Samsung Electronics Co. will release its Galaxy S5 smartphone by April and is considering using iris scanning technology for the first time as it readies the new high-end handset to compete with Apple Inc.’s latest iPhones.

The S5 will be paired with a new wearable device that will be an evolution of the Galaxy Gear smartwatch, Lee Young Hee, executive vice president of the company’s mobile business, said in a Jan. 6 interview. Samsung, which posted profit this week that missed analyst estimates, will debut the new products together as it also boosts marketing of tablet computers.

“We’ve been announcing our first flagship model in the first half of each year, around March and April, and we are still targeting for release around that time,” Lee said. “When we release our S5 device, you can also expect a Gear successor with more advanced functions, and the bulky design will also be improved.”

Samsung, which sells one of every three smartphones globally, is adding new features and models to fend off Apple in the high-end market and Chinese makers luring budget customers with handsets for $100. Asia’s biggest technology company will announce at least one other wearable device this year, Lee said without elaborating.

Samsung registered a design in South Korea in October for eyeglasses that can show information from a smartphone and enable users to take calls.
