When I use a Galaxy Note together with an Apple Wireless Keyboard, pressing Shift+Space switches keyboard layout. This is really annoying. Is it possible to disable it?
Russian Keyboard is a free app that allows you to choose different layouts (languages) for the hardware keyboard and the combination for switching between them (Alt+Shift, Alt+Space or Shift+Space).
Works perfectly on my Samsung with Android 4.4 KitKat.
Note that selected layouts and the switching combination works as long as the app is selected as a current input method.
I have the same issue with the Samsung Galaxy S5 and a bluetooth keyboard. I was able to install Gboard (google keyboard from the app store) and this fixed the problem.
Switching to any other keyboard application as the default should solve this problem, for example SwiftKey. The shortcut exists in the Samsung keyboard and is not possible to turn off.
You can try ctrl+shift. This option better works for the XP. May be it can also work with you.
