How to Change the Language on Your Phone (Android & iOS)
Changing your phone's display language is one of those settings that sounds simple but hides a surprising amount of variation depending on your device, operating system version, and exactly what you want to change. This guide breaks down how it actually works — and what to expect before you dive into the menus.
What "Changing the Phone Language" Actually Means
When people search for how to change the language of their phone, they usually mean one of two things:
- System language — the language used across the entire interface: menus, settings, notifications, and built-in apps
- App-specific language — changing the language inside a single app without affecting the rest of the phone
These are meaningfully different, and confusing them leads to frustration. Most phones now support both, but how you access each setting varies by platform and OS version.
How to Change the Language on Android 📱
Android's approach to language settings has evolved significantly. On Android 13 and later, Google introduced per-app language preferences, meaning you can set your system to English but run, say, a messaging app in Spanish — all natively, without any workarounds.
To change the system language on Android:
- Open Settings
- Tap General Management (Samsung) or System (stock Android/Pixel)
- Select Language or Language & Input
- Tap Add Language to include a new one, or drag your preferred language to the top of the list
- Confirm the change when prompted
The language at the top of the list is what your phone uses by default. The second language in the list typically serves as a fallback — useful if some content isn't available in your primary language.
To change language for a specific app (Android 13+):
- Go to Settings → Apps
- Select the app
- Tap Language
- Choose your preferred language for that app
On older Android versions (12 and below), per-app language support depends entirely on whether the individual app developer has implemented it within the app itself.
How to Change the Language on iPhone or iPad
iOS handles language settings in a similar two-tier way, introduced more explicitly with iOS 13.
To change the system language on iPhone:
- Open Settings
- Tap General
- Select Language & Region
- Tap Add Language under the iPhone Language section
- Choose your language and confirm
Your iPhone will restart to apply the change. This affects the entire system UI, including the keyboard layout, Siri, and date/time formatting.
To change language for a specific app on iPhone:
- Go to Settings
- Scroll to the app in your app list
- Tap it and look for a Language option
Not every app exposes this option — it depends on whether the developer has added localization support and opted into Apple's per-app language API.
Variables That Affect How This Works
The steps above are consistent across most modern devices, but your actual experience depends on several factors:
| Variable | Why It Matters |
|---|---|
| OS version | Per-app language is only natively supported on Android 13+ and iOS 13+ |
| Device manufacturer | Samsung, OnePlus, Xiaomi, and others add custom UI layers that rename or reorganize settings menus |
| App support | The app must be localized into the language you want — not all apps are |
| Region settings | Changing language doesn't always change regional formats (date, currency, units) — those may need separate adjustment |
| Keyboard language | System language and keyboard input language are separate settings |
What Changes — and What Doesn't
Switching your system language immediately affects:
- All system menus and settings screens
- Built-in apps (Clock, Phone, Calendar, Messages)
- Siri or Google Assistant voice and responses
- Date and time display formats (sometimes)
It does not automatically change:
- Keyboard input language — you'll need to add a keyboard under Language & Input settings separately
- Third-party app content — apps pull content from their own servers; a language change won't translate user-generated content or a website's backend
- Regional settings — currency, measurement units, and date formats often live under a separate "Region" setting
When Languages Don't Appear or the Option Is Missing 🔍
A few common reasons the setting might not behave as expected:
- Managed/enterprise devices — phones issued by employers or schools are often locked to specific language configurations by an IT policy
- Region restrictions — some languages are only available if your device's region is also set to a matching location
- Older budget Android devices — some entry-level phones ship with a limited language pack, particularly if they were manufactured for a specific regional market
- Custom Android ROMs — third-party firmware may not include the full Google localization stack
The Layer Most People Overlook
There's a distinction worth noting between display language and input language. You might want to read your phone in French but type in English — or vice versa. These are completely independent settings on both Android and iOS, managed separately under language and keyboard configuration menus.
Some users also want to change the language in which voice assistants respond. On both Siri and Google Assistant, voice language is set independently from the system display language — usually inside the assistant's own settings.
What the right combination looks like depends entirely on how you use your phone day-to-day, which languages you're working between, and whether you want a partial change or a full system switch.
