Samsung has quietly expanded its mobile accessories lineup with a compact, tenkeyless keyboard designed to work seamlessly across phones, tablets and laptops. Dubbed the Samsung Smart Keyboard (EJ-B7800), it promises multi-device convenience, DeX compatibility and a handful of AI shortcuts — all in a slim aluminum body.
Three-device pairing and quick switching
The Smart Keyboard uses Bluetooth 5.4 to maintain connections with up to three devices at once. A dedicated switching key cycles through paired hosts, with tiny LEDs above the key showing which device is active. There’s no 2.4GHz dongle option, so everything runs over Bluetooth — ideal if your desk setup already relies on wireless display modes like Samsung DeX.
Designed for DeX and modern multitasking
Samsung included a dedicated DeX button, and the F1–F3 row can be repurposed as app shortcuts. Those features require One UI 8.0 or later, so they’re targeted primarily at newer Galaxy phones and tablets — the kind of devices people are likely to dock into monitors for a desktop-like experience.
AI and cross-platform helpers
There’s an AI key on the keyboard too. On Android devices it triggers either Samsung Bixby or Google Gemini depending on your configuration; on Windows PCs the same key summons Microsoft Copilot. It’s a neat way to access assistant features without reaching for your phone.
Specs, battery and build
- Form factor: tenkeyless, 4.3mm profile with an aluminum finish
- Weight: 218 g; key pitch: 19 mm
- Connectivity: Bluetooth 5.4, up to three simultaneous pairings
- Battery: single CR2032 coin cell (Samsung markets it as providing long life, but offers no concrete runtime)
The CR2032 choice keeps the keyboard thin but raises practical questions. Many users prefer AAA cells (especially rechargeable ones) for longevity and easy swaps. And while the keyboard can hop between three devices, you’ll still need a multi-host mouse to match that convenience — Samsung isn’t offering a companion mouse, which undermines the cross-device workflow for some setups.
Availability and price
The Samsung Smart Keyboard (EJ-B7800) is rolling out across several regions. Pricing examples include $110 in the US, €100 in Italy and HKD 1,000 in Hong Kong, with Canada, India and other markets listed as coming soon. It’s positioned as an affordable, sleek option for Galaxy users who want a compact keyboard that plays nicely with phones, tablets and PCs.
Practical caveats remain: the lack of a dedicated dongle, the non-removable coin-cell preference and the missing matching mouse mean Logitech and other multi-device peripheral makers still hold an edge for power users. For anyone building a simple DeX station or wanting a slim keyboard to move between a phone, tablet and laptop, Samsung’s new entry is worth a look.
