Not one problem at all. All my apps work, my banking apps work fine and Samsung Pay works perfectly. I use Microsoft Launcher and it works great also. Other than a few new looks in various internal me us and things like that, I'd never know that I updated from Android 9 to 10.
Do a backup before install, 1st issue media but sent feedback and fix it. It took some time to load music and ringtones folder beside that is working ok.
