Hi @TTrree and may I extend a Warm Welcome to the Samsung Community Forum.
There is a diagnostic test tool found in your Samsung Members App to see if that helps especially.
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 }

You can Ask a question via your Samsung Members App too.
A Samsung Service Centre can help > https://www.samsung.com/uk/support/repair/
Daily Driver > Samsung Galaxy s²⁵ Ultra 512Gb ~ Titanium Black.
The advice I offer is my own and does not represent Samsung’s position.
I'm here to help. " This is the way. "
