Hi @tinz80 and may I extend a Warm Welcome to the Samsung Community Forum 👋
As well as @Fiona26 excellent suggestion 👍 maybe also try 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 }
There js also a diagnostic test tool found in your Samsung Members App.

If necessary a Samsung Service Centre can assess your phone.
