May I ask why you Deregistered? I have the software update for ONE UI BETA 4 PROGRAM in my Software Updates, but am looking for more info. Be for I download and install or choose not to.
Some of the apps that don't work on beta are usually those that require secure platform (in a Google certified environment) like banks, wallets, secure folder. There are other bugs that come with testing beta firmware which is why it's advisable not to install it on your daily driver. Do a full backup before installing and ensure everything in your secure folder (if you use it) is moved out before you install it. You can always get out of the beta and reinstall 11/restore from backup.
Yes indeed, although I am tempted and received the One UI Beta banner running S21 Ultra (SM-G998U1), and after thoroughly reviewing a lot of threads, I will (patiently) wait for the final General release 😀 😉. However I'm quite excited about the progress and ' due diligence ' on the part of the Samsung One UI Developer Team to implement features suggested by Samsung Members!
