I'm disappointed to hear your not happy with your Samsung Flip⁴ phone @Seth007
Other owners have experienced delamination of the factory fitted screen protector on their Flip and Fold phone's.
It's a sheet of plastic that can sometimes peel away.
This happened on my Fold³ along the crease which I ended up carefully peeling off and using the phone without one.
Replacements are available via 3rd party accessories manufacturers or via asking a Samsung Service Centre to fit a replacement. I appreciate not everyone is local to a Samsung Service Centre or want to send their phone away to Samsung.
In some regions a Doorstep Repair Service is available via Samsung.
Software glitches can sometimes be remedied via clearing 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 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.
Or as a last resort a factory reset after a back up.
You can also let Samsung know of your issues via your Samsung Members App via the feedback section.
If I can be of any further help then please don't hesitate. Take care. 😎
