While foldables represent the next evolution of smartphones, the current crop isn’t exactly how we imagined these devices to be. When the likes of Samsung first teased the idea of phones that transform into tablets, that dream didn’t involve squarish tablets or thick and narrow phones. The ideal is a normal-looking phone that almost magically becomes a regular tablet when it unfolds, something that wasn’t easily feasible given the technology of the past two to three years. We might be on the cusp of the next stage of the foldable revolution, and TECNO is only too happy to show off not only a tri-fold device but one that is only 11.1mm thick when folded into a conventional phone.

Designer: TECNO

A phone with two hinges that fold in opposite directions is one of the ways we can get the best of both worlds, but it’s easier said than done, naturally. Not only do you have to consider the durability of the display panel that will bend at opposite angles in two areas, the thickness of the folded “phone” also becomes a conundrum. If bi-fold phones like the Samsung Galaxy Fold are already considered to be thick, imagine how much worse three layers would be.

That’s the boast that TECNO is making with the Phantom Ultimate 2 concept, a tri-fold device that is only 11.1mm thick when folded. That’s just around 2mm thicker than the average regular foldable, which is still thick but not by much. TECNO doesn’t give the exact dimensions for the unfolded tablet, but it’s bound to be really thin in that case.

This design gives us a regular 6.48-inch candybar phone that turns into a regular 10-inch tablet and vice-versa, delivering the best of both worlds in a single device. And if that weren’t enough, TECNO shows that the device also supports stylus input, making it an all-in-one entertainment and business computer in your pocket. There are various modes made possible by this novel folding design, though some might be a bit more questionable than others, like putting the sensitive foldable screen in contact with a table.

The TECNO Phantom Ultimate 2 concept will be shown off at IFA 2024 in Berlin next week, though its existence hardly means it’s something we’ll be able to buy soon. Samsung has also shown off tri-fold prototypes, both of the “Z” and “G” varieties, yet none have come to market yet. Then again, the forerunner of foldable devices seems to be content taking a more conservative approach, so it wouldn’t come as a surprise if TECNO or even Huawei would land this novelty on shelves first.
