Space Bar Hold Action auf Samsung
On Samsung phones, a long press on the space bar can trigger a shortcut instead of simply inserting spaces. Samsung Keyboard controls this behavior through a dedicated setting, and it offers three options: No action, Cursor control, and Voice input.
Cursor control turns the space bar into a trackpad for moving the text cursor, which is useful when editing long messages but confusing if you expect a regular space. Voice input starts dictation the moment you hold the bar down, which can be disruptive if you tend to rest your thumb there while typing.
To change the assigned action, go to Tap on Settings ➔ Tap on General management ➔ Tap on Samsung Keyboard settings ➔ Tap on Swipe, touch, and feedback ➔ Tap on Touch and hold space bar ➔ Choose an option.
Selecting No action disables the gesture completely, so a long press just inserts extra spaces. This setting only affects Samsung Keyboard; switching to a different keyboard app resets the behavior to that app's own defaults.
