I think the part that bothers me the most is that, the customer is likely completely oblivious to the fact that a repair person used a third party part in their device.

I don't think most cellphone users are discerning enough to start checking if the repair place is actually licensed by Samsung to perform repairs or not. They just see the Samsung logo under the banner of "we fix these brands" and go in. As long as it's fully working when they walk out, they couldn't possibly give fewer shits whether genuine Samsung parts were used to fix the device.

This is essentially victim blaming. Anyone who can fix the phone themselves with non-Samsung parts is going to do it themselves and never get "caught" doing it. So instead of "catching" the "bad actors" putting non Samsung parts into phones, they're putting that responsibility on customers? That's a PR nightmare. What the fuck are they thinking?
