Modern smartphones have become frustratingly similar, haven’t they? Every flagship device feels like a variation on the same glass rectangle theme, with manufacturers competing on camera megapixels and processor speeds while completely ignoring the tactile satisfaction that made classic phones so memorable. YouTuber Marcin Plaza apparently got tired of this sameness and decided to build something genuinely different by combining a broken Galaxy Z Flip 5 with a BlackBerry Q10 keyboard.
Plaza’s DIY slider phone project has gone viral across major tech sites for good reason, representing both impressive engineering and a nostalgic callback to when phones had personality. The build process involved salvaging components from a damaged Z Flip 5, integrating a physical BlackBerry keyboard, and creating a custom magnetic slider mechanism that echoes classic phones like the Nokia N97. The result runs Android with full keyboard functionality, creating a device that feels both retro and surprisingly modern.

The engineering challenges were substantial, requiring custom PCB work, 3D printing for housing components, and careful integration of two completely different hardware ecosystems. Plaza had to map the BlackBerry keyboard to work seamlessly with Android, design a slider mechanism that feels satisfying to use, and ensure the frankenstein device actually functions reliably for daily tasks. The magnetic slider provides that tactile click that smartphone users have been missing for over a decade.
What makes this project particularly compelling is the pure joy of physical interaction it brings back to smartphone use. Every text message becomes a tactile experience with real key presses, while the sliding mechanism adds a satisfying ritual to answering calls or unlocking the device. The BlackBerry keyboard provides the kind of typing accuracy that touchscreen keyboards still struggle to match, making it genuinely practical for heavy text users despite its unconventional appearance.
However, the practical limitations are obvious from the videos showing the device in action. The combined thickness of the Z Flip and keyboard makes it substantially bulkier than modern phones, while the custom form factor creates ergonomic challenges for one-handed use. App compatibility issues arise with software designed exclusively for touchscreen interaction, and the overall device feels more like an interesting experiment than a practical daily driver for most users.
Plaza’s slider phone reminds us that the best innovations often come from individuals willing to experiment outside corporate boundaries. While this particular device might not be practical for everyone, it proves that there’s still room for creativity, nostalgia, and tactile satisfaction in mobile technology when someone cares enough to build it themselves.
