Good morning,
I have had a OnePlus 6T A6010 variant since Dec 2018. However after one of the updates (I forgot which), I was suddenly unable to make/recieve calls with the phone. Unless it was through a msging app (whatsapp/telegram).
I understand that there is a way to enable VOLTE call through Root or smth like that but I'm really a tech noob and I don't have a laptop.
Is there any way to fix this problem without needing a laptop? Or frankly, if anyone is willing to help me with this, I wouldn't mind paying you a small fee for your trouble.
I was going to resort to just selling off the phone but tbh I really like the phone and the UI, so I'd really want to fix it if possible.
Advice please! ):
