OnePlus One now shipping without Cyanogen branding
The removal of the Cyanogen logo shouldn't be seen as a sign that OnePlus is totally at war with Cyanogen - after all, the international One still ships with Cyanogen OS, and the companies have had issues only in India. Earlier this month, OnePlus mentioned that it had " altered the back covers of all OnePlus Ones to feature a cleaner and more unified look across all regions." Now we know what that meant.
Later this year, OnePlus will announce and launch a successor to the OnePlus One, possibly called OnePlus 2. We're anxious to find out if this will ship with Cyanogen OS by default or not.
