Welcome to the forums. Does the same problem persist if you rotate the phone and type on landscape mode? Have you already tried using a different keyboard?

Belatedly... I have the same problem on my old LG Nexus 4, Android 511. The problem for me is with letters X, D and to some extent with R (upper or lower case). Rotating the screen is a workaround, but some apps don't allow that, which is especially annoying when D etc is in a password. Mostly I can rely on the messaging app etc to suggest words but not when it's a password. Problem exists with any keyboard and so I assume there is some mapping area within Android that has been clobbered.
