Hey Nick, hope all is well. Which model phone do you have and is there any damage to the buttons at all?
If you hold the 'Power' button and the 'Volume Down' button together, does your phone restart?
Has the situation now changed @Nick300
i.e is everything OK now ?
If not a Samsung Experience Store or Samsung Service Centre can take a look.

The advice I offer is my own and does not represent Samsung’s position.
