I updated the security patch for Oreo 8.1 on 1st June 2018. Suddenly since yesterday the Jio Volte calling won't work and I am forced to use the Jio4G voice application to make and recieve calls.
On enquiring with Jio, I was told that this is a software problem from the recent update and the sim doesn't register the IMS status in the APN.
I tried tweaking the APNs bearer setting but Oreo doesn't have a save or Ok button to change the bearer to LTE. Wonder why is that.
Has anyone experienced similar issues. Is there a resolution for this?
