Thanks for this. Scaling Android controls along with the Appearance text size makes sense, and the device evidence is thorough. Before merging, a few accessibility regressions and some gaps in coverage need fixing.
1. Keep the 48dp touch-target minimum on menu rows. Scaling icons, text, padding and menu width is fine, but 48dp is the Android accessibility minimum (Accessibility Scanner flags anything smaller) and the Material 3 menu-item height. Right now rows drop to 33dp at 11pt. Because the rows touch each other, Compose can't enlarge their touch areas without overlapping. Please clamp the minimum height to 48dp. Most of the "menu looks too big" problem comes from the 250dp width and the padding, and those can keep scaling. Please also update the description: it currently says menu rows can shrink below 48dp.
2. Restore disabled semantics on custom menu rows. Moving from DropdownMenuItem to Row plus clickable means a disabled item just has no click handler. TalkBack now reads it like plain text, without saying "disabled" and with no button role. Please keep the item's enabled/disabled state and role visible to accessibility services.
3. Scale the remaining Android icons, or narrow the scope. Some controls next to ones this PR scales still use fixed sizes:
ControlPillicon+label pills keep a 16dp icon. In the composer, the attachment+and icon-only pills shrink, but these don't.MaterialButton.androidkeeps an 18dp icon while its label scales.MaterialListRowkeeps a 16dp chevron.
Please scale these too, or say in the description that the PR only covers headers, menus and FABs, so the inconsistency is a known follow-up. Switches, radios and segmented buttons can stay fixed; Material keeps those constant.
Non-blocking: some scaled sizes are rounded (Math.round(20 * scale)) and others aren't (18 * scale, 24 * scale, 17 * scale in MaterialSearchField and ScreenHeader.android). Fractional-dp icons can render slightly blurry, so round them consistently. Named sizes from resolveAndroidControlSizing would be clearer than scattered N * scale values.

This should keep the 48dp floor, like buttonSize and fabSize: Math.max(48, Math.round(48 * scale)). At 11pt it resolves to 33dp, below Android's minimum touch target, and adjacent rows can't expand their touch areas without overlapping. Please update the 11pt case in the test to match.

Removing clickable for disabled items drops the disabled state and button role that DropdownMenuItem used to expose. TalkBack will read the row as plain text. Please keep the row clickable with its enabled state passed through (or add equivalent semantics), so assistive tech still reports "disabled".

What Changed
Android headers, icon buttons, floating actions, and menus follow the text size in Settings → Appearance. The home logo, connection heading, search fields, and composer icons use the same scale. iOS sizing is unchanged.
Existing native components retain their styling, interaction, and animation. Menu width, icons, and text scale together; native menu rows keep their spacing and grow for wrapped labels. Native typography presets retain letter spacing while explicit font size and line height follow the app setting.
Icon buttons and menu rows keep a minimum 48dp touch target. Native icon buttons fill that area, including at 11pt; their icons continue to scale down. Filled button backgrounds share that minimum. Header and inline search controls reserve the minimum even where the previous default was smaller. Header height and padding scale while preserving safe-area insets and room for title/subtitle text, and search overlays use the same geometry.
Collapsed New thread and Filter buttons have matching widths. Floating-button placement and list padding account for their size. New thread mounts once its available width is known and releases its label's touch area as collapse starts, preserving taps on the list beneath it. Pill icons, loading indicators, list chevrons, and composer controls use consistently rounded icon sizes.
Why
Reducing the app's text size left Android controls disproportionately large. Shared sizing keeps them proportional while native buttons and menu rows preserve their interaction and accessibility behavior.
Verified on a physical Xiaomi with a release build at 11pt, 16pt, and 22pt. Coverage includes menus, headers and search, the home logo and reconnecting heading, composer controls, native New thread collapse/expand, and taps beside the collapsed button. Header bounds match before and after the touch-target fix at all three sizes, and taps near all four edges work at 11pt. Mobile TypeScript, targeted lint, and focused sizing and scroll tests pass.
