"According to a patent filed at the European Union Intellectual Property Office, Oppo is likely to introduce an in-house chip, designated M1, in the coming quarters. Although there is no official confirmation yet, this signals a change in strategy with one of the top smartphone OEMs attempting to become more vertically integrated. However, this will demand a significant investment, especially in R&D and supply chain management. Xiaomi's similar attempt with the launch of Surge S1 met with different challenges that pushed out the launch of its successor, S2, by almost two years." – Tarun Pathak
