This is not related to mobile data...I"ve posted this in another forum here, but just found this one.
On a Galaxy S10, current Android version. Whenever I am on a call and try to use the internet, there is no connection. I will also lose internet on all devices, like my laptop. If I disengage WiFi, it will return to the other devices(it took weeks to figure that out). it happens in all locations. I have Comcast internet, and the tech told me he'd never heard of this (they're not always a lot of help). Anyone else experience this? Is it a setting on my phone? On the modem (altho, as I said, it does it in other locations)?
