Samsung Electronics Co. plans to begin selling a trifold smartphone later this year, joining rival Huawei Technologies Co. in exploring a relatively untested market.

Samsung's new Galaxy Z Fold 7, Z Flip 7, and Z Flip 7 FE have sharper cameras, more powerful multitasking software, and expanded AI capabilities, all housed in luxurious, well-built bodies.

Samsung Electronics Co. introduced three new foldable smartphones in an effort to cement its grip on the category and broaden mainstream appeal before Apple Inc. debuts its first version next year.

Samsung's Galaxy Z Fold 7 is arguably the biggest upgrade to its foldable phone lineup in years.
