Samsung Electronics will roll out a software update for its Galaxy Note 7 customers in South Korea as part of efforts to address overheating concerns.

The software update will limit the battery’s capacity of the smartphone at 60% to prevent overheating.

Earlier this month, Samsung issued a voluntary recall for its Galaxy Note7 devices after finding 35 cases of the device overheating or catching fire.

A week later, it asked Galaxy Note7 users in South Korea to immediately switch off their phones and exchange them as soon as possible.

Samsung Electronics Mobile Communications Business president DJ Koh said: “We are expediting replacement devices so that they can be provided through the exchange program as conveniently as possible and in compliance with related regulations.”

However, it is not clear whether Samsung will release software update to fix the overheating issue in other countries, including the US, the publication reported.

The company said the software’s availability in other markets may depend on the local situation and requirements.

Samsung said in a statement:  “We plan to carry out the Galaxy Note 7 software update starting from 2 a.m. on 20 September.

“This is a measure we are taking for our customers’ safety but we apologise for the inconvenience caused.”

Earlier this week, US authorities warned airline passengers not to turn on or charge their Samsung Galaxy Note 7 phones when on board a plane, following reports of devices catching fire.

The Federal Aviation Administration (FAA) also advised passengers also not to stow them in any checked baggage.

In August, Samsung unveiled the Galaxy Note 7, which updates its flagship phablet line with new durability and security features.

The smartphone features a new iris scanner to boost the security of the device. The company developed its own proprietary algorithm to assign a digital signature to each user’s iris.
