After the release of iPhone 7, Apple fans are anticipating the unveiling of iPhone 8 to celebrate iPhone's 10th anniversary. But Microsoft's newest smartphone Surface Phone is already making head as the device to challenge the popularity of iPhones.

Despite Apple and Microsoft keeping a tight lid on the information about iPhone 8 and Surface Phone, here are some of the feature rumors that are being talked about in the tech world.

Apple iPhone 8 design might adopt a glass front and back, with stainless steel option

Reliable analyst Ming-Chi Kuo of KGI Securities has told 9 to 5 Mac that the 2017 iPhone will likely adopt a glass front and back design much like iPhone 4 and iPhone 4S. This might be due to reports saying that the Jet Black iPhone7 had been highly popular with customers due to its glossy appeal.

Apple iPhone 8 could possibly have a hyper-advanced camera

According to Apple Insider, a hyper-advanced camera could be real with its discovery of two new Apple patents. These new patents suggest an extremely advanced camera module equipped to capture light in a more effective way.

Microsoft Surface Phone might be a miniature of Surface Tablet

Reports from PC Advisor stated that the Surface Phone might have a 5.5 AMOLED display with a 1440 x 2560 pixel resolution, 4GB worth of RAM and 64GB or 128GB worth of storage with a microSD card slot.

Microsoft Surface Phone to have an impressive camera

It is reported that the Surface Phone is going to have a 64-bit Intel processor and a 21MP rear-facing camera, while the front-facing camera will have 8MP.

Nothing is solid, at this point, but there are enough rumors swirling to compare the two and surmise that the release of these two phones might be the ultimate smartphone showdown.
