Tecno’s Bezel-less Concept Smartphone Has Zero Millimeters of Bezel That Sounds Perfect Until You Touch It

Years of smartphone presentations treated screen-to-body ratio like a scoreboard. Smaller black borders meant progress. Xiaomi chased the idea with the Mi Mix series. Samsung briefly tried waterfall curves that bent the glass over the sides. One extreme concept even wrapped the display around the back so the number could climb past 100 percent. Those experiments eventually settled down. Curved edges brought reflections, weaker durability, and accidental touches. Premium phones today sit at roughly one to two millimeters of border all the way around. Some people still call those borders unacceptable. Most of them were never going to buy the phone in the first place.

Earlier this summer, Marques Brownlee (MKBHD) received an email from Tecno, a company that claimed to have a concept that would finish the job. This new phone has a premium design and a 6.7-inch screen that extends all the way to the edges. When held straight on, the black border that typically surrounds most current screens vanishes. From corner to corner, edge to edge, the glass meets the silver frame with no space in between. When compared to a Pixel 11 Pro, the contrast is obvious. The Pixel still has a little black strip between the active pixels and the metal, which is highly obvious. This Tecno gadget knocks it out totally.

Their approach for removing that strip is internal stacking, in which the screen remains flat but the metal frame protrudes just beyond the glass, allowing the black edge of the screen to be hidden underneath. From typical viewing angles, it’s obvious. Tilt the phone or picture lifting the frame off and you’ll notice a sliver of unused glass peeking out, and that raised lip becomes really crucial when you’re actually holding the thing.

Every time you swipe from the top to check your notifications or from the bottom to return home, your finger scrapes against a metal edge. It disrupts the fluid flow, which is far more upsetting than a little traditional bezel would be. It’s a shame because the phone itself still seems very striking when you look at it. Put it to use, and a modest border with rounded edges begins to sound appealing. One big issue with the concept is the number of cases. Any case that wraps around the sides will only cover part of the screen.

The rest of the design, however, is rather competent, with a brilliant screen that refreshes at 144Hz, a triple camera array on the back, and a 6000mAh battery inside. It’s so light that it nearly feels like one of those dummy devices used to showcase phones in store windows. The hole-punch selfie camera is in its customary location. Fair play to anyone who wants to chase that full-screen ideal; many people would prefer to hide the camera behind glass, but the rest of the gear does not feel like a toy.

The major surprise lies on the back, which Tecno hardly highlighted in the press materials, but it’s far more interesting than the front. There’s a holographic lenticular pattern going on, which gives this three-dimensional butterfly-wing appearance that appears to be lifting right off the surface. MKBHD struggled to get a good photo of it, but he believes it’s one of the best examples of that optical trick currently accessible. If this design were to make it onto store shelves, it would require a clear case to be bundled with the smartphone.
