Check/Report any OnePlus Issues
Known as Bacon to Cyanogen, you can track known software issues with the OnePlus One on the Cyanogen site. If they’re not already aware of it, you can add the issue yourself. Before discussing ANY issue I would recommend searching this site first.

If you wish to root the OnePlus One (for instance, to install a different variation of OS) then the guide from the OnePlus One forums is a recommended read.
