Can I set google dialer as default in galaxy a5 2017

[Android Central Question]

I downloaded google dialer and installed it I went into default apps and set it to default. I went to show system apps and deleted data cache in Samsung phone as well as deleting default settings however the old app still comes up or when it asks me what app I want to use but does not show google phone. I then went back to default apps it shows checked but it's not there when i choose default apps set default.
