Well I recently updated to one ui 4.1 and I cannot use the home or back button. It was working perfectly fine before the update.

Same here. Home button and back button not working after the update. Also my phone is being laggy. Will talk to tech support tomorrow. S21 Ultra annoying. Lol

I thought it was just me . My button works but it doesn't go home. It just doesn't do anything if I long hold I can set it to settings and Google but it doesn't take me back home

So what seems to have 'fixed' this: I went into Settings-->Apps-->Choose Default Apps and set the home app to Nova7 (or OneUI, whatever you use). I thought it was strange that Mobile Services Manager was showing, so I wanted to disable it, but was unable to. What I did do was go to Settings-->Apps-->Mobile Services Manager and hit Force Stop, and then went into Storage and Clear Data. I then went back to Settings-->Apps-->Mobile Services Manager and removed the permission to access the Phone.

^ mine didn't work with that, I cleared the data and cache for one ui and mobile manager services.

Thank you so much! This worked for my wife's phone! The only thing I did different was I turned the phone permissions back on to the mobile services manager. But the home and back buttons are working fine now!
