So if these problems are proving to be a tough nut to crack, then your best course of action is to roll back to the earlier OS build. In this regard, if you have installed the One UI 4.0 via the Samsung Member’s App, then the downgrade is quite easy to carry out. All you need to do is remove yourself as a beta tester via that app and then perform the downgrade via the Smart Switch Desktop app. However, if you have performed the upgrade via the ADB Sideload or Apply Update from the SD Card method, then you wouldn’t be able to downgrade via the Member and Smart Switch App. Rather you will have to take the help of Odin. And in this guide, we will help you with just that. Given here are the detailed instruction steps to downgrade Samsung devices from One UI 4.0 to One UI 3.1 via Odin. Follow along.
