I really only clear my system cache partition files after a major software update.
I've had my phone from launch date and it's worked exemplary.
Have you tried Safe Mode > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict.
Samsung need user experience feedback so they can look into real world user issues so I'd urge anyone experiencing issues to send feedback and any applicable error reports via their Samsung Members App.
I'm sorry to hear of your user experiences and hope they improve for you as this phone in my opinion is a true workhorse.
I wish you all the best.

The advice I offer is my own and does not represent Samsung’s position.
