There is a documented language-specific exception: Samsung Japan says Japanese predictive text cannot be toggled on or off on Android 16 and later, even though the setting remains visible. Its guidance distinguishes Android 15 and earlier; this restriction should not be assumed to apply to other languages or regions. Read Samsung Japan’s guidance.
