Just started recently. Wifi calling and the smart settings are off and wifi set to stay on when screen goes off. Anyone know?
I was having the same issue. Resolved by installing the following app https://forums.androidcentral.com/e...s?id=com.roy.wifimonitor&hl=en&token=gdHEiz85
For the record the setting under wifi for "Keep wifi on when screen is off" was set to Yes and ignore optimization for wifi was enabled, and did not resolve the issue.
Turned these off after installing the app and wifi is still working perfectly thanks to this app. Stopping this app makes the issue return.
