Traditional T9

TT9 is a 12-key T9 keyboard for devices with a hardware numpad. It supports predictive text typing in 30+ languages, configurable hotkeys, and an on-screen keypad that can turn your smartphone into a Nokia from the 2000s. And, best of all, it doesn't spy on you!

This is a modernized version of the original project by Clam-.

If your phone does not have Google Play and does not allow installing custom APKs, please consult the Installation Guide. ?? System Requirements

Android 5.0 or higher. A hardware keypad or a keyboard. For touchscreen-only devices, an on-screen keypad can be activated from the Settings. Storage space depends on the Android version. The lite version requires at least 5-8 Mb and the full version requires at least 160 Mb. Extra storage space is necessary for language dictionaries in Predictive Mode. Languages with character predictions only (Korean): ~1 Mb per language Tiny languages (< 100k words; Kiswahili, Indonesian, Vietnamese): 5-6 Mb per language. Small languages (100k-400k words; e.g. English, Norwegian, Swedish, Finnish, German, French): 15-30 Mb per language. Medium languages (400k-800k words; e.g. Danish, Greek, Italian, Portuguese): 40-75 Mb per language Large languages (800k-1.5M words; e.g. Arabic, Bulgarian, Hebrew, Romanian, Spanish): 100-165 Mb per language

Storage usage for the dictionaries depends on the word root count and the average word length in each language. Some languages will require more space, even if they have fewer words than others. ?? Compatibility

TT9 may not work well on TCL Flip 2, Kyocera phones, especially ones running Android 10 or newer, or other devices that run highly customized Android versions, where all apps are integrated and intended to work with the respective native keyboard. You may experience missing functionality, empty gaps/misaligned items on the screen, or unexpected text/numbers appearing when you try to type.
