I updated my nexus 5 to 6.0 and now the camera won't work. Factory wipe did nothing, but a wipe that happens when unlocking the boot loader did let it work for less than a day. Now I can't get it to respond at all, it just thinks that the camera doesn't exist. Anyone know of how to perform hardware tests to confirm and what to look for next? I can't find and camera daemons running via 6.0
