With 2014 drawing to a close, speculations are rife about the next-gen smartphones from two leading tech firms of the world, Apple and Samsung. While Samsung is all set to release its upcoming flagship smartphone Galaxy S6 sometime next year, tech enthusiasts are hopeful that Apple will also launch its next iPhone, purportedly the iPhone 7, in 2015.

Recently, Christian Today has come out with a comparison of the specs of these two purported smartphones to find which device will be successful in being the buyers' favorite.

According to reports circulating on the Internet, the iPhone 7, which may even be dubbed as iPhone 6s, is likely to sport a sapphire glass display, which was expected to be incorporated in the iPhone 6 and iPhone 6 Plus that were launched last September.

In addition, it is expected that the display screen of the upcoming iPhone will support 3D viewing. Rumors are also there that the iPhone 7 will come with a new A9 processor.

Some reports have claimed that the next iPhone will come with an amazing 21-megapixel camera, in order to compete with smartphones of other manufacturers. The device may possibly also sport a two-lens system enabling the users to shoot sharp images which will be comparable to the snaps taken with DSLR cameras. However, this may be possible only if Apple collaborates with Sony.

On the other hand, the release of the Samsung Galaxy S6 is quite certain, while Apple's next iPhone is merely speculation. According to rumors, the upcoming Samsung flagship smartphone may have a 2560 x 1440 resolution quad HD display.

For the American market, the device is likely to pack a 64-bit processor that will be comparable to the Qualcomm Snapdragon 810. In addition, the phone may also sport a microSD slot enabling users to upgrade the device's memory up to 256 GB.

A number of reports have claimed that the Galaxy S6 will come with a 20-megapixel OIS-enabled primary camera having 4K video recording capacity. On the other hand, its selfie shooter will be 5 megapixels.

While Apple has yet to make any announcement whatsoever regarding its upcoming flagship smartphone, tech enthusiasts as well as experts are expecting that the South Korean tech titan will announce the release of Galaxy S6 at the Mobile World Congress in Barcelona sometime next year.
