The invite system, and its discontinuation
Early phones were only available through a system whereby customers had to sign up for an invite to purchase the phone at irregular intervals. The system was claimed to be necessary for the young company to manage huge demand. OnePlus ended the invite system with the launch of OnePlus 3 on 14 June 2016. Announced via an interactive VR launch event, the OnePlus 3 initially went on sale within the VR app itself. OnePlus touted the event as the world's first VR shopping experience.The phone was made available for sale later that day in China, North America and the European Union on the OnePlus website, and in India on Amazon India.
"Smash the Past" campaign
On 25 April 2014, OnePlus began its "Smash the Past" campaign. The promotion asked selected participants to destroy their phones on video in an effort to purchase the OnePlus One for $1 (US). Due to confusion, several videos were published by unselected users misinterpreting the promotion and destroying their phones before the promotion start date.
The campaign was heavily criticized for environmental waste and safety concerns, due to batteries and phone components posing potential hazards to participants destroying their phones. OnePlus allowed the winners to donate the old phone. There were 140,000 entrants in the contest with 100 winners.
Warranty rejections
OnePlus One issue with yellow display band at the bottom of the screen which affected some units were not covered under warranty. A similar issue was reported for Oppo Find 7 and Oppo Find 7a and Oppo covered it under warranty.
