The much-anticipated release, which follows successful sales of the S3, is expected to ramp up Samsung’s competition with Apple’s iPhone.
The S4 is predicted to run on the Android operating system, while HumanIPO reported last week it will feature innovative new software which will follow a user’s eyes to make reading and browsing easier.
Samsung has pre-empted the launch with a large advertising campaign, which involve a series of videos of a small boy charged with guarding a “top secret” box.
HumanIPO will report full details of the Samsung Galaxy S4 launch tomorrow.
