Unhappy [Q] Problems when typing texts

When i type texts mid type the screen flashes up a problem and im bumped out of the individual view and out into the general contacts view. its very annoying and happens a good 70% of the time

FYI Im using the stock android keyboard.

Anyone experienced this and know how to gix it?
