Turn Keyboard Character Preview On or Off auf Samsung
The Samsung Keyboard shows an enlarged copy of every key you tap by default. This character preview is meant to confirm your input, but on smaller phones or during fast typing it can cover the text field or slow down the rhythm of typing.
The setting lives inside the keyboard's touch feedback options, separate from sound and vibration feedback. Turning it off removes the pop-up entirely, while typing itself works the same way.
Menu path
Tap on Settings ➔ Tap on General management ➔ Tap on Samsung Keyboard settings ➔ Tap on Swipe, touch, and feedback ➔ Tap on Touch feedback ➔ Enable or disable Character preview
If you still want visual feedback but without the enlarged key, check the other options under Touch feedback, such as key highlighting. If typing feels inaccurate after disabling the preview, re-enable it temporarily to check finger placement, then turn it off again once you are used to the keyboard layout.
