At a time when the tech world is busy churning rumors about the next version of Samsung’s flagship smartphone, unofficially dubbed the Galaxy S4, a new report Tuesday spiced up the whole story even further, claiming that the South Korean tech giant is busy with efforts to introduce a new high-end smartphone with model numbers of the device already confirmed.

Sammobile reported that it had received the first model numbers of Samsung’s new high-end device – the Samsung GT-I9500 and GT-I9505 (probably, a LTE version). The device will run on either Android or TIZEN, an open source, standards-based software platform.

“We know that Samsung’s first TIZEN developer device is using GT-I9500 as its model number which could mean TIZEN is close to come, or, other possibility is that Samsung changed the model number of the next-generation Galaxy S device,” the report added.

Given that number four is believed to be unlucky in Korea, the report suggested that the GT-I9500 could be the Galaxy S4 smartphone. The existing Galaxy S3’s model number is I9300 and Samsung could skip I9400 in favor of I9500 and I9505 (with the latter being the LTE version), for the next version of its flagship device, Android Authority has reported.

The Sammobile report also said that Samsung has never used the number four as a product code for its high-end devices. In addition, the company is also reportedly testing software for both the handset versions - GT-I9500 and GT-I9505.

As for rumors about the phone’s features go, the Samsung Galaxy S4 is likely to be powered by Exynos 5450 chipset with a quad-core Cortex-A15 processor. The device is also rumored to have a 13-megapixel camera.

In terms of the phone’s display, some reports suggest that it could feature a flexible, unbreakable display, a new display technology that the company has been experimenting with for quite some time now.

Many reports also suggest recently that Samsung was preparing a 4.99-inch Full HD Super AMOLED screen (441 ppi) to be showcased at the annual Consumer Electronics Convention (CES) in January 2013, a display that is likely to be featured in Samsung Galaxy S4.

When it comes to the smartphone’s release time frame, speculations were rife that it could be unveiled in early 2013 with two major events, the Consumer Electronics Show (CES) and the Mobile World Congress (MWC), being scheduled during that time.

However, the company officially confirmed that it won’t reveal its next Galaxy smartphone at the CES in January, but would focus more on its television products along with other electronics during the event.

Another report from Sammobile earlier this month stated citing “fresh rumors from Korea,” that Samsung had named its next Galaxy smartphone as “Project J” and that it could release the device in April, next year.

When Samsung’s 2013 sales figures for handsets are concerned, a company executive told The Korea Times that it would ship 510 million handsets next year, of which 390 million would be smartphones.

However, these figures contrast an earlier outlook of Samsung’s 2013 handset sales by market research firm Gartner, which predicted that the company is likely to sell between 250-300 million smartphones next year.
