The Korean electronics giant posted an image to the social networking site Twitter, showing a front view of the Android smartphone, although it is mostly obscured by a shadowy foreground.
“It is a dark image, and hence it becomes difficult to fathom much from it. The images shows the front panel with “Samsung” written at the top of it. But the design of the phone in the image is reminiscent of the Galaxy S III. However, it could be a piece of misinformation to lead the curious technology buffs astray,” writes IBN Live.
As written in the tweet, the Korean tech giant has been promoting the Galaxy S 4 with its “Unpacked” marketing campaign, publishing online a poster and video that teases the smartphone.
Earlier on Monday, a series of images published on a Chinese forum for the Samsung fans demonstrated a smartphone that is reported to be the new Galaxy S4.
The handset appears a bit larger than the previous version and The Verge, which picked up the photos, reports that the forum claims the phone has a 1080p display, runs Android 4.2.1, has a 1.8GHz Universal5410 processor and 2GB of RAM.
According to The Verge, those specs remind of recent rumours about the specifications of the Samsung Galaxy S4. The Universal5410, says The Verge, is “likely a codename for the Exynos Octa 5410, an eight-core processor with four A15 cores for power and four A7 cores for power efficiency”.
Earlier in the day SamMobile reported that the Galaxy S4 would feature a “floating touch” display, which would allow a user to control the highly anticipated device without touching the screen. Hovering a finger over a photo album might bring up a preview of the pictures inside, for example.
This follows reports last week claiming that the expected smartphone would scroll the screen by monitoring the movement of the user’s eyes.
The Samsung S Pen, used with the Galaxy Note range, includes an Air View feature which activates certain functions just by holding the stylus close to the screen without touching it.
The website cites its insiders claiming that the new version of the famous smartphone will also have a PHOLED screen, more energy efficient than a standard OLED screen.
The Galaxy S4is also expected to feature a 13-megapixel camera and a new photography mode called Samsung Orb that will capture 360-degree images.
Screenshots published online last week suggested that the upcoming device would feature a 5-inch, 1080×1920 pixel display with 480 pixel-per-inch density.
Rumors from DigiTimes suggest that the S4 will feature wireless charging using the Qi standard supported by Google and Nokia, rather than the A4WP standard which Samsung has backed until now, The Telegraph writes.
Whatever the specifics, there is likely to be keen interest around the launch event, which takes place at midnight (UK time) on Thursday.
It will be the first US launch of Samsung’s flagship Galaxy phone in three years, as Samsung looks to step up competition in the crucial US mobile phone market.
