality-assurance processes” after the Galaxy Note 7 disaster. Improved testing aside, Samsung’s Galaxy Note 7 brand has taken a significant hit after this disaster, given the faulty battery slipped past twice from the company.
With the Galaxy Note 7 production ending, the South-Korean firm stands to face a total of $5.3 billion loss in the third quarter. The Note 7 is now a device which has been banned by all major airlines across the world due to the fire risk. Samsung is yet to comment or confirm on what exactly is causing the Note 7 battery to overheat, and it remains to be seen when it will have a convincing answer.
