What can fans actually expect with the next generation Samsung Galaxy and iPhone? Let's take a good look at the rumours so far. The iPhone 5S and Galaxy S4 have been barely out of the market, and everyone was already seeing information about successor models from both Apple and Samsung. In anticipation of the next flagship devices hitting the market, it might be a good idea to compare and see if the current flow of rumours are close to reality.

Initial speculations for the Galaxy S5 suggested that the device would be the first Samsung handset to have more premium build materials such as metal and carbon fiber, but subsequent reports prove this is not the case at all. There really is a supplier providing the company with metal, but apparently, it is not for Galaxy S5's bodywork. It doesn't mean that given the Galaxy S5 will not have metal body panels. It could still be plastic. But if the photos leaked are accurate, the device seems to have a similar design to Sony's Xperia Z1. It could also be substantially altered and will get full dust and water proofing.

On the other hand, the iPhone 6 is rumoured to have a bigger 4.8- or 5-inch HD display panel with a super thin bezel to ensure the 6 mm thick chassis does not get too substantial.

The iPhone is pretty much guaranteed to have the same 16, 32 and 64 GB storage options. But some think the iPhone 6 might just have a 128 GB option like the new iPads.

Meanwhile, the Galaxy S5 might have 32 and 64 GB models, and it's safer to assume it will also have a 16 GB variant. Samsung has a microSD capability, though.

The iPhone 6 might have a quantum dot display, while the Galaxy S5 might have an RGB AMOLED with WQHD resolution one. New rumours suggest that Samsung might switch to LTPS LCD and OLED, though.

Not a lot has been said about iPhone's camera, but if Apple's iPhone 5S is still set on the "less is more" approach, it could then be set for an 8 MP iSight BSI (back-illuminated sensor) with a few smart tweaks to pre- and post-image processing and a true tone dual LED white or amber flash. It could either be the same with the iPhone 6 or there could be a drastic change with a 13 MP camera in place.

Apple has also filed a new patent, suggesting that the new imaging tech inside the iPhone 6 could feature Lytro-like capabilities. Lytro is a kind of camera that allows the user to capture a photo and dynamically select a focal point later on. This is achieved through plenoptic technology. Apple's tweaking of the iPhone 5S software and enhancement of its sensor were received with critical acclaim, and while the iPhone 6 could bump up its camera technology, the real action really takes place with the software and sensor.
