@annerc0re you don't necessarily need a computer to enter the required mode to clear the phone's System Partition Cache Files Section.
Sometimes inserting your earphones or hooking upto a Tv's USB Port will work.
This explains > 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 }
Also try your sim card in the ²nd sum card slot if relevant to your phone model.
Your phone has a diagnostic tool found in your Samsung Members App.
Also as a process of elimation can you try your sim card in another phone.
If i can be of any further help please don't hesitate to ask 😎
