How to downgrade onePlus 8 from Android 12 to Android 11

Recently, OnePlus released the Android 12 update for the OnePlus 8 series and the OnePlus 8t. However, there are a lot of people who are complaining about different kinds of bugs and crashes with their devices. Many people are also facing app crashes and compatibility issues. So, if you are also facing any of the issues, then you can surely downgrade your OnePlus 8 device to Android 11 through this tutorial.

The new update brings a lot of new features to the phones, but along with that it also brings some new bugs. Which is a bit frustrating. This could be because of the new Color OS and Oxygen OS merger. In a recent report, we are being told that OnePlus is now not merging into Color OS, but they were halfway there, so it will take time to revert back to oxygen OS. The other reason for bugs is that the OEM did not do proper testing with the open and closed beta, as, after just a couple of beta releases, the company pushed the stable update for everyone.

Some people had connectivity issues like no VOLTE and no 5G access, while others had an ambient display and poor battery issues. You can fix all of this by downgrading back to Android 11 on your OnePlus 8 series device. Don’t worry we have got you covered, this method won’t wipe your data, and then downgrade to Android 11 will retain all of your personal data and apps as it is if you take a backup beforehand using the OnePlus Switch App. However, some of the apps might need to be reinstalled due to compatibility issues, but other than that there shouldn’t be an issue.

Recently, OnePlus has been a lot messy in terms of providing updates, they are either late or not at all providing any updates to their smartphones and if they are providing, they are coming full of bugs and crashes. So, in that case, a rollback to the older version of the software is always a good option to try. Until the next stable software update is pushed from OnePlus which doesn’t have any major bugs, then you can try and update your phone once again.
