The Samsung Galaxy S5 rumour mill already started to churn while the Galaxy S4 remains one of the top smartphones in the market today. The Galaxy S4, most probably will be replaced by a new device in 2014, which could be the Galaxy S5.

Similar to the Galaxy S3, the Galaxy S4 is expected to remain solid despite being in the market for almost two years. The Galaxy S4 is packed with the marketing power, the revered brand name, the top-of-line hardware and software and the killer specs to do well in a cut-throat competition with the iPhone 5s, Lumia 1020, HTC One and the like.

Rumours suggest that the next smartphone in the Samsung's Galaxy series is expected to come next year. And although the Galaxy S5 remains firmly in the shadows, here is an early look to a match-up between the Galaxy S5 and the Galaxy S4.

Release Date

Since April, the Galaxy S4 is out on shelves already and it is expected to be available even after the release of the Galaxy S5. However, a price tag drop is expected as the Galaxy S5 launch approaches.

As of the moment, there are no official announcements yet about the release date of the Galaxy S5. However, Gottabemobile mentioned on a report that possibly the launch date will be between January and May, while the release date will be between February and June.

Although everything about the Galaxy S5 is inconclusive at this point, rumours suggest that the next Galaxy smartphone will be made of metal, unlike the plastic Galaxy S4.
