Google turned to bing on my iPhones Safari?

My iphone randomly changed the safari home from google to bing and I absolutely hate bing. How do I change it back? I tried typing in google and using that but it always brings me back to bing if I open a new tab. My brother tried on his phone and he still has google and on the family iPad we have google still please help!

Settings - Safari and change the search engine from Bing to Google.
