Sources from S. Korea claim that the Samsung Galaxy Note 4 will be launched next month in two versions, a regular one with a flat screen and a "Galaxy Note Edge" vversion with a curved display. Rumor says that Samsung applied to trademark the brand name Galaxy Note Edge at the United States Patent and Trademark Office on August 5, but the application papers Samsung Electronics filed didn?t mention any other details besides the name.

The Galaxy Note 4 is expected to come with a 5.7 inch Quad HD display and either a new version of the Qualcomm Snapdragon 805 or an Exynos processor. In addition, the device will come with an ultraviolet sensor together with heartbeat measurement and fingerprint recognition.

Samsung has already released the Galaxy Alpha, an intermediate level smartphone in which Samsung Electronics used metal in the side of the case for the first time in the Samsung smartphone line.

The Galaxy Alpha will be released in 150 countries worldwide starting from early September.
