I had the same problem, I do not want to root my device, but I like to use the standard key board from Sumsung. I send a a-mail to a lot of dutch companies (resellers) to tell them about the problem. I think that Sansung must make a firware update to solve this problem. I what to ask all people who have problems with the keyboard to e-mail Samsung and there reseller to put preasure on Samsung to make a firmware.
I use a work a round, I use a 3e party keyboard untill Samsung makes a firmware update.
