Nothing seems to come easy for OnePlus. There have been software issues and hardware issues with the One. However, the biggest problem is its availability. The invite system was a total mess as no one could get a hold of an invite. And there was really no reason for it. So OnePlus scrapped it in favor of a pre-order system. The company would allow prospective buyers to purchase the device at select times. Unfortunately, the pre-order system is not all that much better. The servers used experienced issues trying to handle a large influx of people.
