SM-G930U, front camera replaced, now getting "Camera Failed"

Work in a repair shop.

I misplaced a customer’s front camera module while doing a screen repair. I grabbed one we had for replacements - it had G930F inscribed on it. Upon launching the camera app, it says “Camera Failed” and force closed the app. The customer’s device is an Galaxy S7, model SM-G930U. I know the rear camera modules vary with each model, but I’m not sure about the front ones. The customer said this did not happen before the repair.

Smart stay is off. I tried another part, same G930F inscription. Using the stock Samsung camera app.

Anyone help would be appreciated!
