Just relax and turn on the app. Test the vibration as much as you want. Connect the gamepad from your console and enjoy.
レビュー
DUALSHOCK4で使用しました 一度振動をオンにすると、タッチしても止められない状態になります。アプリを閉じれば数秒後に止まりますが、少し不便です。 Once the vibration is turned on, it cannot be stopped by touch. If I close the app, it stops after a few seconds, but it is a little inconvenient.
