PROFILE
Jannick Fahlbusch
Over a two-month period, contributed to koreader/koreader by developing features focused on device orientation and user configurability. Implemented cross-device screen orientation synchronization for PB700 and Pocketbook Era Color, introducing an orientation_sync flag and streamlined rotation logic to improve stability during suspend and resume cycles. Enhanced user control by adding an input_ignore_gsensor setting, allowing users to bypass gyroscope-based rotation fixes and reduce unintended rotations. These changes were delivered using Lua for device firmware and embedded systems programming, with careful attention to event handling and user settings management. The work emphasized maintainability, configurability, and consistent user experience across supported devices.

Apr 1, 2026Month: 2026-04 — Koreader/koreader: Delivered a user-configurable GSensor/gyroscope rotation control improvement. Added input_ignore_gsensor setting that, when enabled, routes gyroscope events through a void handler to skip the rotation fix, giving users direct control over device behavior. Implemented via commit 1466c1a9fd9b3d81a66a86de69937c8a8ebfda96 and aligns with issue #15304. No major bugs fixed this month; focus was on configurability and robustness. Impact: higher user satisfaction, fewer unintended rotations on devices with varying GSensor behavior, and easier maintenance through explicit config-driven behavior. Technologies/skills: sensor event handling, config-driven feature flag, code maintainability and clear commit history.

Jan 1, 2026January 2026 monthly summary for koreader/koreader: Implement cross-device Screen Orientation Synchronization on Resume and Hibernate for PB700 and Pocketbook Era Color, introducing an orientation_sync flag and simplified rotation handling to improve user-visible stability during suspend/resume. Fixed auto-orientation inversion after suspension across devices, with changes aligned to updated C-bindings and related base PRs. Extended the rotation fix to the Era Color as well to ensure consistent behavior across devices. These changes reduce wake/glitch issues and lay groundwork for per-device tuning and future enhancements.
