One UI 8 Issues

[Serpher]

After updating Galaxy S25+ to Android 16 with One UI 8 I've found these issues so fa

- charging sound is gone, flipping toggle for it doesn't do anything

- alarm that goes through the Sleep Mode is always displayed with little notification on the top of the screen instead of the full screen one; remaking it doesn't fix the problem; normal alarms work correctly

I hope this will get fixed.

Turn off modes and routines. Solves so much of the lagging

How do you roll back to 7?

After updating,  I no longer have any phone service. Can't do calls or text. Phone store doesn't know what to do. They gave me a new Sims card but it dis not fix anything. 

Now what do I do? I need a working phone.

Samsung S21 FE 5G automatically installed One UI 8 and I no longer have any service.  SIM card is not recognise.  Tried to reset network settings, airplane mode on/off, removed SIM but still no joy.   Can I roll back to One UI 7?

Between the 7 and 8 update Samsung has really fallen off. There's not one thing I like about it. It makes me not want to buy Samsung again. They should have made the new software on the new phones instead of updating it all on the old phones. I don't have time to learn a whole new system. Especially one that crashes all the time. When I go to buy a new phone I think I might try Motorola. It's got less power but at least it's not updated consistently with bad software. I wish LG was still in the game or Sony

With the 7 and 8 update, I've decided I'm going to try Motorola I know it's a less powerful phone but at least I won't have to put up with this nonsense. I wish LG was an option
