VoLTE has always been good for me. So do I choose Reset to Default in APN settings?Can both of you confirm if VoLTE works on your device?
Either via the HD icon showing when you make a call OR dial *#*#4636#*#* > Phone info > 3 dot > IMS Service Status.
hedge can you also try reseting your APN settings?
Nevermind I selected Reset to Default and rebooted. I will let ya know if I notice any changes! Thanks man.
