Samsung Galaxy S5 release date may happen in March 2014 marking the first birthday of its predecessor - the Galaxy S4.

Five months before the alleged launch of Galaxy S5, rumours are already swirling on the possible features that the South Korean tech company will include in its upcoming handset.

Samsung was criticized before for its lack of innovation in upgrading the physical components used on the body of their devices and by constantly using plastic casings, which are viewed as cheap compared to the materials used by its rivals.

However, whispers say that the upcoming Samsung Galaxy S5 release date will pack high-end and amazing features that will beat all other smartphones in the market.

Below are the five killer features that you might see at the rumoured Samsung Galaxy S5 release date in March next year.

64-bit chip processor - The rumoured Samsung Galaxy S5 may pack the faster 64-bit processor. Although this already comes in the new iPhone 5S, Samsung may follow suit to offer its fans a faster chipset in their future smartphones.

Android 4.4 KitKat OS - Android 4.4 KitKat is expected to make its debut this October. Thus, future Android devices will definitely get the chocolate-flavored Android OS, including the Samsung Galaxy S5.

20.7 MP camera - Samsung is commended on easily increasing the megapixels of their camera. Samsung Galaxy S3 featured an 8 megapixels cam and the Galaxy S4 packed a 13 megapixels rear shooter. This time, whispers say that the Galaxy S5 will come with 20.7MP rear camera.

4K video - The most exciting rumour so far is that the new Samsung Galaxy S5 will come with 4K video resolution that is beyond Full HD.

IGZO screen display - Rumours claimed that S4's successor will utilize Sharp's new screen technology that was initially rumoured to arrive in new iPhones.
