OnePlus CEO made the following commitments this morning:

Hello everyone, today 315, I decided to announce a decision that may win the industry: #OnePlus 9# series models, will enjoy 2 years of official warranty service! Twice as long as the industry's official warranty!
I think that as the flagship machine emperor, the OnePlus 9 series must not only lead the industry in terms of products, but also do the best in terms of service. Seeing the survey data, the replacement cycle of flagship machine users is about 2 years, so this is equivalent to you buying our new products, and almost the entire life cycle can enjoy the official warranty.
I know that this decision will be like two years ago we focused on the screen, to raise the requirements of users in the whole industry for flagship services; colleagues in the marketing department also reminded me that this decision is easy to hate, will make it difficult for friends to do, and even hack us, saying that OnePlus has added costs to pricing and so on. I told them that if everything is forward-looking, then nothing can be done well, we are going to buy the best service guarantee for the users of the OnePlus 9 series! Things that can bring real benefits to users are welcome to follow up.
