In a video posted online, Xiaomi teases a working prototype of a phone with a double-folding display and a more symmetrical design than Samsung's foldable phone
China's Xiaomi has become the latest smartphone maker to tease a folding smartphone, dropping the below video clip of its president …
Context & Ripple Effects
Xiaomi's prototype video lands mid-race: Samsung had already teased its foldable that opens into a tablet in late 2018 with mass production promised within months, and weeks later a leaked banner at MWC showed Huawei's outward-folding Mate X. By claiming a double-folding, more symmetrical design, Xiaomi is positioning itself not as a fast follower but as setting the form-factor agenda.
The tease proved durable rather than vaporware: Xiaomi eventually shipped its first foldable, the Mi Mix Fold, in March 2021, and has since iterated through the Mix Fold 4 and its first flip foldable, while Samsung was separately reported to be working on its own double-folding device.
First-order effects
- Samsung enters its foldable launch window facing a rival whose demo implies a more advanced hinge architecture, raising the bar for what counts as a credible first-generation product.
- Huawei's Mate X reveal at MWC now competes for attention against two claimed designs instead of one, splitting the 'innovation' narrative among three vendors.
Second-order effects
- Display and hinge suppliers gain leverage as multiple vendors chase distinct folding geometries — inward, outward, and double-folding — turning panel capability into a differentiator rather than a commodity input.
- Samsung's reported follow-on work on a clamshell and an outward-folding device suggests competitive pressure to broaden beyond a single book-style form factor rather than defend one design.
Third-order effects
- If the pattern holds, foldables settle into a portfolio market — book-style, flip, and multi-fold devices coexisting per vendor — as later coverage of Xiaomi shipping both a Fold and a Flip line already indicates.
- Chinese vendors using design leadership to challenge Korean incumbents on hardware form factors becomes a repeatable playbook, shifting premium-segment competition from specs to mechanical engineering.
The trend: Foldable smartphones are moving from single-hinge concept teases toward a multi-form-factor market where Chinese and Korean vendors race each other on hinge and display engineering.
