Our friends over at www.gsmarena.com has good indication that the screen size will increase to 5.5 inches and that the body will be narrower and it looks will be based on the Galaxy S III.
According a trusted source from GSMarena the screen size will be increased to 5.5 inches and will be the Super Amoled kind. Allthough the size increased the body is narrower than its predecessor said the source in a tip which the website recieved.
We hope Samsung will bring it in black and not in the 2 colors of the Galaxy SIII.
What is striking is that the source claimed that the release date has been moved forward to September instead of the rumored October. The reason for that is that Samsung wants to bring it before the Iphone 5, and stealing some users from Apple.
The rumors of an 8MP camera with improved sensor, as well as 1.5 GB of RAM, along with a new Exynos 5250 chipset, featuring a dual-core ARM-15 processor are still unconfirmed at this point.
