Alcatel’s new phones include the A5 LED (with a back covered in LED lights)

Chinese device maker TCL’s most anticipated phone of Mobile World Congress is probably the BlackBerry KeyOne, which was unveiled Saturday. But TCL also makes and sells phones under the Alcatel brand, and the company has three new models on display at the show.

Two are budget devices that don’t really stand out all that much. But the third really does catch your eye… with bright flashing lights.

It’s called the Alcatel A5 LED and it’s a 5.2 inch smartphone that has an array of LED lights covering its back panel.

The Alcatel A5 LED lets you use the Color Catcher 2.0 app to design your own flashing color combinations to go with music playback or other experiences. You can also switch between patterns by shaking the phone.

Aside from the LED lights, the phone has pretty mundane specs, including a 5.2 inch, 1280 x 720 pixel IPS display, a 1.5 GHz MediaTek MT6753 octa-core processor, 2GB of RAM, 16GB of storage, an 8MP rear camera,5MP front camera, 2,800 mAh battery, and Android 6.0 software.

Update: The Verge notes that the LED rear panel is removable, and Alcatel is showing off other panels including a speaker case and battery extender that can attach to the back of the Alcatel A5. So it might be a Moto Z-like modular platform… but right now Alcatel is making no promises to offer any modules other than the LED light panel.

The company’s other new phones include

• Alcatel A3 – a 5.2 inch phone with a 720p display, a MediaTek MT6737 quad-core chip, 1.5GB of RAM, 16GB of storage, a 2,460 mAh battery, a 13MP rear camera with electronic image stabilization, and a 5MP processor
• Alcatel U5 – a 5 inch phone with a 480p display, an MT6737M chip, a 2,050 mAh battery, a 5MP rear camera with EIS, 1GB of RAM, and 8GB of storage

While the specs for those models are pretty underwhelming, the inclusion of EIS is kind of surprising. And Alcatel describes the A3 as the “most affordable” phone with an HD display, while the U5 is the “most affordable” with 4G support.

The company hasn’t actually said what that will mean though, since prices will vary by region and US pricing details haven’t been released yet.
