Hello Everyone, I’m a new user to this forum, and it’s my first post.
Like @ujjal_babu mentioned above, even me facing the same issue even after turning off sleep standby optimization.
❗For Jio users, VoNR/VoLTE is very basic and CRITICAL for voice calling, as this network is pure LTE and hence does NOT have fallback to 3G/2G for calling. Also at times, phone goes into ‘Emergency Calls Only’ mode. Need to turn Airplane Mode ON and OFF.
Was surprised to see that a fix for this issue was not present in the recently released hotfix. This should have been one of the topmost priorities than anything else. Anyway I hope the Tech Team is aggressively testing this and release another hotfix soon.
Thanks.
