Cast your mind back a decade or so, and smartphone makers were obsessed with shrinking the bezel on phones. Screens got bigger, the black bars around them got smaller, and for a while it looked like truly edge-to-edge displays were imminent.
Then, progress just stopped. The bezel shrunk down until it was a millimeter or so on every side, on just about every phone, and phone manufacturers seemed to agree as one that this was probably far enough.
Tecno, a budget brand in the same family as Itel and Infinix, has stepped up to see if it could push things just a little further. Its new device, the Bezelless, is strictly a concept phone, never destined to go on sale, but it proves the point: It is possible to remove a smartphone screen’s bezel entirely — so long as you don’t mind still having a little frame around the edge.
The screen runs from edge to edge, with no visible inactive area. At the right angle you can see the tiniest black line in the corners, but that’s about it. The frame, however, is a bit thicker than on some other phones. It’s still a decent OLED display, with a 144Hz refresh rate and 1.5K resolution.
The company sent me a prototype of the Bezelless ahead of its unveiling at the IFA trade show in Berlin, so I could see it in action for myself. There is truly no black border at all around the 144Hz, 1.5K, 6.78-inch screen, except for the tiniest hint of a fraction of a black line I can see just under the frame when I look at the phone at an angle. Looking head-on, the screen ends, then the frame begins, and that’s that.
There is still an inactive edge to the OLED panel, but Tecno has hidden it beneath the frame. The key to the design is the use of two layers of cover glass: The top layer goes up to the edge of the frame, while the lower glass layer and the OLED panel itself both extend underneath it. Designing the phone this way had knock-on effects. It meant building the phone backwards, mounting the display from the phone’s rear rather than its front, which in turn requires securing the screen from the front, with a custom adhesive that sits between the frame and the lower piece of glass.

And while I might cynically point out that the frame here is probably a hair thicker than on most other modern smartphones, it’s a fractional thing. Stand the Bezelless side by side with this year’s flagship Samsung Galaxy S26 Plus, and there’s clearly a little less material wrapping around the screen — though there’s not much in it.
Tecno bullishly claims that the Bezelless “redefines how users will interact with their phones in the AI era,” which feels a bit much. Manufacturers stopped shrinking the bezel because it got small enough that most people stopped caring. Removing a strip of black from the screen doesn’t make this phone feel dramatically more impressive or useful than any other I’ve tested this year. A functional upgrade, this is not.
