Hello and may I extend a personal Warm Welcome to the Samsung Community Forum 👋
I'm sorry to learn of the issues your currently experiencing with your phone.
Try a forced reboot by holding down the volume down key and power button simultaneously for more than 7 seconds to restart it. When your phone resets, you will feel it vibrate.
If a phone is displaying issues after an update then the generic troubleshooting step is to Clear the Phone's System Partition Cache Files Section.
- Clear Cache Files from the phone's System Partition Section > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's }
You could also consider > Settings >;General Management > Reset > Reset All Settings.
A very last resort is to back up and factory reset.
If i can be of any further help please don't hesitate to ask 😎
