CheckMag | From color-changing to eye-tracking tech: Top 4 jaw-dropping phones from MWC 2024

Infinix has certainly captured the spotlight at MWC 2024 with its innovative color-changing phone, a concept first introduced at CES 2024. Utilizing the advanced E-Ink Prism technology, this prototype, named the Infinix E, boasts a unique ability to alter color particles in the phone's casing through varying voltage levels. This method achieves its visual transformations without draining the device's battery life.

The Infinix E stands out with its innovative, customizable color panel on the back. This feature breaks the mold of traditionally static smartphone designs, offering a range of four vibrant, interchangeable designs. Each design incorporates 60 customizable areas, enabling users to modify their phone's appearance based on time, mood, or personal preference.

Despite the excitement it has generated, the Infinix E is not yet available for purchase. As reported by Engadget, Infinix is still addressing certain technical challenges, particularly those related to thermal performance and the device's overall thickness. 

TCL is making a significant stride in smartphone display technology with its introduction of the NxtPaper technology in the new TCL 50 XE NxtPaper 5G and TCL 50 XL NxtPaper 5G smartphones. A standout feature of these devices is their emphasis on eye comfort. The NxtPaper displays, measuring 6.6 inches on the XE and 6.78 inches on the XL, are designed to mimic the look and feel of paper. This innovative technology significantly reduces up to 61% of harmful blue light and eliminates screen glare, offering a more comfortable and natural viewing experience similar to reading on paper.

The TCL 50 XE NxtPaper 5G, with its MediaTek 6835 23E+ chipset, 4GB of expandable RAM, and a 5,010mAh battery with 33W fast charging, is priced at $199. The device also features a dual-camera setup with a 50MP main and 5MP ultrawide lens, plus a 32MP front-facing camera.

For those seeking enhanced features, the TCL 50 XL NxtPaper 5G comes with a slightly better MediaTek 23E+ chip, a base 6GB RAM (expandable up to 2TB), and the same 5,010mAh battery, albeit with 18W fast charging. Its camera system includes a 50MP main, 5MP ultrawide, and a 2MP depth sensor, along with an 8MP selfie camera, priced at $229.

At MWC 2024, Tecno has unveiled its Phantom Ultimate prototype, featuring a cutting-edge rollable display. The device starts with a 6.55-inch screen that extends to 7.11 inches at the push of a button, transforming it into a larger, tablet-sized display within 1.3 seconds.

The Phantom Ultimate incorporates a "second display" on the back, which is essentially the main screen that wraps around, visible through a transparent section. This design eliminates the need for a separate rear screen, allowing for efficient double-sided display usage, showing time and notifications when retracted. The device measures 9.93mm in thickness, maintaining a sleek profile despite its advanced features.

As a concept phone, the general release of the Tecno Phantom Ultimate remains uncertain. Concerns were raised about the durability of the flexible glass and the longevity of the motorized mechanism, particularly in terms of how many cycles the phone can withstand before experiencing wear and tear.

Honor has announced the global launch of its Magic 6 Pro at MWC 2024, following its initial debut in China. The flagship smartphone stands out with its array of AI-powered features. A notable highlight is the "Magic Capsule," Honor's version of a Dynamic Island-style interface, which uses AI to track the user's eyes and automatically opens apps when notifications are viewed. Another AI feature, the "Magic Portal," intelligently identifies events or addresses in messages, offering direct links to maps or calendar apps. Further enhancing its AI capabilities, Honor is developing a tool that creates videos from photos using text prompts, processed on-device through its MagicLM technology. 

Beyond its AI functionalities, the Magic 6 Pro aligns with typical flagship specifications. It's equipped with the Snapdragon 8 Gen 3 processor and boasts a substantial 5,600mAh battery, supporting up to 80W fast charging and 66W wireless charging.

The device is equipped with industry-leading drop-resistant glass, challenging the durability of the Gorilla Glass Armor featured in the Samsung Galaxy S24 Ultra (available on Amazon). It has a 6.8-inch 120Hz OLED display with a 2800 x 1280 resolution and a peak brightness of 5,000 nits. Camera-wise, the Magic 6 Pro includes a 50-megapixel main camera with a variable aperture (f/1.4 to f/2.0), a 50-megapixel ultrawide, and a 180-megapixel periscope lens with 2.5x optical zoom.
