Its new design enables the device to fold in half horizontally.
Samsung on Wednesday unveiled a new foldable smartphone that folds into a square, racing ahead in folding devices after it launched its first model in September this year.
The South Korean tech giant teased the new concept today at the Samsung Developer Conference 2019 in the United States, reports NDTV.
Showing the mock-up on a screen, Head of Framework R&D Group at Samsung's mobile communications Sally Hyesoon Jeong said, "The amazing thing with the foldable technology is that it can also become more compact like this."
World's largest smartphone maker is powering ahead with the launch of 5G phones and $2,000 foldable handsets as it battles rivals Apple and Huawei Technologies in an increasingly saturated market.
Its new design enables the device to fold in half horizontally. "This brand new form factor we are now exploring not only easily fits in your pocket but it also changes the way you use the phone," Jeong said.
China's Huawei started taking orders last week in China for its eagerly awaited foldable smartphone, hoping to make up for weak overseas sales amid US trade sanctions.
Samsung did not provide details about when the square-folding phone would be launched.
"While we can't comment on future products, Samsung is committed to pioneering the foldable category, including investing in the development of new form factors," Samsung official said.
