Samsung Galaxy S5 to launch in mid-March at a London event: Report

There's no doubt that the Samsung Galaxy S5 has become one of the most eagerly-anticipated smartphones of the year, as leaks related to the device just keep coming in.A new rumour now claims that the South Korean handset maker will be holding a global event in London scheduled around mid-March. Further, the event is said to be for the unveiling of the company's next flagship smartphone, widely expected to be dubbed Galaxy S5. The news comes via a freelance journalist named Flavio, who claims to get the information from a reliable source. The tweet reads, "Samsung to hold its next Global launch (S5?) event in London in a mid March date, a reliable source confirmed me."
It's worth pointing out that, while speaking about the launch date of the alleged Galaxy S5 recently, Samsung's mobile executive VP, Lee Young-hee, hinted that the flagship smartphone (Galaxy S5) might be launched around March and April.
The Samsung VP further added that the company has been considering the inclusion of an iris-scanning feature on the Samsung Galaxy S5. In addition, the VP also revealed plans about company's successor to the Galaxy Gear. The eye-scanning/iris-recognition feature has not been introduced on any smartphone (from a major manufacturer) as an unlocking method, and if Samsung actually uses this, it would become the first handset maker to debut the feature on a smartphone.
It's worth mentioning that Samsung has been said to release two versions of the alleged Galaxy S5: a premium variant which will sport a metal chassis and a flexible OLED, and a variant which will come with the usual plastic body, as found on other Galaxy smartphones. An earlier report emerging from Korea had claimed that Samsung is adopting a blend of stainless steel (to increase the endurance) and plastic (to check the weight) to build the alleged 'premium' variant of the Samsung Galaxy S5.
Rumoured specifications of the alleged Galaxy S5 include a 64-bit Exynos chipset or a new Snapdragon chipset, 3GB of RAM, a 16-megapixel rear camera, a 4000mAh battery and Android 4.4 KitKat with TouchWiz UI on top.
