New updates are being added to the bottom of the story…
Original story (from November 9) follows:
It is the season of new Android OS updates and as expected, OnePlus is one of the most featured names at this point in time.
Google was the first to dish out stable Android 11 updates followed by you guessed who – OnePlus! The Chinese vendor has already updated both OnePlus 8 and OnePlus 8 Pro to OxygenOS 11.
Next in line is reportedly the OnePlus Nord before the OnePlus 7 series joins the party somewhere in December. Indeed, the company still has plenty of OxygenOS 11 development to do.
This development will not only involve migrating more devices to OxygenOS 11 for the first time, but also maintaining optimum performance of those already on the updated firmware.
This is where the latest OnePlus 8 and OnePlus 8 Pro developments come in. The duo recently bagged an update to OxygenOS 11.0.1.1, tagging along October security patch, Canvas mode with no AOD integration, and more.
But according to multiple user reports, this update came with an unwanted guest. Apparently, those who switched to OxygenOS 11.0.1.1 are no longer able to use VoLTE and VoWiFi functions on their OnePlus 8 and 8 Pro sets.
Looking at the screenshot below shared by an affected OnePlus 8 Pro user, there is still no VoLTE or VoWiFi despite enabling the functions in the settings menu. It also seems like 5G is affected in some cases.
At this point, it seems pretty obvious who the culprit is. In fact, this could partly be the reason OnePlus has already halted the rollout of OxygenOS 11.0.1.1 update.
In a small note added to the announcement post, a staff member points out that the rollout has been halted as the company continues to look into user reports, but there are no specifics.
Another reason for halting the rollout could be related to the mix-up that led to open beta testers receiving an OTA update that switched them to the stable channel.
If you happened to have received the OxygenOS 11.0.1.1 stable update over Open Beta 3, follow the steps below to avoid data loss:
Regardless of the reason, OnePlus halting the rollout of this buggy firmware should help reduce the number of affected OnePlus 8 and 8 Pro users. We will follow up and let you know when the bug-fixing OTA arrives.
