South Korean electronic giants Samsung and LG are in a patent row over the technology that enables users to control their smartphones with their eyes, setting the ground for a legal battle ahead of the launch of their flagship handsets in April.

Samsung's Galaxy S4 is due to be launched in April.

According to a report Tuesday by Yonhap, an LG Electronics plans to review potential patent infringements when the Samsung Galaxy S4 hits the market.

The Galaxy S4 will feature what the company calls "smart pause" while LG calls a similar eye-tracking technology it has in its upcoming Optimus G Pro, "smart video". Both pauses a video when a user looks away, and resumes it when the user turns back to the device.

The eye-tracking technology has been touted as one of the key features of the Galaxy S4, but LG claims it already applied for the technology patent in August 2009, according to Yonhap.
A Samsung official told the newspaper a patent infringement was not possible as both technologies used different methods.
