This is a fairy tale :) thank you very much! In my opinion, the best keyboard :) On the Galaxy S3, the xperia keyboard works fine.
Maybe someone will be useful:
1. Make ROOT (you can find information on the Internet, nothing complicated)
2. Put CWM Manager
3. Run CWM in Recovery mode
4. In the menu that appears, select "install zip from sdcard" (to go through the menu, the volume key (up and down) and to select the lock key on the right)
5. If the file is on the device itself, then select "Chouse zip from sdcard", if on a memory card, then "chouse zip from internal sdcard".
6. Next, select the downloaded zip file.
7. The device goes to reset and the keyboard is available in the menu: settings-language and input. There put a tick near it and set it as default.
if somewhere is wrong, correct :)
I did not want a file from the header, but I ate the file from this message
