USB-C ports fail from three things: lint, wear and bent pins. The Flip4 is no exception, and because it rides in pockets and bags all day, lint is usually the first suspect and wear the second.
If a clean does not sort it, we replace the USB sub-board with an original Samsung part for the SM-F721. Fitting is included in the price shown, along with the part itself.

Common questions
What causes a charging port to fail on a phone this recent?
Mostly mechanical wear. The port endures hundreds of insertions a year, plus lint compacting at the bottom of the socket each time. Age matters less than use. We see worn ports on two year old phones and healthy ones on five year old phones.
Do you check anything else while the phone is open?
We test the phone before and after the repair, so charging and general operation get looked at as part of the job. If we spot anything else that needs attention, we tell you first. Nothing beyond the booked repair is done without your say so.
My Flip4 charges wirelessly but not by cable. Which repair is that?
That points squarely at the port or its sub-board, since wireless charging bypasses the socket completely. This is the right repair page. We confirm the diagnosis on the bench, and if it turns out to be something simpler, like debris in the socket, we tell you.

Working out what is wrong
A phone that will not charge is not always the port.
