Back in September, Samsung's Galaxy Note 7 was on everyone's beware list, including airports, when the phones suddenly began exploding.

Now, the company is offering an explanation.

According to Samsung's latest report, two different battery malfunctions were the blame.

Watch this Business Insider video for a full explanation:

When preparing the first batch of Note 7s, the batteries inserted were too large, causing the phones to overheat and explode.

In a rush to release the second shipment after recalling the first one, the company used a battery from a different supplier. But this battery also had a defect, resulting in the same issue as before.

Samsung then decided to ditch the product altogether and start anew.

Now the company has revamped its testing process, developing a new eight-point battery check to ensure all phones are safe to use.

The testing includes an X-ray and visual inspection as well as an accelerated usage and charge and discharge examination.

The tech company has even enlisted the help of battery advisers made up of professors from the University of Cambridge, the University of California at Berkeley and Stanford University.

With the updated research in place, will you invest in Samsung’s next phone? The Galaxy S8 is scheduled to hit the market this spring.
