This Wacom Center app ensures optimal performance for Wacom One pen tablets (models CTC4110WL & CTC6110WL) on Android devices.

Android 8-13:

Because Android devices and Wacom One tablets have different screen aspect ratios, drawing without this app may appear distorted. Wacom Center solves this by precisely calculating and adjusting the active drawing area on your tablet, eliminating distortion. The remaining tablet area will be inactive. Most Android devices offer three options for positioning this active area. Note: Portrait orientation is required for use on virtually all Android 8-13 devices. Landscape or desktop mode isn't supported.

Android 14 and later:

This app is unnecessary. Android 14 automatically corrects for distortion regardless of device orientation. To connect via Bluetooth, simply pair your pen tablet in your Android system settings. If you've already installed Wacom Center on Android 14 or later, uninstall it.
