Enlarge the Mouse Pointer auf Samsung
When you plug in a mouse or touchpad, Samsung devices display a standard pointer sized for typical screen resolutions. On larger tablets or foldables, or if you have limited vision, that pointer can be difficult to spot, especially against busy backgrounds.
This setting lives inside the accessibility tools built for visibility, not inside general display settings, so it is easy to miss on first look.
Where to find the setting
Open Tap on Settings ➔ Tap on Accessibility ➔ Tap on Visibility enhancements ➔ Enable or disable Large mouse/touchpad pointer. Toggling it on immediately resizes the cursor for any connected mouse or touchpad, no restart needed.
If you disconnect the accessory later, the setting stays saved and applies again the next time you connect a pointer device.
If your issue is actually about touch response or a stuck on-screen cursor rather than pointer size, check the connection quality of your accessory first, since a loose Bluetooth pairing or worn USB cable can cause similar visual glitches.
