Turn Keyboard Sounds On or Off auf Android
Keypress sound feedback comes from the on-screen keyboard app, not from the general system sound settings. On Android, Gboard manages this feedback on its own, which is why changing media volume or notification sound has no effect on it.
To change this setting, open Settings ➔ System ➔ Keyboard ➔ On-screen keyboard ➔ Gboard ➔ Preferences. Inside this menu, find Sound on keypress and switch it on or off.
Once enabled, a volume slider appears next to the toggle. Use it to set the keypress sound to a comfortable level instead of leaving it at whatever volume it defaults to.
If you use a third-party keyboard app instead of Gboard, this toggle does not apply. Each keyboard app manages its own sound feedback, usually in a similar Preferences or Sound section inside that app.
Keypress sounds can still stay silent even with the toggle on if your phone is in silent mode or if a Focus or Do Not Disturb profile mutes system sounds. Check those settings first if enabling the option produces no audible feedback.
