UPDATE JULY 4TH:
Several users confirmed the same issue since I first posted
Symptoms: USB-C Port not recognised, No charging/data connection. Recovery mode not possible due to no cable being detected
Tried: Swapping cables, charging plugs, tested safe mode, dev settings, toggled fast charging, reset settings, factory reset phone, swapped entire charging port to another official part (no change)
No moisture warnings (but happens for some people) Wireless charging unaffected
THIS ONLY OCCURED AFTER UPDATING TO ONE UI7, JUNE PATCH DID NOT RESOLVE THIS.
STILL NOT ACKNOWLEDGED AS AN ISSUE BY SAMSUNG
Original post follows
Tried cache clearing
Waiting for a new security patch
Dev settings changing usb behaviour
Wiping all settings
Factory reset phone.
Tried safe mode
Unable to charge or see a usb connection at all.
Its not a hardware issue, confirmed by installing a new charging port, this is software only.
