It seems that the One Plus 7 and OnePlus 7 Pro users need to wait for more time in order to get the stable release of Android 10 in their devices. The launch event of the OnePlus 7T series in London last Thursday clearly mentioned that the rollout of the official version of the Android 10 for OnePlus 7 series is still in process.
As per the latest updates from Global Product Operations Manager, Manu J., over the OnePlus forum, the company has currently begun a staged rollout of the Android 10 OTA update for the devices in order to avoid any mass-level report of critical bugs following the update.
The cautious approach taken by the Shenzhen-based OEM seems logical. In September, the company has released two back-to-back open beta updates of OxygenOS 10.0 for the OnePlus 7 series. Thereafter, OnePlus decided to halt the rollout of the stable version of OxygenOS 10.0 as the limited release of the version was littered with bugs.
As a result, the company is now rolling out the hotfix version of OxygenOS update for the OnePlus 7 series. Unlike a patch, a hotfix update is meant to fix some bugs but released on a limited number of devices. Hence, as the company has mentioned, users attempting to download the hotfix build with version number Oxygen OS 10.0.1 using VPN might fail as the rollout is not region-specific.
The changelog of the OxygenOS 10.0.1 update provided by Manu J. mentioned a number of under-the-hood modifications apart from the Android 10 upgrade.
It is to be noted that users who are running the previous version of OxygenOS 10.0 need to download an incremental OTA package of 113MB in size by navigating to settings > about phone > system update > check for OTA updates. However, regular users with Android 9 Pie would need to download a hefty 2GB sized update for the Oxygen OS 10.0.1 HotFix.
