Does a change there improve something?
And sometimes the function page forward needs two taps, the first seems to awaken the device (and one thinks nothing happens) and the second actually turns the page.
Lock Keyboard after is set to off and Power down after is set to 20 minutes. In the beggining it was set to lock after 10 min. and I had already changed it into off, but it does not fix the problem.
