There would be one more thing you can look at and that is the connector on the logic board. Check there is no damage to the pins; you might need a magnifying glass to check properly.

Other than that it will cost you money as the next step would require a reputable repairer to check the diode readings of the connector to see if there are any open or shorted lines plus check to see if it is getting power. This is not easy as you need the connectors connected and the camera app open.

If such is the case I would recommend this:

If you launch the camera app [SPAM deleted], and see a black screen that doesn’t change, try the following:

  1. First, make sure that nothing is actually blocking the camera lens. You may have put a case on incorrectly, or there may be something stuck to the camera hole.
  2. Close the camera app by double-clicking the home button and swiping the app card up to kill it. On an iPhone X, swipe up from the bottom and leave your finger halfway up to bring up the app switcher, then long-press on any app preview until a red circle shows up in the top left corner. Close apps by tapping on that circle or just swipe the card up and away.
  3. Try launching the camera app again.
  4. If that didn’t work, try restarting your device and then launching the camera again.
  5. Try switching back and forth between the front and rear-facing cameras to see if the black screen appears on both. If it’s only one, you may need to take it to an Apple Store.

If you’ve tried everything above and it didn’t fix your camera problems, then you may have a hardware problem. You should try the following:

  1. Double-check that the camera lens is not obstructed by a case, sticker, or similar objects.
  2. Make sure there are no smudges, dirt, or debris on the camera lens. Smudges and fingerprints should wipe away easily with a microfiber cloth. If dirt and debris are under the glass lens, take it to an Apple Store or Authorized Service Provider.

I hope this helps!

Regards.

thank you for your answer. but i did all those steps before i replaced the frontcamera 3 times. the only step i didnt do is bring it to the apple store. an independant repairer tried and failed tho.

its not worth it to pay more than a 100 euro's to fix the phone, i would like to fix it myself but i cant find the solution.

Assuming you've exhausted all of the possible software options up to and including a complete DFU mode restore of the phone, then the next logical step is to replace the camera.

iPhone 7 Front Camera and Sensor Cable Replacement

If you've done that and it's still not working, then you're in the same situation as the original poster where you'll need to check the logic board connector followed by board level debugging.
