Modular phones once seemed like a bright idea. They promised that you could swap parts for a better camera or an extra battery. You could fix a broken screen at home or add a new speaker. Big companies and small teams tried to build these phones. Yet most of us still buy set-in-stone models that we cannot open.
The Rise of Swappable Parts
In the mid-2010s, many designs appeared. A popular concept called Phonebloks asked people to connect blocks together. Each block held one part of the phone. Then Google took up the idea with Project Ara. Moto and LG built their own towers of parts. Fairphone from the Netherlands saw value in easy repair to cut waste. Each team showed how you could add or remove bits in seconds.

What Makers Hoped To Achieve
The inventors saw four big benefits. First, users could upgrade only the parts they wanted. A new camera, better memory, or extra sensors would fit right in. Second, broken pieces could be swapped without tossing the whole phone. Third, green champions praised less waste and longer use. Fourth, tech fans dreamed of endless customization for work or play.
Why Buyers Did Not Bite
After all that promise most phones remain sealed. The first hurdle was cost. Swappable parts and the connectors make the phone thick and heavy. Each module needs a separate battery or wiring. That raised prices well above standard models. Few people wanted to pay more for a niche gadget.
Next, most users want the basics to work every time. They do not want to pick which part must stay or go. They fear voiding warranties or mismatches. They want phones to look and feel the same in hand.
Finally, upgrading major parts like the main chip or modem never landed. The key speed-boosting components stayed soldered. That cut out the most powerful reason to modularize.
The Manufacturers’ View
Big phone makers rely on yearly upgrades. They love it when we replace old models with new handsets. Swappable modules could undermine that cycle. If people only changed the camera block, they might hold onto the rest of the phone for years. That might harm the sales of full phones.
Smaller brands like Fairphone still sell to a loyal few who care about repair. They manage spare parts and software updates for longer. Yet their share remains tiny compared to giants like Apple and Samsung.

The Right To Repair Moment
Today, many governments and user groups push for repair rights. That may help bring back easy swap parts. New laws might force makers to offer spare modules or guides. This would give people more choice and cut down on waste.
As rules change and new ideas emerge, we may see a fresh modular wave. For now, most of us will stick to a single chassis and let the apps do the customizing.
