Will your next phone be as customisable as Lego blocks?

Modular phones present a radical departure from this model. Designed for longevity and customisation, these phones allow users to swap out components like the screen, battery and even camera modules, all using standard tools. The result? A phone that evolves with you, rather than expires on schedule.

Finnish manufacturer HMD, best known for producing Nokia-branded phones, is venturing into modular territory with the HMD Fusion. Designed as a midrange device, the Fusion features a 6.56-inch screen, Snapdragon 4 Gen 2 chipset and a removable, modular back panel known as Outfits.
These Outfits, which attach via connector pins, range from basic coloured covers to functional accessories like the Smart Outfit—featuring a flip-up flash powered by the phone—and a Gaming Outfit with dual joysticks and triggers that transforms the Fusion into a handheld console.
HMD has prioritised repairability, using standard screws instead of glue. Users can replace the screen, battery and other internal components themselves. The company has also released a toolkit for developers and hobbyists to design their own Outfits using 3D printing. Fairphone 5: prioritising repairability and ethical sourcing

Dutch company Fairphone has been leading the sustainable smartphone movement since 2013. Its latest model, the Fairphone 5, is engineered for a 10-year lifespan, supported by a five-year warranty and eight years of software updates.
Powered by a Qualcomm chipset and featuring IP54 resistance, the Fairphone 5 is designed with repairability and ethical sourcing in mind. It uses no glue in its assembly, instead relying on screws, so components like the battery, screen, camera modules, USB port and earpiece can be replaced individually.
The phone's body is made from 100 per cent recycled aluminium, and its supply chain prioritises fair trade practices. It ships with a de-Googled version of Android called /e/OS, but users can opt to install other Android distributions—or even Linux. CMF by Nothing: stylish, accessible modularity

CMF, a sub-brand of British tech upstart Nothing, has released the CMF Phone 2 Pro, its second modular phone. Designed with affordability in mind, it is powered by the MediaTek Dimensity 7300 chipset and also carries an IP54 rating.
Rather than overhaul the entire phone, CMF focuses on modular accessories that attach to the back panel. Users can swap in add-on lenses (such as fisheye or macro), magnetic folding stands, or even wallet attachments. An extra thumb screw on the corner allows lanyards or other accessories to be secured. The backplates themselves can be removed with a screwdriver and 3D printed for further customisation. Better phones mean a better future

Despite their promise, modular phones face challenges—chief among them being the trade-off between flexibility and sleek design. Consumer habits, driven by rapid upgrade cycles, also present a barrier to widespread adoption.
However, as environmental concerns gain urgency and regulations around e-waste tighten, modular designs could become the new standard. With brands like Fairphone, HMD and CMF leading the charge, the smartphone of the future may not just be smarter—it may also be more sustainable, more durable and more personalised.
