    Are tri-foldable phones the next big thing? I tried one from an upstart brand

    Prakhar Khanna/ZDNETI’ve been rooting for tri-fold phones since I used the Huawei Mate XT Ultimate. I found that device to be more useful than a book-style foldable. Now, here comes the Tecno Phantom Ultimate 2, which is a similar tri-fold foldable. However, unlike the Huawei phone, the Tecno Phantom Ultimate 2 isn’t available to buy. The phone was launched as a concept in August 2024 and Tecno is showcasing a working prototype at Mobile World Congress. While the phone is expected to be launched in the future, I got limited hands-on time with the tri-fold at the event — and was impressed. Also: I tested Huawei’s $3,600 tri-foldable, and it made me question why tablets still existThe Tecno Phantom Ultimate 2 is 11mm thick, slimmer than the Huawei Mate XT’s 12.8mm-thick design. When folded to single-screen mode, Tecno’s device is closer to the Galaxy Z Fold 6 form factor than the Oppo Find N5 or Huawei’s tri-fold design. The Tecno tri-fold concept can go from a folded 6.48-inch outer screen size to a 10-inch display. The device has an LTPO OLED screen with a 1,620 x 2,880 pixel resolution. The hinges felt quite strong and held the screen where I wanted it to be. Tecno expects the device to last for up to 300,000 folds. The company also says it developed a battery as thin as 0.25mm to fit inside the device.  More

    Samsung teased me with its Galaxy S25 Edge at MWC – and I was ready to give up my Ultra

    Kerry Wan/ZDNETThere it was: the unreleased Samsung Galaxy S25 Edge hanging on wires at the Mobile World Congress (MWC) show floor. Going into the morning of the Barcelona trade show, I knew I had to make a beeline to the Samsung booth to avoid yet another crowded photo-op with the upcoming Galaxy phone. So I got my badge, skipped to Hall 3, whipped out the DSLR, and started shooting.Also: Best of MWC 2025: The 7 most impressive products you shouldn’t missWith a phone as thin as the S25 Edge — it’s rumored to measure around 6mm — there’s one golden shot that every photographer tries to capture. It requires a steady hand, a bit of waiting for passersby to leave the frame, and just the right amount of focus on that sliver of side railing. The result? The essence of Samsung’s most innovative hardware update to the S line in years, pictured above.I’ll admit: even without holding the S25 Edge, I was ready to give up everything then and there. My Xiaomi 15 Ultra, suited in its photography kit, was already dragging down one side of my jacket. A lighter, thinner, more burdenless-to-carry phone wouldn’t have hurt. More

    Huawei’s D2 smartwatch monitors your blood pressure – Apple, take note

    ZDNETThere are several blood pressure monitors on the market, but few reliable smartwatches with that functionality. Chinese tech brand Huawei’s Watch D2 could change that.Huawei’s Watch D2 includes an ambulatory blood pressure monitoring device, the first wrist-based device of its kind. The wearable is certified by China’s National Medical Products Association and the EU’s Medical Device Regulation. According to Huawei, the device is one-fifth the width and 1/25th the volume of a traditional electronic blood pressure monitor, designed with portability and continuity in mind. The smartwatch is not for sale in the US.Also: The best blood pressure watches of 2025: Expert testedThe smartwatch can measure blood pressure at pre-set intervals for 24 hours to calculate averages and BP rhythms, supplemented by its TruSense System for improved speed and accuracy. This sort of blood pressure monitoring occurring over a day can help those with hypertension and cardiovascular issues get a clearer picture of their blood pressure for longer than a typical doctor’s visit. Several smartwatches have blood pressure monitor capabilities but require extra equipment. For example, Samsung’s Galaxy Watch 7 can track your blood pressure with the help of the Samsung Health Monitor app; however, to use the feature, you need to calibrate it with a cuff-based blood pressure monitor. Samsung’s wearable also hasn’t received FDA approval as a BPM, so it can’t be used for diagnosis or treatment. The Apple Watch can aggregate your blood pressure data in its device but can’t take measurements itself.  More
