Samsung is now most famous mobile phone name in the whole world.They are now challenging Apple phones.so now they are going to release their next smart phone.it's Samsung Galaxy S4.

SAMSUNG GALAXY S4 RELEASE DATE

Invites have now been sent out to a launch event for the Samsung Galaxy S4. The launch will take place in New York on the 14th of March. The event is officially titled Samsung unpacked 2013 Episode 1 - and invites us to 'Come and meet the next Galaxy'.

The Samsung S3 launch took place in London on the 3rd of May 2012, so Samsung has only allowed for 10 months between handsets. The S3 then went on sale to the public on the 29th of May worldwide, and so you can expect to have the S4 in your hands by the middle of April at the latest.
As expected, leaks surrounding the S4's suspected price have been thin on the ground, although we can expect it to cost as much as the S3 when it launched back in May - a wallet-busting $755. Once again though the tough competition from Google's own Nexus 4 device may force Samsung to lower its price in order to compete - unless of course the hardware specification is a big step forward.

On contract you're likely to be looking at $45-60 a month minimum, and considerably more with a 4G service such as EE. This will be an expensive handset, though probably still a little less than the iPhone 5 costs.
