Samsung will unveil a thinner version of its flagship foldable smartphone at a launch likely set to take place next month, as it battles Chinese rivals to deliver the slimmest devices to the market.

Folding phones, which have a single screen that can fold in half, came in focus when Samsung first launched such a device in 2019. But Chinese players, in particular Honor and Oppo, have since aggressively released foldables that are thinner and lighter than Samsung’s offerings.

Why are slim foldables important?

“With foldables, thinness has become more critical than ever because people aren’t prepared to accept the compromise for a thicker and heavier phone to get the real estate that a folding phone can deliver,” Ben Wood, chief analyst at CCS Insight, told CNBC on Thursday.

Honor, Oppo and other Chinese players have used their slim designs to differentiate themselves from Samsung.
