Respuesta a "Do I need a new vibrator?"Vibrator may be blocked by the display assembly. Get some free vibration.app, and listen carefully, if there're ticking noises when you run the app. If they are present, you don't need new vibro. In my case i had to press down the vibrator platform, as it had been bent a bit up to the screen (the vibro has little "paws" that must be placed under the battery), and place some tape-padding on the display back near the vibrator head, as it seems that default strips became flattened with time.
