Samsung may be the world's top mobile phone maker, but it does not mean it does not encounter sales problems like what's happening with its Galaxy S4. 

In a report by BGR, its sales have reportedly gone down by 13 percent since April, the month it was released. As a result, they are planning to host an event specifically to raise sales. 

According to Reuters, a whopping two-thirds of Samsung's entire profit comes from the mobile phone sales. 

The report also said the Korean manufacturer will invite over 400 investors and analysts just to restore their confidence in the company. 

Other things that will likely make its ways to the agenda include the newly announced Galaxy Note 3, and the Galaxy Gear smartwatch. 

This is the first time Samsung will hold this kind of event since Sang-Hoon Lee took over president chores. 

The event is reported to be held on November 6th.
