According to latest reports Electronics giant Samsung’s investigation into its Galaxy Note 7 chaos has established that the overheating and even phones catching fires was triggered by faulty batteries.

Back in October 2016 Samsung announced to discontinue its iPhone rival after an earlier failed recall and re-release.

The South Korean firm reportedly revealed that it was smart phones batteries issue instead of its software and hardware.

Reports said that the recall have cost $5.3 billion and was enormously destructive for Samsung standing.

Plenty of investigations have “concluded that batteries were found to be the cause of the Note 7 incidents”, the South Korean technology giant said in a statement.

Meanwhile Samsung said that errors both in design and engineering affected batteries by two different makers.

Tests have showed that the snags centre on the large batteries not fitting well into the phones, as well as not enough insulation material within the batteries.

Samsung said it was “taking responsibility for our failure to ultimately identify and verify the issues arising out of the battery design and manufacturing process”.

Samsung’s Note 7 device was launched in August 2016 and promoted as a large-screen top-end device and was made to compete with Apple’s iPhone.

However in September 2016, Samsung had to recall about 2.5 million phones after objections of overheating and burning batteries.

The company asserted that all swapped devices were safe. However, that was followed by reports that those phones were also catching fire.

Furthermore the tech giant affirmed that there would be no repeat of the fires in future devices such as the upcoming S8.

“We look forward to moving ahead with a renewed commitment to safety. The lessons of the past several months are now deeply reflected in our processes and in our culture.”
