I have been facing bad call quality since I have purchased the phone. On regular basis I need to disconnect the call and try again to hear the other person on the call. I used to think this is due to VoWifi but even on Volte mode is pretty bad. I cant even remember a time where I had not faced some kind of network issue while calling. I thought on NO3 these issue would fix but no, issues are still there. I think calling is a basic functionailty of any phone and that needs to be perfect. I also have NP2a but there seems to be no issues with that phone in terms of calling.
Exact Issue: Voice breaking on the call
