According to the media in South Korea, Samsung's decision to fast-track the new model is based on slowing sales of the Galaxy S4, which nonetheless got off to a strong start last spring. The company sold 10 million Galaxy S4 phones worldwide within one month of the smartphone's release.
In addition, rumors suggesting that the forthcoming Galaxy S5 will be equipped with a 64-bit processor could point to another reason for Samsung's sense of urgency. The brand likely fears losing ground to Apple, whose iPhone 5s, launched in September 2013, features the same processor. The Galaxy S5 is also rumored to have a 16MP camera.
