Owned the OnePlus One now for about 2 months maybe closer to 3 months.

Hardware wise I can’t fault the phone hardware pretty much everything works how it should do.  Quality of the front camera is nothing compared to the back but does the job.  Battery is decent just need to keep an eye on the apps.  Screen is great in range of settings. Operating system wise the phone runs on Android Cyanogenmod. Cyanogenmod clean version of android pretty much limited with what software is default on the phone.  Have to say enjoying pure version of android.  Platform does have some major scope on what it can do when it is not limited by business deals.

Overall I like the OnePlus One as a phone and safe to say that next phone likely to be another OnePlus..
