How to Change Language Settings on Android?
🔧 Steps:

Open the Settings app.

Scroll down and tap System (or “General Management” on some models).

Go to Language & input or simply Languages / Language & region.

Tap on Languages.

Here you can:

✅ To add a new language:
Tap “Add a language” (or “+ Language”), then select your desired language from the list.

📌 To set a language as default:
Drag the added language to the top of the list (or tap the three dots and select “Set as default”).

🗑️ To remove a language:
Tap the three-dot menu or “Edit” option to delete it.

🌍 What Happens When You Change the Language?

• The phone interface (menus, system messages, etc.) changes to the selected language.

• App languages will also change if they support the selected language.

• The keyboard language may not change — you may need to adjust it separately.

⌨️ Changing the Keyboard Language (for Gboard)

Go to Settings > System > Language & input > Keyboard > Tap Gboard.

Then go to Languages > Tap “Add language” to add a new keyboard language.

While typing, press and hold the globe icon or the spacebar to switch between languages.
