TCL’s zigzag concertina-style folding smartphone has one screen and two hinges


TCL, the company best known in the mobile world for holding the license to make BlackBerry devices, has made no secret of its foldable phone plans. It has shown off, and talked about, folding smartphones and the hinges that are so essential to their operation since the beginning of the year. Now it has revealed a spectacular new type of folding device design, and it’s unlike any we’ve seen before.

Take a look at the photo. The TCL phone, which is strictly a concept and does not have a name or release date, has a dual hinge that unfolds the massive 10-inch screen, concertina-style. Like the Huawei Mate X, the TCL device has a single screen, but here there are two hinges splitting it into thirds. Open, it has a single, 10-inch expanse of a display, while folding it down once lessens the screen real-estate, and for a second time gives you a thick, single-screen viewing experience. That’s a lot of versatility, and plenty of potential for media viewing and productivity use.

The TCL phone shown to CNET was not a working version, therefore should be treated as a concept of what’s possible, rather than an example of what TCL will release in the future. The brand announced its first phone — the TCL Plex — to wear the TCL name in September, and in an interview with Digital Trends at the time, said it would be ready to talk about foldable phones during Mobile World Congress 2020, which will take place at the end of February. However, more details about its screen technology will likely come at CES 2020 at the beginning of the year. We may not have long to wait before we see if this is representative of what TCL will launch over the coming year.

TCL’s zigzag concertina folding smartphone is very unusual, and another in the growing number of experimental folding phone designs we’re seeing. TCL has also shown off other folding phone designs that use a single hinge for either vertical or horizontal use, while it’s almost certain Motorola will introduce a vertically folding smartphone at an event on November 13. Xiaomi has teased an intriguing folding phone design in the past too, and Microsoft turned everything on its head with the dual-screen Surface Duo. The Galaxy Fold and Huawei Mate X are only the beginning.

Your $1,000 smartphone is a bad deal. These cheap phones prove it

Samsung is once again here to entice you with its latest crop of foldable phones. The temptation they pose is easy to give into. You might think, what could go wrong with an almighty, well-stocked $1,000 phone?

Worth noticing, however, is the fact that plenty of other smartphones offer a much higher value for your money and can potentially fill your $1,000 purchase with remorse. That's not my intention, especially if you have already preordered the Samsung Galaxy Z Fold 5 or Galaxy Z Flip 5. But if you are looking for potential alternatives that save you lots of money while bringing you features comparable to phones that cost almost $1,000, here we have some examples.

Google has finally entered the foldable market with the Google Pixel Fold. It provides a great stock Android experience, direct from Google, that’s powered by the impressive Tensor G2 chip with 12GB of RAM and your choice of 256GB or 512GB storage. One of the best things about any Google Pixel device is the camera. It’s hard to take a bad photo with a Google Pixel, and that includes the Pixel Fold.

The one major competitor for Google’s Pixel Fold right now, at least in the U.S., is the Samsung Galaxy Z Fold 4. Samsung’s foldable packs in Snapdragon 8+ Gen 1 chip with 12GB RAM and up to 1TB storage. And that's all joined by some mighty impressive camera hardware.

I’ve reviewed phones for 10 years — this is my favorite one of 2023

I've been reviewing smartphones for a long time — over 10 years, to be exact. I've reviewed many of the best phones of all time, some mediocre ones, and a few duds that I'd rather forget about. It can be difficult to keep track of all the phones I've tested and evaluated in the past decade, but there are a few that truly stand out. The Motorola Razr Plus is one such smartphone.

The Motorola Razr Plus has been my go-to smartphone for a few weeks now, and it's one of those rare phones I can't stop thinking about. Is it perfect? Not at all. The cameras should be much better, especially given how expensive it is. The battery doesn't last any longer than a day. Wireless charging is slow, and there's no reverse wireless charging. Motorola's track record for software updates leaves a lot to be desired.
