Quite a few are saying the same.
For myself, I had issues in my S23U. I joined beta at stage 3 and followed the beta to the end then stable. Internet, browsing and apps all slow, painfully slow. A Wipe Partition Cache fixed that.
Emojis don't concern me, they are what they are.
Text font I 10000% agree with you. Poor options.
I said from the day I got beta 3 that the changes are negligible and not worth stressing over / waiting for and many shot me down for that view but now....... So many complaining.
Overall, a poor Android update made worse for many by Samsung UI over the top.
I am not employed by Samsung nor do I receive any remuneration as a Samsung Members Star.
My device is an S25 Ultra.
