My S7 Edge cannot vibrate after opening up just the back
Hi, I've removed the back glass and the flat plastic puzzle like pieces right under it (like wireless charger, etc.) and now when I turn on the phone it cannot vibrate at all. I go to the testing menu by dialing the code and test the vibration part and nothing happens, absolutely no movement. What did I break? I simply removed the back, screws and plastic flat pieces. Those aren't the vibrating motor??? I didn’t touch anything else, no motherboard, no camera, no nothing.
