Although the post was removed almost immediately, a lot of the Samsung Galaxy S4 reports as of late are centered on a Samsung Lebanon Facebook reply where representatives told a customer that the upcoming flagship phone will be out in May 2013.
This, for some, sounds like a more plausible release date for the Galaxy S4 compared to most of the other speculations and rumors going around. Most sources are expecting the Galaxy S4 out in the market by April, while there are a select few, including market analysts, who believe March 2013 could be a very likely release schedule as it comes right after the rumored Mobile World Congress announcement. Samsung, like many other companies, typically uses a 12-month product life cycle for the Galaxy S series, so if the Galaxy S4 will drop by May 2013, this would give the current Galaxy S3 flagship a “lifespan”, so to say, of exactly one year.
Regarding the expected internals of the Galaxy S4, the expectation is that it would be powered by a new quad-core Exynos 5450 processor crafted with Cortex-A15 architecture. Although the quad-core Exynos 4412 underneath the Galaxy S3 is still a pretty good processor (unfortunately one American Galaxy S3 owners cannot experience underneath their devices), most believe that CPUs manufactured with Cortex-A15 architecture should take over soon, being faster and more energy efficient than other processors. With all that in mind, the Exynos 5450 just might overtake the Qualcomm Snapdragon S4 Pro as the most popular system-on-chip used on smartphones.
Other than the clearly interesting potential for a state-of-the-art processor on the Galaxy S4, the next-generation device might also feature a screen measuring 5 inches diagonally, with the soon-to-be-ubiquitous display resolution of 1920 x 1080. It could also be 4.99 inches, allowing Samsung to have a slightly higher pixels-per-inch density than other phones whose screens measure exactly 5 inches. Aside from that, the Galaxy S4 might include a 13-megapixel rear camera, 2 GB or 3 GB RAM and a larger battery, perhaps one greater than 3,000 mAh.
