Android Geeks have also been able to confirm other details about the device. The site reports that an engineer working for Samsung  has confirmed that it will have a camera feature the company is calling the Samsung Orb, which is expected to work similarly to the Photo Sphere function that was part of the Android 4.2 Jelly Bean update.

That feature first came out on the Nexus 4, which was also the first smartphone to have the Jelly Bean operating system already on it. The Galaxy S4 is also expected to become one of the first smartphones to feature a panorama mode that captures images in 360 degrees. It is also expected to have a 13-megapixel camera.

Currently, there are two different rumors about what type of processor Samsung Galaxy S4 will feature. Some say it will use Qualcomm’s Snapdragon 600 quad core processor, while others say it will have Samsung Electronics Co., Ltd. (LON:BC94) (KRX:005930)’s own Exynos 5 Octa processor with an octo-core processor. Either way, the phone will undoubtedly be a major upgrade, both for Galaxy S3 users and even for iPhone 5 users.

Mobile World Live reports that the Galaxy S4 is also expected to have a full 1080p HD display that’s a full 5 inches, plus some new software innovations, like the ability to answer the phone simply by putting it to the ear rather than having to hit a button. In addition, it is expected to feature eye monitoring, which enables the device to know when the user is actually looking at it so that it doesn’t shut the screen off while the user is actively looking at it.

The site also reports that a mini version of the device is expected out in May.
