Mobium3456 Anyone have any ideas for troubleshooting?
If it's a brand-new device one possibility is a manufacturing defect. Though this would be very inconvenient, one thing to try would be flashing the device back to Google's OS. If the camera is still bad then, it will clearly be a hardware failure.
But maybe other people will have less-disruptive suggestions. For example, you could long-press on the Camera icon, pick App info, then wipe the cache and storage.
