New rumors emerged claiming that the successor of Samsung Galaxy S3 will arrive on mid-2013 after the announcement of the upcoming Google's Android OS - Key Lime Pie.

Some Samsung Galaxy S3 users are already complaining on the slow rolling out Android Jelly Bean updates since launch, chances are Samsung will not be looking for a repeat debacle and will almost certainly therefore launch the S4 with Key Lime Pie right out of the box.

Samsung did not anticipated the release of LG Nexus 4, which quickly gained popularity and high demand as it is packed with the latest version of Jelly Bean OS.

Neither Samsung nor Google has yet given any mention to the progress or the existence of Android Key Lime Pie, with release date rumors spanning anywhere from April to October.

In either case, the new build of Android will almost certainly debut with a new Nexus Smartphone before being made available for use with other devices, which could see the wait for the Galaxy S4 launch stretch even further.

Another rumor claimed that Samsung Galaxy S4 will sport a flexible OLED 1080p HD displays. This technology will likely also be featured with the Samsung Galaxy Note 3. This contradicts the previous report that the device will be equipped with an indestructible screen display.

It was previously reported that the Samsung Galaxy S4 will sport a 5-inch full HD display with full 1080p and a whopping 440 pixels per inch. The device will be powered by two quad core chips.

The Galaxy S4 might also sport a 13-megapixel rear-facing camera, which will intimate other smartphones with 8MP back shooters.

The handset should come with a minimum of 2GB RAM, although there are reports that Samsung is testing an unidentified smartphone with 3GB RAM.

Samsung also began mass producing 128GB memory chips for smartphones and tablets earlier this year, and we could see storage capacities that high as early as next year. With this, the Samsung will continue its reign in producing devices with large storage capacity.

Samsung kept mum on the rumors surrounding the upcoming Samsung Galaxy S4. There is no official comment from the South Korea's tech giant.
