Antwoord op "Camera App and Flashlight Not Working"https://www.techjunkie.com/how-to-fix-camera-failed-problem-on-huawei-p9/ “Restart the Huawei P9 (hold the “Power” button and the “Home” button at the same time for 7 seconds until the phone turns off and vibrates). Go to Settings, open the Application manager and then go to the Camera app. Select on Force stop, clear data and clear cache. Restart your phone again”. That worked for me. Good luck.
