Hello
I have the Stadia controller connected to my mobile by usb c, it works well but I do not notice any vibration, is it normal?
Thank you
Normally you should feel vibration. Can you try to see in the ingame-setting of the game that you're playing on mobile if there is any option to enable that allows the controller vibration?
In case there is no ingame-option, you can try the troubleshooting steps for your controller in this article, maybe your controller is just not responsive in this way, but try again after each TS step to see if that solved the issue.
Vibration only works if the stay controller is connected via WiFi, but if it is connected by the usb cable it is not.
I have the same issue.
