Allow Android tablets to rotate

[juliusmarminge]

What Changed

Added an Expo config plugin that enables Android tablets with a smallest width of at least 600dp to support all orientations while keeping phones locked to portrait.

Why

The app's top-level portrait orientation setting currently locks Android tablets to portrait. This mirrors iPad behavior by allowing tablet rotation while preserving the existing portrait-only behavior on phones.

Note

Low Risk
Scoped Android native MainActivity orientation logic with idempotent plugin injection; no auth, data, or API changes.

Overview
Adds withAndroidTabletOrientation, a new Expo config plugin registered in app.config.ts, so Android behavior matches iOS: phones stay portrait-only while tablets can rotate.

At build time the plugin patches MainActivity to call applyTabletOrientation() after onCreate and again in onConfigurationChanged. When smallestScreenWidthDp >= 600, it sets requestedOrientation to SCREEN_ORIENTATION_FULL_USER (overriding the manifest portrait lock); otherwise it forces portrait. Fold/unfold on foldables re-applies the same rule without requiring an activity restart.

Note

Allow Android tablets to rotate freely while keeping phones in portrait

• Adds a new Expo config plugin withAndroidTabletOrientation.cjs that patches MainActivity.kt at build time to inject orientation logic.
• At runtime, devices with smallestScreenWidthDp >= 600 (tablets) use SCREEN_ORIENTATION_FULL_USER, respecting the system auto-rotate setting; phones stay locked to portrait.
• An onConfigurationChanged override re-evaluates orientation on each configuration change, covering foldable devices.
• The plugin is registered in app.config.ts and skips patching if already applied.

📝 Walkthrough

Walkthrough

The mobile app registers an Expo config plugin. The plugin modifies Kotlin MainActivity to allow user-selected orientations on tablets while preserving manifest portrait behavior on phones.

Approvability

Verdict: Needs human review

This PR enables new user-facing behavior (screen rotation) on Android tablets that were previously locked to portrait. While well-implemented and following existing plugin patterns, new runtime capabilities that change user experience warrant human review.
