One UI 2.0 beta program based on Android 10 is now live in India, France and Poland. Owners of the Galaxy S10e, Galaxy S10, and Galaxy S10 Plus can join the program with the Samsung Members app.
Once enrolled in the One UI 2.0 beta program, the update can be downloaded from the Software update menu in Settings by pressing the Download and install button. The update size is around 2 GB.
Reports suggest that the beta program will soon be coming out in Spain, France, the UK, Poland, and China as well.
If you update to the beta, we suggest you to backup your data before doing updating, because a downgrade to Android Pie would require a reset of your device and all the data would get lost.
