On a big pull request in the mobile app, files already marked Viewed stay in the file list and the diff, so you keep scrolling past them to find what's left. This is the mobile half of #31163, which adds the same filter to the web Code tab.
Change
Adds Hide viewed files beside Hide test files, using the same saved-preference and filter shape as the test-file filter.
The option is in the file list's filter menu, the file picker sheet, and the diff screen menu. It only shows where viewed marks exist (not for a single commit's diff) and once a file is viewed or while the filter is on, so it can always be turned off.
The choice is saved in mobile preferences as pullRequestHideViewedFiles, next to pullRequestHideTestFiles.
The viewed count is taken after test files are filtered out, like on web.
A file you open from another screen (Discussion, Guide, the review sheet, a link), a file with a pending review comment, and a file you mark viewed on the diff screen all stay visible. That last one stays until you leave, so marking a file never pulls it out from under you or shifts the scroll.
If everything is filtered out, the screen says "All files are hidden." with a Show viewed files button.
Opening a file from Discussion, Guide or the review sheet now keeps that file visible under Hide test files too. Before, a hidden test file opened the first visible file instead.
Scope and approval
Same proposal as #31163 (Ideas discussion #30891). It's a filter over viewed marks and the existing test-file filter, and doesn't change how viewed marks are stored or synced.
Verification
pullRequestFileFilters.test.ts: a new case checks which viewed files are hidden and which stay (the opened file and a file with a draft), and that the diff object is reused when nothing is hidden. All 5 tests in the file pass.
Not checked on a device. This Mac has no iOS simulator runtime, so there are no screenshots yet. Worth a look on a device: the scroll position when viewed marks load late, and the eye.slash menu icon on Android.
Written with Claude Opus 5.5 in Claude Code, run from T3 Code.
Reviewing a big pull request on a phone meant scrolling past every file you had
already read. The changed-files list, the file picker sheet, and the diff screen
now have a "Hide viewed files" filter beside "Hide test files", saved as a
mobile preference.
The filter shows only where viewed state exists (not for single-commit diffs)
and only once a file is viewed or while it is on, so it can always be turned
off. A file you mark viewed on the diff screen stays until you leave, as does
the file a link or guide jumped to. When every file is hidden, an empty state
offers "Show viewed files".

Macroscope's review found this PR approvable — Adds an optional mobile filter for viewed pull-request files, with hidden-file counts and controls to show them again. Files remain visible by default, and filtering does not alter repository content or viewed status.
You can add or adjust custom eligibility rules. Learn more.
The mobile pull-request diff now supports hiding viewed files. The filter retains included, drafted, and locally toggled files. Menus, counts, navigation, and empty states reflect the viewed-file filter.

Summary
Filtering rules and preference apps/mobile/src/persistence/mobile-preferences.ts, apps/mobile/src/features/pull-requests/pullRequestFileFilters.ts, apps/mobile/src/features/pull-requests/usePullRequestFilesViewed.ts, apps/mobile/src/features/pull-requests/usePullRequestFileFilter.ts, apps/mobile/src/features/pull-requests/pullRequestFileFilters.test.ts
Preferences now include a sanitized viewed-file filter setting. Filtering identifies viewed paths, retains included, drafted, and locally toggled files, and removes other viewed files when enabled. Tests cover viewed-path classification and filtering.
Route filtering and file jumps apps/mobile/src/features/pull-requests/PullRequestRouteScreen.tsx
The route passes viewed-file state and draft paths to the filter. File jumps track both filter settings, and either filter toggle preserves the visible file path. The route shows an empty state when viewed-file filtering hides all files.
File-list controls and summaries apps/mobile/src/features/pull-requests/PullRequestFiles.tsx
File menus conditionally offer “Hide viewed files.” Summaries report viewed-file counts, and the empty state offers “Show viewed files.”

Merge Risk: Low · up to 2662f
Enabling a file filter from certain menus can jump the reader away from the file they are viewing. The failure is limited to scroll position and self-recovers, so the change is mergeable with these follow-ups.
