Reset samsung galaxy s (SCH1500)

Hi. I have an old Samsung Galaxy S, Model# SCH1500. I don’t need to use it as a phone, I only want to use it as a camera and for access to WiFi internet on occasion. When I turn it on it keeps giving me a message “THE APPLICATION GOOGLE PLAY SERVICES (process com.google.androids.gms) HAS STOPPED UNEXPECTEDLY. PLEASE TRY AGAIN.” . What can I do to clear the phone so I can use it again?

Thanks.
