On some particular Samsung devices, you may encounter a touch inaccuracy issue, which means the touch point is not exact to the position of your finger or cursor. For example, when you touch/click, the exact effective position on the device is offset by about one inch. In this case, you can configure the Splashtop Add-on: Samsung (knox).
Please open the Splashtop Add-on: Samsung app, tap the three dots at the top right corner, tap Remote control injection mode, and change it to other options and try.
Addon supports app configuration to change the value through MDM
