@@ -20,6 +20,8 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - **`pz`/`conf` unit labels translated** — "pz" now shows as "pcs" in English and "Stk" in German; "conf" shows as "pkg" / "Pkg". All `unitLabels` objects in JS now use `t('units.pz')` / `t('units.conf')`.
 
 ### Fixed
+- **Camera button (📷) opened kiosk SettingsActivity on Android** — The native `btnSettings` ImageButton in the kiosk layout was positioned `top|end` with `alpha=0.12` (nearly invisible), sitting directly on top of the HTML scan button in the webapp header. Every tap on the 📷 button was intercepted by the native View and opened `SettingsActivity`. Fixed: moved `btnSettings` to `bottom|end` (above the bottom nav bar, `marginBottom=80dp`) and increased `alpha` to `0.28` so it is clearly separate from the header. Kiosk versionCode bumped to 16.
+- **Camera button (📷) opened settings on Android Chrome/Brave** — `pointerleave` fired before `pointerup` when finger drifted slightly, cancelling the long-press timer and leaving the browser to dispatch a synthetic `click` that bubbled to an unintended handler. Fixed: added `setPointerCapture` (prevents `pointerleave` during touch) and `preventDefault` (blocks synthetic click); replaced `pointerleave` with `pointercancel` handler. Added `touch-action: manipulation` to `.header-scan-btn` CSS.
 - **Logo white background on splash screen** — Re-processed both `logo.png` and `logo_icon.png` with fuzz 35% alpha extraction, removing the white background that was visible against the dark splash background (`#0f172a`).
 - **Recipe button label** — Shortened to "Ricetta" / "Recipe" / "Rezept" for compact display in the inventory quick-action modal.
 - **Quantity decimal precision** — `qtyNum` in recipe/cooking ingredient buttons and `conf` fallback display in inventory cards now limited to 1 decimal place (was showing 7+ decimal places from raw AI output, e.g. `0.25353223 conf`).
