ichanmrg , via OnePlus Nord , May 8, 2021 : Okay, so I searched so many forum threads and I searched Google but I seem cannot find the official reason from OnePlus for the issue: Why does 5G, VoLTE, and VoWiFi suddenly disappeared on OnePlus devices? I find it strange that the said features suddenly removed on latest updates. I opted in to beta releases of OOS with the hope that these features will come back, but to no avail. What is happening to OnePlus and its software updates? Here in the Philippines, we have a new network called DITO where 2G is not implemented and requires VoLTE to place calls. I would like to use it on my OnePlus Nord, so I was force to is PDC. Unfortunately, every changing of SIMs leads to the reset of the config, making VoLTE unavailable until I do the PDC trick again. It is kinda sucks and a bit ridiculous that some other brands (like Samsung) have these features right out of the box. Heck, they even proved that they can even provide better software updates in a timely manner. That is a miracle, I should say. I need enlightenment with what is happening.
