Samsung’s general Galaxy instructions use these labels, but screens can differ by model, software version, and carrier. If your A12’s menus do not match, search Settings for “Language” or consult the support materials for your exact model and region. Samsung’s language and input settings guide describes the general route and its variations.

Set a different language for one app
Samsung’s instructions for app-specific languages cover Android 13 with One UI 5. On a compatible device, open Settings > General management > App languages, select an app, and choose one of the languages it offers. The option is not available for every app: support depends on the app developer, and software or device configuration may affect whether the menu appears. Samsung’s app-language guidance explains this limitation.

Why the menus may differ between Galaxy A12 phones
Galaxy A12 support documentation is not identical across regions and model variants. For example, Samsung lists Android R 11.0 documentation for the US AT&T SM-A125U, while regional support pages list Android 12 and Android 13 manuals for A12 variants. Those listings do not establish that every A12 received the same Android release. Check your model number and installed Android/One UI version if a setting is absent or labeled differently.
