Traditional T9

TT9 is a Nokia-style 12-key T9 keyboard for Android. It provides predictive text input in 40+ languages, configurable hotkeys, clipboard support, undo/redo, and extensive customization options. It works on touchscreens, physical keypads, and TV remote controls. Best of all, it doesn't spy on you!

⚙️ System Requirements

- Android 5.0 or higher. - Storage space varies by Android version. The lite version requires at least 6–8 MB; the full version requires at least 220 MB. - Extra storage is needed for language dictionaries in Predictive Mode: - Languages with character predictions only (e.g., Korean): ~1 MB per language. - Tiny languages (<100k words; e.g., Kiswahili, Indonesian, Vietnamese): 5–6 MB per language. - Small languages (100k–400k words; e.g., English, Norwegian, Swedish, Finnish, French): 15–30 MB per language. - Medium languages (400k–800k words; e.g., Chinese, Danish, Greek, Italian, Portuguese): 40–75 MB per language. - Large languages (800k–1.6M words; e.g., Arabic, Bulgarian, Hebrew, Japanese, Romanian, Spanish): 100–170 MB per language.

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

⚠️ Compatibility

If you have a phone running Android 4.4, use TT9 v44.0 at most. For devices with Android 4.3 or earlier, refer to the original Traditional T9 from 2016.

TT9 may not work well on TCL Flip 2, Kyocera phones (especially those running Android 10 or newer), or other devices with highly customized Android versions where apps are integrated with the native keyboard. You may encounter missing functionality, empty gaps/misaligned items on screen, or unexpected text/numbers when typing.

Compatibility has been verified only on these devices:

- Motorola g05 (Android 15) - CAT S22 Flip (Android 11) - Unihertz Atom L (Android 11) - Qin F21 Pro+ (Android 11) - Energizer H620SEU (Android 10) - Sonim XP3800 (Android 8.1) - Vodafone VFD 500 (Android 6.0)
