SAMSUNG Galaxy S21 Ultra G998U 5... vs Flip Phone 4G LTE Volte Unlocked...

This defective brick constantly says sd card unmounted when using. After reaching out to try and return the phone, the description claims the phone is fully unlocked. That's a lie. Then blamed me for returning a fake phone.

This is a 4g phone, as advertised. The incoming call ring is week. She likes the phone fine just wishes the ring was louder.
