OnePlus gave some of its customers the first access to the Android 11 beta in June. At that time, the company released the system for OnePlus 8 and OnePlus 8 Pro phones to the public. After several months of testing and finding bugs in the software, the first fully stable version of OxygenOS 11 was developed and it's possible to download it.
OxygenOS in 11 version is available only for the previously mentioned two OnePlus' phones. The update requires at least 3GB of free internal memory in the phone and a battery charge of at least 30%. In the future, OxygenOS 11 will also be released for OnePlus 7T Pro, OnePlus 7T, OnePlus 7 Pro, OnePlus 7, OnePlus 6T, OnePlus 6 and OnePlus Nord phones.
