This happens when I am on WiFi or cellular. I have changed the SIM and it was okay for a few hours and then back to the same thing. The technician from my carrier had me change the SIM after multiple resets. So on my plan I have a Galaxy S9 and 4 IPhone XR and a iPhone 11max none of these phones have the issue I have with my phone. I want my Galaxy S10 back😩😷😒.
