Good morning, it's Sunday, October 11th, 2026, and this is your React Native briefing.
The throughline today is remount reliability: two fixes tackle lists that silently stop updating after Strict Mode or Activity remounts.
In the first, PR 58985, Virtualized List clears its batch timer on unmount but leaves the timer ID in place. Since Strict Mode in development and the Activity component now unmount and remount the same instance, the scheduler thinks a timer is still running and never schedules another render, leaving new cells…
Separately, Android text scaling gets a correctness fix in PR 58982. The max font size multiplier capped glyph size but not line height or letter spacing, so at high system scales lines kept growing while text did not — one example showed a 20 point line height rendering at 34 density pixels. For developers shipping…
Beyond the list pair, the changes today are independent, not part of a single rewrite.
Finally, PR 58987 adds a use screen dimensions hook, the screen equivalent of use window dimensions. Instead of reading screen metrics manually and managing a change subscription, components get width, height, scale, and font scale that update automatically,…
