Samsung wasn’t really known to be the OEM that rolled out faster Android updates. However, as of late, things are changing and for good. The early signs were already evident in the rollout of OneUI 2.0 and with its third iteration, the OEM further concreted the evidence of faster updates. The S20s and the Note20s have already received the latest OneUI 3.0 Android 11 updates. Likewise, many other Samsung devices are in the Beta or testing phases and should be blessed with the said update sooner than later.
However, the latest build of any software isn’t really polished and has a few rough edges. And if you are on a beta build, all these things are pretty much evident by themselves. As a result, the user experience might turn out to be quite buggy, which infact is the last thing that one would want. In this regard, waiting for a stable update is one option, but that isn’t the feasible or viable one for many.
This is because the stable update might take some time in reaching your device. So what else could be done? Well, the best bet is then to downgrade any Samsung device from Android 11 to Android 10, i.e from OneUI 3.0 to OneUI 2.0 or 2.5. And in this guide, we will help you do just that. Follow along for the instructions.
