I got a new iPhone 7 running 10.0.2 and I've noticed that now and then when I open the camera app the screen is very dark. If I power off and on (not hard reset), the camera works normally again. I'm not sure if this is a hardware defect/bug or an iOS 10 bug? Anyone else experience this? UPDATE: iPhone 7 running iOS 10.1.1 I have followed all the troubleshooting steps that Apple has instructed me to and this issue still persists! The issue is as follows when you open the camera app: - the screen is black/almost black/blurry - switching between the front and back facing cameras makes no difference - the yellow square (auto-focus) flickers rapidly and sometimes pulses slowly - the issue happens in an unpredictable way. You can't make it happen on demand. - you cannot take a photo when the issue presents itself Very temporary solution: - Switch to "video" and back to "photo" mode - Sometimes powering on/off can help - Sometimes force restarting can help Troubleshooting steps you've done: - On iPhone: "Reset All Settings" - On iPhone: "Erase All Content and Settings" - On iTunes: Restore iPhone and setup as new - On iTunes: Restore iPhone (Recovery mode) and setup as new - Do not restore from an iCloud or iTunes backup! IF you have completed the troubleshooting steps outlined above AND you have the camera issue as I've described above CONTACT APPLE SUPPORT AND GET THEM TO ESCALATE THIS TO THE ENGINEERING TEAM!
