The iPhone 5s and iPhone 5c was only released in September and rumors have already swirling on the next generation mobile device. With the display being key to operating the iPhone, most rumors are around the screen size or material used that make up the screen. With rumors abundant on Apple's next generation mobile phone device we have a roundup on what to expected on the rumored iPhone 6, that is expected to be release in 2014:  1. Screen Size To Be Larger: One persistent rumor is that the iPhone screen size will be bigger, although a clear size has not been zeroed in. The latest rumored pointed to a 4.9-inch display after a Chinese site reported, that the Cupertino based company started testing the new device. Increasing the size of the display will also force Apple to increase the density to keep that crisp and visually stunning graphics and continue calling it "Retina Display." Apple struggled to keep up with demand during launch due to scarce resources in the production of the screen. If a larger screen size is to be expected on the iPhone 6, Apple should be sure suppliers can meet demand for a smoother rollout.

2. Sapphire Glass Display: Glass phones can be pretty fragile as one hard drop can make your screen crack and ruin it forever. It was reported that Apple is testing a prototype that has the iPhone display made of sapphire glass, which is currently used on the TouchID home button and lens cover of the iPhone 5s. With the switch in screen material, the mobile device will become more durable and scratch-free. The surface will be able to withstand the daily wear and tear, making it much more resistent. Sapphire is a scarce resource and can be pretty expensive, securing a supplier that can meet the global demand will be Apple's main objective if this is the plan for the next generation device.

3. TouchID Display: The latest rumor has the entire iPhone display function as a trackpad and full-screen TouchID sensor. This allegation makes sense if Apple adopts the sapphire glass display, which is the source that covers the TouchID enabled home button. With a full-screen sensor, Apple designers will find the button obsolete and can extend the screen size to cover the unused area while keeping the footprint of the device the same as previous generations.

4. Camera Improvements: As the iPhone becomes more and more sophisticated, so does the camera. Now-a-days people don't carry an extra camera with them as smartphones have one included in the same device. Apple has been improving the feature and a recently revealed patent shows that further improvements may be on the way. Apple was awarded a patent that allows users to refocus their shots after they have been taken. The system works by capturing light fields, which makes the image editable after the photo is snapped.

5. Facial Detection: Another patent that the tech company was awarded was one that detects faces. This feature will work on mobile devices or computers with the sensor, which will unlock a system by detecting a previously authorized user. The patent also covers environment visuals, such as a background matching the stored information as a passkey to unlock the system. This paired with Apple's recent acquisition of a 3D body sensing company feels like they could combine forces to make this idea a reality. With security being a feature that is constantly requested by users.

6. iOS 8 & A8 Processor: We can surely expect an upgrade to the mobile operating system. With new improvements that will only work with the next generation device. We've seen how the M8 co-processor introduced with the iPhone 5s is a feature that is only seen in this device. The creative minds at Apple are surely hard at work on how to make the system more user friendly and easier to navigate, improving on features that users need on a day-to-day basis.
