I've updated my HTC Desire HD A9191 to Android 2.3.3 and now I don't know how to get rid off the spelling check (red dotted underline) when text messaging. The underlining isn't present when typing in Evernote's application, for example. It is strictly text-messaging issue.
There's no spelling-check option in message settings. I've tried turning on and off spelling check under
Settings->Language & Keyboard->Touch Input->Text input->Spell correction and it didn't do anything either way. I don't have enabled neither 'Prediction' nor 'Word completion'. Google search didn't find anything about red dotted underline on Androids either.
Why would I want to disable spelling check? Androids don't support my locale the way they should (QWERTZ instead of QWERTY), so I'm forced to use German locale. Which is fine, I'd use English as a system language anyway. But the spelling check is underlining non-German words, which is obviously annoying to me as a non-German native speaker.
