I had similar problems with my new Samsung Galaxy Tab 3. When I wanted to write a post for a forum I got the writing window and the keyboard but when I typed three letters the keyboard vanished and this problem continued. Later I discovered how to really shut down the tablet by pressing the switch-off a bit longer. Then I got a message: Switch off the tablet? I clicked okay. When I turned on my tablet again after some time the trouble with writing was gone.
