Yep. Same problem here. Vibration is absurdly weak. Never have I ever had a device with such terrible vibration on any phone! Cannot be felt when the device is in pockets. Created a topic myself here: https://nothing.community/d/25647-dreadful-vibration-nothing-phone-2a , but the same is waiting approval for two days now.
Submitted a feedback through the device as well, and got a rather annoying parrotic reply which I have attached here.
They are not serious in fixing things apparently. Cheaping out on basic things such as this is disgusting.
