For use exclusively with Wacom One pen tablets CTC4110WL & CTC6110WL on Android 8-13. FOR ANDROID 8-13 ONLY: The screen of your Android device has a different proportion than the drawing area on your Wacom One pen tablet. Without the Wacom Center App, the drawing displayed on the screen may look distorted from your pen strokes on your Wacom One pen tablet. Wacom Center app calculates the exact size of the Wacom One drawing area needed to assure distortion-free drawing, and adjusts the drawing area accordingly. The rest of the tablet area will be inactive. On most Android devices, you can choose between three options for the drawing area location. You can enjoy your drawing now. Note: Virtually all Android 8-13 devices must be used in portrait orientation when using a pen tablet like Wacom One pen tablet. Pen tablet input in landscape orientation or Desktop mode is not supported by Android 8-13. FOR ANDROID 14 & LATER: This app is not required on Android 14. Android 14 automatically assures distortion-free drawing in all device orientations. To connect via Bluetooth, pair your pen tablet in the Android system settings. If you installed Wacom Center on Android 14 & later, you can uninstall it again.
