Pretty much my feeling.The problem of shouting occurs when the caps lock key stays on for the entire note. That turns people off.
This can be extremely frustrating to very embarrassing. Sometimes it pays to turn off auto correct especially if misspelled words remain highlighted. Ive had text turned into complete gibberish so I feel your pain.Unfortunately I am also getting annoyed at auto spell checking and word substitution. My typing skills are weak so I expect to go back and fix typo problems when I reread the message. I really don't need this new level of automation that changes the meaning of my messages.
I'm sure that there is productivity for someone and that's good but I'm not that person.
What is even more frustrating is that these autocorrect features will learn your misspellings and after a bit accept them as correct, that right there is enough to cause one to smash a perfectly good keyboard.
