Xperia Mini/pro :: Auto Correction Cannot Be Turned Off?

On the Sony build of Android 4.0.4 (all Builds!) on a German "SK17i", the settings for turning off the auto-correction for punctuation is plainly ignored.That is: "Automatical Upper- Lower case" is UNchecked, "automatical replacement" is UNchecked and also in the XPERIA keyboard setting I changed the word suggestions to "never help with typing, do not suggest".And STILL, every time there is a full stop the phone starts the next word at upper case (also at places like "e.g."). If I hit upper case at the beginning of a sentence or after an abreviation, as I am used to with a QWERTZ keyboard, it switches to CAPSLOCK FOR ALL FOLLOWING words in that textbox.It is not even consistent in doing so: when entering a title for an appointment, the phone "Upper Cases" Every Word There Is And Switches To CAPSLOCK When Pressing Shift One Time Regardless Of The Punctuation.It is so annoying I sometimes want to smack the phone to the wall and grab my old Palm Pre which just works like it should, that is like a regular keyboard.I consider this to be a serious bug as the software is clearly IGNORING the system settings.
