@SuzieQboo A Warm Welcome to the Samsung Community Forum. 

Run the diagnostic tool found in your Samsung Members App to see what that says. 

If nothing shows up and your still experiencing issues then either report this back to the merchant i.e who supplied the phone , and or a Samsung Service Centre. 

If i can be of any further help please don't hesitate to ask  😎
