[Sm170485]

Hi. 
Just bought s21u; would like to check how do I turn off or disable language name/identifier on samsung keyboard spacebar? Went through the setting but seems can’t find it. 
anyone can help?

Hi. not sure this is possible as the spacebar is used to switch between languages, if you type in more than one on your phone.

that is true and there is a button on the right of the spacebar
