When I turn on my phone, it starts vibrating, entering wrong patterns, opening Google, emergency dialing, etc. without any input from me. Is there any way to stop this?

More or less you’re dealing with a digitizer/touch issue. Usually occurs when pressure is applied to the unit. Best thing to do is LCD/Digitizer replacement. If you want to ensure that’s the case, take it to a shop and they can test it IF they have the part available.
