"Samsung will hold an event in Berlin to announce the Note 4 on Sep 3," a company executive was quoted as saying.

The South Korean company hopes that the Note 4 will help it get a fresh momentum to lift its handset business at a time when the company is being threatened by the rise of Chinese budget handset manufacturers.

Galaxy Note 4 features Qualcomm processors with support for fourth-generation LTE mobile wireless technology.  The device will come with a 5.7-inch display. Other rumoured specifications include the addition of a Snapdragon 805 chipset for the Chinese, Korean, Japanese and North American markets, while all other regions including Europe would receive a variant with an Exynos SoC.
