 MWC 2026 officially gets underway on March 2 and will continue through March 5, but the announcements are already coming ahead of its start. We can always count on the annual tech event to bring tons of new phones, laptops and tablets, and we're expecting to see some robots and other gadgets too — plus plenty of AI news, of course. In addition to the announcements, MWC is our chance to get hands-on time with some of the most interesting new devices, like the Xiaomi 17 Ultra.
We'll be updating this story as the week goes on to keep you in the loop on everything that caught our attention, so keep checking back here for the latest MWC news.
Xiaomi x LeicaXiaomi kicked off MWC this year by announcing the global launch of its 17 Ultra smartphone, which debuted first in China back in December. It's unclear if the phone will ever come to the US, but it's now rolling out in Europe. Xiaomi teamed up again with Leica to make a photography-focused smartphone, and the 17 Ultra sports a 1-inch 50-megapixel camera sensor with a f/1.67 lens, a telephoto setup with a 200MP 1/1.4-inch sensor, and a 50MP ultrawide camera. There's also a manual zoom ring around the camera.

 China's biggest phone makers continue to relentlessly forge ahead with high-spec phones that you may never see in the US. With the Xiaomi 17 Ultra this year, the company has continued its pattern from previous iterations by focusing on powerful camera sensors, huge batteries and… being selective about global availability.
Xiaomi's 17 series is launching across multiple European territories months after its Asia debut, but at the time of writing, no word yet on US availability. Another logistical point of interest? When we last checked out Xiaomi's devices, it was the 15 series, and the company has decided to skip 16 and leap straight to 17, conveniently matching Apple's latest number.
Storied camera brand Leica has been involved with Xiaomi's phones for a few years and its newest flagship doesn't disappoint in that regard, because this is another Xiaomi device dedicated to photography.

The 17 Ultra has a huge 1-inch 50-megapixel main camera sensor with a f/1.67 lens, and a telephoto setup with a 200MP 1/1.4-inch sensor and going up to 4.3x optical zoom. Xiaomi claims it's capable of up to 17x "optical-level zoom," but quality doesn't measure up to, say, the Oppo Find X9, with its dedicated telescopic lens add-on. There's also a 50MP ultrawide camera to round things out.

 Tecno just unveiled a rather intriguing modular smartphone concept design at MWC 2026. The standout feature here is likely the size. Most modular smartphone concepts start bulky and only get bulkier once attaching accessories. Tecno's base smartphone is just 4.9mm thin, which is significantly thinner than a pencil and the iPhone Air.
Of course, the size increases with each attached module. However, snapping on the power bank module makes the thickness comparable to a standard modern smartphone. Another key feature here is how these various modular components stick together. Tecno has developed new interconnection technology that uses both magnets and pin connectors. This should make it easy to both attach and remove components.
The company says this phone has been designed to grow with the user through hardware expansion. To that end, Tecno has developed 10 modules. There are various camera lenses and something that looks like a dedicated gaming controller.

While the magnets are for attaching, the pin connectors assist with power delivery. Data transmission between the phone and the modules is handled wirelessly, with the ability to switch between Wi-Fi, Bluetooth and mmWave depending on
