My wife just changed my charging port and my battery on my iPhone 6 plus. When we open the camera app the phone goes to a black screen and then restarts. What could have happened to make this change? There were no problems before starting the repair.
Most likely what happened is the camera, back camera, got disconnected. That or the front camera for damaged. Check those two things. Should be the culprit iPhone 6 Plus Rear Camera iPhone 6 Plus Front Camera and Sensor Cable iPhone 6 Plus Front Facing Camera and Sensor Assembly Replacement iPhone 6 Plus Rear Facing Camera Replacement
