tt9 VS KryptEY

All people a talking about T9 which is better at DuraXE from the box. But all T9 options at Kyocera devices are poor due to some licensing problems. Just sideload "Traditional T9" app and choose specs, not T9 options. See link https://github.com/sspanak/tt9 I think, the Kyocera DuraXV extreme+ is best option.

Just download and install the Traditional T9 (TT9) app here: https://github.com/sspanak/tt9

here's the link to TT9's github release page: https://github.com/sspanak/tt9/releases/tag/v22.0

It can do t9. It has a built-in T9 keyboard, there are also third party ones you can install, such as https://github.com/sspanak/tt9/releases/tag/v22.0

Yes. TT9 is the most popular of the options, and works very well. The 903KC prevents you from selecting any keyboard in the settings besides the default keyboard, but you can override this with adb commands:

I don't have the cat-s22, but do have an android flip with a physical keyboard, my go-to is tt9, which you can find on github, it does have some odd quirks with using it but it does support adding custom words and some symbols, might take a bit to fully understand how to use but hopefully it does work smoothly on yours!

download TT9 for proper T9 on the phone, if you don't you'll be stuck with 3click letter-by-letter typing

How does it work?: https://github.com/amnesica/KryptEY/blob/master/KRYPTEY.md

Should E2EE services be banned in your country with no decent option to evade their authoritarian measures, you can use any unencrypted platform with KryptEY to effectively and privately send messages to your contacts.
