Here are the instructions on installing the Android 10 Q and One UI 2.0 Beta software on your Samsung Galaxy S10. I also go through the steps required to downgrade back to Android 9 Pie at the end of the video. Full instructions are below.
Please make sure you back up your phone!! Don't ever upgrade to a Beta firmware without backing up your important stuff! The same is said for downgrading - back up first!
To downgrade back to Android 9 Pie you must withdraw from the Samsung Members Beta Programme:
Load Samsung Members
Click Settings in the top right
Click One UI Beta Programme
Press Withdraw at the bottom of your screen
You are now withdrawn from the programme.
To downgrade back to Android 9 Pie you must wait for the next Android 10 Beta update to be released. This has been confirmed by Samsung as you will see at the end of the video.
When the next update is out, connect your phone to the PC and run Samsung Smart Switch.
You should then see a "Downgrade" button appear and you'll then be able to downgrade back to Android 9 Pie.
