Reuters claims that Samsung will announce the results of its investigation on January 23, one day before it reveals its fourth-quarter earnings. Additionally, Samsung will announce new measures it is implementing in an effort to prevent a similar issue from occurring again.

According to today’s report, Samsung was able to replicate the fires in its testing, but that the cause of the fires could not be explained by software-related problems or hardware design.

Investors and analysts say it is critical for Samsung to provide a detailed, convincing explanation on what went wrong with the Note 7 phones and how it will prevent such problems from recurring.

The source told Reuters that Samsung was able to replicate the fires during its investigation and that the cause for the fires could not be explained by hardware design or software-related matters.

Samsung’s Galaxy Note 7 was recalled due to issues related to the device randomly catching fire. Reports have claimed that Samsung is out as much as $1 billion for the recall. The revelation that the battery is to blame for the issue isn’t necessarily a new one, but it’s notable that the issue was not due to software issues.
