For example, the [`FORCE_RESIZE_APP`](/guide/topics/large-screens/large-screen-compatibility-mode#force_resize_app) override instructs the system to resize the app to fit display dimensions even if [`resizeableActivity=\"false\"`](/guide/topics/manifest/application-element#resizeableActivity) is set in the app manifest.\n\nDevice manufacturers apply overrides to apps on select large screen devices.\n\nPer-app overrides are intended to improve the user experience on large screen devices. Apps can disable some overrides.\n\nFor more information about per-app overrides, see [Device compatibility mode](/guide/practices/device-compatibility-mode).\n| **Note:** To enable your app to provide the best user experience without relying on overrides, follow the [Large screen app quality](/docs/quality-guidelines/large-screen-app-quality) guidelines.\n\nDevice manufacturer overrides\n-----------------------------\n\nDevice manufacturers apply overrides to apps to improve the user experience on tablets, foldables, and other large screen devices. For a complete list of overrides, see [Device compatibility mode](/guide/practices/device-compatibility-mode#per-app_overrides).\n\n### Disable the overrides\n\n[`PackageManager.Property`](/reference/android/content/pm/PackageManager.Property) tags enable apps to disable device manufacturer overrides. Android 14 introduces the following tags:\n\n\u003cbr /\u003e\n\n- **PROPERTY_COMPAT_ALLOW_RESIZEABLE_ACTIVITY_OVERRIDES**\n\n To disable the [`FORCE_RESIZE_APP`](/guide/topics/large-screens/large-screen-compatibility-mode#force_resize_app) and [`FORCE_NON_RESIZE_APP`](/guide/topics/large-screens/large-screen-compatibility-mode#force_non_resize_app) overrides, set the property to false in your app manifest: \n\n \u003capplication\u003e\n \u003cproperty\n android:name=\"android.window.PROPERTY_COMPAT_ALLOW_RESIZEABLE_ACTIVITY_OVERRIDES\"\n android:value=\"false\"/\u003e\n \u003c/application\u003e\n\n **Optimize your app for large screens:** Make your app resizable and implement responsive/adaptive layouts for an optimal user experience on displays of all sizes.\n\n \u003cbr /\u003e\n\n- **PROPERTY_COMPAT_ALLOW_MIN_ASPECT_RATIO_OVERRIDE**\n\n To disable [`OVERRIDE_MIN_ASPECT_RATIO`](/guide/topics/large-screens/large-screen-compatibility-mode#override_min_aspect_ratio), set the property to false in your app manifest: \n\n \u003capplication\u003e\n \u003cproperty\n android:name=\"android.window.PROPERTY_COMPAT_ALLOW_MIN_ASPECT_RATIO_OVERRIDE\"\n android:value=\"false\"/\u003e\n \u003c/application\u003e\n\n The property also disables the following device manufacturer overrides:\n - [`OVERRIDE_MIN_ASPECT_RATIO_PORTRAIT_ONLY`](/guide/topics/large-screens/large-screen-compatibility-mode#override_min_aspect_ratio_portrait_only): Restricts configurations that force a given minimum aspect ratio for activities with portrait‑only orientation.\n - [`OVERRIDE_MIN_ASPECT_RATIO_MEDIUM`](/guide/topics/large-screens/large-screen-compatibility-mode#override_min_aspect_ratio_medium): Sets the activity's minimum aspect ratio to a medium value (3:2).\n - [`OVERRIDE_MIN_ASPECT_RATIO_LARGE`](/guide/topics/large-screens/large-screen-compatibility-mode#override_min_aspect_ratio_large): Sets the activity's minimum aspect ratio to a large value (16:9).\n - [`OVERRIDE_MIN_ASPECT_RATIO_TO_ALIGN_WITH_SPLIT_SCREEN`](/guide/topics/large-screens/large-screen-compatibility-mode#override_min_aspect_ratio_to_align_with_split_screen): Enables the use of split‑screen aspect ratio. Allows an app to use all the available space in split‑screen mode, avoiding letterboxing.\n - [`OVERRIDE_MIN_ASPECT_RATIO_EXCLUDE_PORTRAIT_FULLSCREEN`](/guide/topics/large-screens/large-screen-compatibility-mode#override_min_aspect_ratio_exclude_portrait_fullscreen): Disables the minimum aspect ratio override in portrait full screen to use all available screen space.\n\n **Optimize your app for large screens:** Don't set aspect ratio restrictions in your app. Create app layouts that support different screen sizes and multi‑window mode."]]
