Phone Arena reports via Korean site eNuri that the Galaxy S IV is the first smartphone in the series to feature the stylus as the Korean manufacturer seeks to "unite its Note series with the flagship Galaxy S IV", allegedly confirmed by a quote from a Samsung official.
According to latest rumours from SamMobile, the Samsung Galaxy S IV is being developed under the codename 'Project J' and is likely to be launched in April next year.
Reports have indicated that the Galaxy S IV will indeed come with a 4.99-inch Super AMOLED display with 1920x1080 resolution, giving it a pixel density of 441ppi. That report is in line with other rumours which suggested that Samsung and LG are working on smartphones with full-HD display, which may be released in first-half of 2013.
Additionally, murmurs are that the new Samsung Android flagship will run on Jelly Bean and feature a 2 GHz quad-core Exynos processor and an 8-core GPU. It is also rumoured that the smartphone will use ARM big.LITTLE architecture featuring a combination of an energy-efficient A7 processor and an A15 one for simple and heavy task processing.
There's more buzz about the device being equipped with a 13-megapixel camera rear auto-focus camera and slightly thicker, 9.2mm body.
Other rumours suggest that the device will come with an unbreakable screen that could be a great attraction for the smartphone in terms of sales. Samsung, however, has not officially made any statement in this regard.
