July 2025 performance summary for bcgov/bc-wallet-mobile: The primary delivery this month was a stability fix for TakeVideoScreen video rendering. By adjusting useCallback/useEffect dependency arrays (removing promptOpacity and over30Seconds from dependencies and ensuring elapsedTime is not a timer start dependency), we mitigated unnecessary re-renders, resulting in smoother video capture and improved reliability. This work, anchored by commit 5cb065eec93b4ddbc74705e79018346ae1614a1b ('fix: send video re render (#2581)'), enhances user experience, reduces CPU usage, and lowers risk of UI jank during video workflows. No new features shipped this month for bc-wallet-mobile; the focus was stabilizing core video capture functionality.
