OnePlus (Chinese一加科技pinyinYījiā Kējì) is a Shenzhen-based Chinese smartphone manufacturer founded by Pete Lau (CEO) and Carl Pei in December 2013. The company officially serves 34 countries and regions around the world as of July 2018. They have released numerous phones, amongst other products.
History
OnePlus was founded on 16 December 2013 by former Oppo vice-president Pete Lau and Carl Pei.According to the Chinese government's documentation, the only institutional stockholder in OnePlus is Oppo Electronics. Lau denied that OnePlus was a wholly-owned subsidiary of Oppo and stated that Oppo Electronics and not Oppo Mobile (the phone manufacturer) is a major investor of OnePlus and that they are "in talks with other investors" (although nothing has been announced to date but it is clear that oneplus and oppo mobile(not electronics) are siblings and they do not share parent child relationship.). The company's main goal was to design a smartphone that would balance high-end quality with a lower price than other phones in its class, believing that users would "Never Settle" for the lower-quality devices produced by other companies. Lau explained that "we will never be different just for the sake of being different. Everything done has to improve the actual user experience in day-to-day use."He also showed aspirations of being the "Muji of the tech industry", emphasizing its focus on high-quality products with simplistic, user-friendly designs. Continuing Lau's association with the platform from the Oppo N1, OnePlus entered into an exclusive licensing agreement with Cyanogen Inc. to base its products' Android distribution upon a variant of the popular custom ROM CyanogenMod and use its trademarks outside of China.
The company unveiled its first device, the OnePlus One, on 23 April 2014. In December 2014, alongside the release of the OnePlus One in India exclusively through Amazon, OnePlus also announced plans to establish a presence in the country, with plans to open 25 official walk-in service centres across India.
In April 2014, OnePlus hired Han Han as the product ambassador in mainland China.
On 9 March 2014, the company expanded its operations to the European Union. As of July 2018, OnePlus serves to the following 34 countries and regions: Australia, Austria, Belgium, Bulgaria, Canada, China, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hong Kong, Hungary, India, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Poland, Portugal, Romania, Spain, Slovakia, Slovenia, Sweden, United Kingdom, and United States.

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.
