OnePlus One user and forum member “MiYzu” posted his major issue on the OnePlus online forums on August 25, and it was about his OnePlus One phone appearing to just smoke out and burn up without no external causes. We’ve seen a lot of phones do this, one recent “under-the-pillow” incident comes to mind, but this is a very real concern for OnePlus, especially as they begin to build on their early hype.
