Samsung has released a teaser video for its upcoming Galaxy S IV Android phone.

The company published the video onto its YouTube account overnight under the title "Be ready 4 the next Galaxy".

The video shows a boy taking delivery of a secret package presumably containing the Galaxy S IV. However, it reveals no new information about the hotly anticipated handset.

The Galaxy S IV hasn't officially been announced yet but will be unveiled on Thursday 14 March at a press event in New York.

The device is one of the most anticipated Android phones of 2013 and is the successor to Samsung's popular Galaxy S III smartphone.

The Galaxy S IV is widely expected to feature a 1.8GHz Exynos 5 Octa 5410 processor, a 4.99in Super AMOLED full HD display, and a 13-megapixel camera.

Last week, US blog Sammobile published a rumour suggesting the Galaxy S IV will be sold in six different variants.

Samsung announced in January that it had sold more than 100 million smartphones in the Galaxy series since the original Galaxy S launch in May 2010.
