The site claims that the Galaxy Note 4 is almost ready for mass production, which is likely to start in July.
From 5 to 10 September, the IFA will be held in Berlin and as in previous years the South Korean company is expected to launch the fourth-generation Note at the event.
Last year, Samsung unveiled the Galaxy Note 3 on September 4 at IFA 2013, but it was not available until three weeks later.
The Samsung Galaxy Note 4 will feature a 7-inch QHD display with a resolution of 1,440 x 2,560 pixels, 3GB RAM and 32GB of storage space, 2.7GHz Qualcomm Snapdragon 805 processor and a 16-megapixel camera.
The device will run on Android 4.4.3 (KitKat) with the TouchWiz interface.
