Turn On/Off Auto-space After Punctuation auf Android
Auto-space after punctuation is a Gboard text-correction feature. It automatically inserts a space once you type a period, comma, or other punctuation mark, saving you a manual tap on the space bar.
The option is still labeled as beta and currently only works when your keyboard language is set to US English. If your input language differs, the toggle may be visible but will have no visible effect on your typing.
To change the setting, open Tap on Settings ➔ Tap on System ➔ Tap on Keyboard ➔ Tap on On-screen keyboard ➔ Tap on Gboard ➔ Tap on Text correction ➔ Enable or disable Autospace after punctuation.
Turn the toggle on if you want Gboard to add the space for you automatically. Turn it off if you type fast and often add your own space right after punctuation, since the automatic insert can then create a double space or interfere with autocorrect timing.
If your language is not US English, look for a language-specific text-correction setting instead, since the global toggle will not apply.
