The Nokia 7 Plus is one of the few devices that Google released a beta version of Android P for. However, a recent update rolling out to those on the beta version is forcing them back to Android 8.1 Oreo.
The 1.3GB update is said to bring June 2018’s security patch but also has a full version of Android Oreo bundled with it. It also causes devices to crash or freeze, and apps to force close. Affected users say the rollback option on the Android P page doesn’t work since it is older than the current build. Some users can’t even boot past the Nokia screen.
The fix, therefore, is to do a complete factory reset via the recovery menu which then pushes them back to Android Oreo and causes them to lose their files. Nokia seems to be aware of the issue already but a fix has not been provided yet.
There seems to be something terribly wrong at Nokia with respect to updates. Just last week, Nokia 6.1 users had to deal with Wi-Fi issues after receiving May’s security patch.
