No iam on Android 9. OS 9.0.11
Cleared Cache in recovery mode but didn't work. Also tried enabling and disabling Airplane mode.
I tried forget network post changes also issue is same.
WIFI is working in all other devices except phone.
My Wifi is not working. Showing Connected No Internet after system update.
I am facing the same issue. My sim 2 is giving same error, instead calls are active on same sim but mobile data is not working & giving this "!"...
Incoming & outgoing calls voice is not clear. Have to redial the call for better clearity. But same is good with Earphone but awful without Earphone.
