iOS 4.3 has a problem with typing words

This month there were some rumors on the internet indicating that iOS 4 would have problems with typing words correctly, but I didn't give them much importance until now when I realized that iOS 4.3 has a problem with typing words. From Safari I tried to write a comment on this site and I noticed that the phone was entering letters/signs that I did not type on the keyboard. For example, I was using the keys in the picture to write something and when I pressed V a dot appeared instead of letters, the situation was repeated with P instead of I plus a few other letters appeared out of nowhere there. I wasn't using any application from the AppStore so I could say that it was to blame, but I was using Safari that comes with iOS 4.3.

I didn't believe the rumors until today when I experienced it and probably many of you didn't have such a problem with iOS and won't believe what I write here, but are there people among you who had similar problems with iOS 4? How did they manifest?

Below is a video publicat by me last year in which a similar problem is exemplified on iOS 4.2.1.
