Shares of Samsung Electronics Co Ltd fell as much as 1.32 percent in early trade in Seoul following the launch of its new Galaxy S4 smartphone.
The stock under-performed the wider market which was trading roughly flat.
Samsung premiered its latest flagship phone, the Galaxy S4, which sports a bigger display and unconventional features such as gesture controls and which will spearhead its efforts to challenge Apple on its home turf.

- Body size 136.6mm long x 68.9mm wide - slightly smaller than Galaxy S3
- 13 megapixel camera
- Browser scrolling by tilting handset
- Doubles as remote control for smart TV with infrared
The Samsung Galaxy S4 will have a large 13 megapixel camera on its back and a 2 megapixel camera on its front, the company announced today.
Samsung is to broadcast the launch of its new product live on its YouTube channel.
Technology blogs believe the slogan 'Be ready 4 The Next Galaxy' is a hint that the product will be the Galaxy S4.
While Samsung has refused to give anything away in terms of what customers can expect from their mystery offering, experts believe the highly-anticipated S4 handset could seriously disrupt the mobile phone market.
Among its predicted features are a five inch screen, wireless charging capability and a 13-megapixel camera which would be able to take 360 degree pictures.
Some rumours suggest the device - dubbed Samsung's next big challenge to Apple - could include new eye-tracking technology that follows the user's gaze, automatically scrolling through pages as they are read to reveal more text.

If the rumours are to be believed the launch of Samsung's Galaxy S4 has the ability to disrupt the mobile market.
It would be great to see further progress made by Samsung on connecting its devices.
The brand has a huge footprint in our lives - from washing machines and fridges in the kitchen to TVs in the living room, to phones in our pockets. It is already starting to join the dots by using mobile as the connecting device... This is hopefully a stepping point to more connectivity.
Samsung is today expected to unveil its latest Galaxy smartphone at a launch shrouded in secrecy.
The electronics giant is said to be anticipating sales of its new handsets to be as high as 10 million per month.
But it has kept tight-lipped about the design of the mystery product which has been at the centre of much hype in the run-up to its launch.
A teaser picture was published online on Tuesday showing only a shadowed image of the top of a dark handset.
Samsung Mobile US posted the shot on Twitter writing: "The countdown for #TheNextBigThing has begun. Who's ready for the Global Unpacked Event on March 14?"
