How to Change the Language on Your Phone (Android & iOS)

Changing your phone's display language sounds simple — and often it is. But depending on your device, operating system version, and how deeply language settings are layered into your apps, the process can vary more than you'd expect. Here's a clear breakdown of how it works, where to find the settings, and what factors shape your experience.

What "Changing the Language" Actually Controls

When you change the language on your phone, you're typically adjusting the system language — the language used for menus, notifications, settings screens, and built-in apps. This is separate from:

  • Keyboard language — what language you type in
  • Voice assistant language — what language Siri, Google Assistant, or Bixby responds in
  • App-level language — what language individual apps display in

Changing the system language doesn't automatically change all of these. You may need to adjust each one independently, depending on what you're trying to accomplish.

How to Change the System Language on Android 📱

Android's settings structure varies slightly by manufacturer (Samsung, Google Pixel, OnePlus, etc.), but the general path is consistent:

  1. Open Settings
  2. Tap General Management or System (varies by brand)
  3. Tap Language and Input or Language
  4. Tap Add Language if your target language isn't listed, then set it as the default

On stock Android (like Pixel devices), the path is typically: Settings → System → Language & Input → Languages

On Samsung devices running One UI, it's usually: Settings → General Management → Language

Android also supports multiple languages simultaneously. You can add several languages and rank them by priority. The system uses your top-ranked language by default, but apps that support your secondary language may display in that instead.

Per-App Language Settings (Android 13+)

Starting with Android 13, Google introduced per-app language preferences. This means you can set one language for your phone's system and a completely different language for a specific app — without affecting anything else. You'll find this under:

Settings → System → Language & Input → App Languages

Not all apps support this feature yet, but major apps (YouTube, Chrome, Google Maps) increasingly do.

How to Change the System Language on iOS (iPhone & iPad)

Apple's language settings are consistent across devices running the same iOS version. The path is:

  1. Open Settings
  2. Tap General
  3. Tap Language & Region
  4. Tap Add Language to include a new one, or tap your preferred language to move it to the top

iOS will ask you to confirm the change, then restart the interface in the new language. Like Android, iPhone supports multiple preferred languages, and apps will display in whichever language from your list they support best.

Per-App Language on iOS (iOS 13+)

Apple introduced per-app language settings in iOS 13. You can set a different display language for individual apps without changing the system-wide language:

Settings → [App Name] → Language

This only appears for apps that have declared support for multiple languages in their build.

The Variables That Shape Your Experience

Not every language change goes smoothly across the board. Several factors affect how complete and consistent the switch feels:

VariableWhat It Affects
OS versionOlder versions have fewer per-app language controls
Device manufacturerSamsung, Xiaomi, etc. layer custom UIs that can shift menu names
App language supportApps only display in languages their developers have included
Region settingsDate formats, currency, and measurement units are tied to region, not just language
Keyboard setupSystem language change won't auto-switch your keyboard layout

Region and language are not the same thing. You can set your phone to display in French while keeping your region as the United States — which means you'd see French text but US date formats and currency. Or you can change both. This distinction matters if you're learning a language, traveling, or managing a multilingual household.

What Doesn't Change Automatically

When you switch the system language, a few things often stay behind:

  • Third-party apps that only support one language won't change
  • Keyboard language and layout need to be updated separately under keyboard settings
  • Voice input and assistant language have their own settings — usually inside the assistant app itself (Google Assistant, Siri, Bixby)
  • Search and content recommendations in apps like YouTube or Google may still reflect your previous language until you update those preferences too

Multilingual Setups Add Another Layer

If you're setting up a phone for someone who speaks multiple languages, or switching between languages yourself, the ranked-language system on both Android and iOS gives you useful flexibility. The phone tries to serve content in the highest-ranked language it can find support for — but behavior varies app by app. 🌐

Some users run their system in one language while keeping a keyboard active in another, which works fine. Others want everything — system, keyboard, voice, and apps — synced to a single language, which requires checking each setting category individually.

How seamless or fragmented that experience feels depends heavily on which apps you use most, whether those apps are well-localized, and which OS version your device is running. A flagship running the latest Android or iOS generally handles multilingual setups more gracefully than an older device on an outdated OS — but the underlying settings logic is the same across the board.
