STORY: Samsung Electronics unveiled its latest foldable smartphones on Wednesday.

It's bolstering AI functions in a bid to challenge Apple's dominance in the premium market.

With a starting price of around $1,900, the Galaxy Z Fold 6 is Samsung's lightest and slimmest phone yet.

Meanwhile, the clamshell Galaxy Z Flip 6 starts at $1,100.

The world's largest smartphone maker pioneered the foldable segment in 2019.

The launch is crucial as competitors are surging into the market.

Samsung's foldable phone shipment share fell from 81% in 2022 to 63% in 2023.

That's according to data provider Canalys.

The Flip boasts a longer battery life, a higher resolution camera, and a new vapor chamber to keep the phone cooler.

The hope is to reduce pain points discovered through customer interviews.

Samsung is also offering new AI functions including a "listening mode" that provides simultaneous interpretation by voice when paired with Galaxy Buds earphones.

It also worked with Alphabet's Google for new AI search functions.

On the accessories side, Samsung is making a bet on more sophisticated health monitoring functions.

Its offerings include the Galaxy Ring.

At just under $400, it is light -- about three grams or less.

It can be worn in the shower or while swimming, and can constantly monitor heart rate and stress levels as well as help control a Samsung phone's camera or alarm.

A slew of new health functions were added to its Galaxy Watch products, too.

It's now a U.S. FDA-approved monitoring device for sleep apnea.

The products will be available starting on July 24 in South Korea, North America and Europe.
