Onyx Boox Note Air 5C will roll out firmware 4.2.1 in a few weeks, adding new pen controls, template hub and NeoReader engine upgrades while fixing bugs.
Onyx Boox confirmed that its latest‑generation Note Air 5C e‑reader will receive the 4.2.1 firmware update within the next couple of weeks, bringing a suite of new note‑taking tools, display tweaks and stability fixes that aim to keep the device competitive against newer Android‑15 tablets [1].
| At a glance | |
|---|---|
| Device | Onyx Boox Note Air 5C |
| Firmware | 4.2.1 (beta now, full release in a few weeks) |
| Major additions | EinWise Code, Image Smoothing, pressure‑sensitivity control, Template Hub, Scrolling view, NeoReader engine upgrade |
| Known issues | DPI settings require app restart, occasional Lasso crash, Google Calendar sync pending, UI glitches in AI Assistant |
The update adds the EinWise Code feature to the EinkWise Center and enables image smoothing in HD or Regal refresh modes, improving visual fidelity on the 300 PPI E‑ink panel [1]. A new pressure‑sensitivity slider for the standard Pen brush gives users finer control, while an auto‑deselect option for the eraser reduces accidental strokes. The freshly introduced Template Hub lets users browse and download note templates directly on the device, and a Scrolling view replaces the default paged layout for smoother note navigation [1].
Under the hood, the NeoReader engine receives a major upgrade that speeds PDF loading, smooths page turns and enhances support for math formulas—benefits echoed in the parallel 4.2 rollout for the Go 10.3 Gen 2 and Lumi models, which also gained a revamped calendar app with Google Calendar sync and a stroke‑stabilization option for the standard Pen brush [2]. Both updates run on Android 15, a step up from the Android 12 base of earlier Boox devices, promising better security and overall performance [2].
Despite the enhancements, the beta notes several unresolved bugs: DPI settings from EinkWise Code configs only apply after restarting the app, the Lasso tool can still crash sporadically, and the Template Hub may be inaccessible until a device reboot or region switch [1]. Cloud‑disk integration quirks persist, with Google Drive sometimes disappearing from the list after first‑time binding, and the AI Assistant UI still shows language glitches [1]. Google Calendar integration for Calendar Memo is slated for a later release, meaning the current upgrade does not yet deliver full cross‑platform scheduling [1].
These fixes arrive as Onyx Boox faces mounting competition from other Android‑based e‑readers that emphasize stylus performance and low‑latency drawing, such as the reMarkable 2 and Kindle Scribe. By bolstering pen controls and NeoReader speed, Boox hopes to narrow the gap, but lingering stability issues could dampen adoption among power users who prioritize a seamless note‑taking experience.
The 4.2.1 update signals Onyx Boox’s effort to keep the Note Air 5C relevant in a fast‑evolving e‑reader market, but the final impact will hinge on how quickly the remaining bugs are resolved and whether the new pen features translate into measurable productivity gains for users.
