You cannot delete the OPPO Wallet, the Health app, or the proprietary Music player.
There is a shadow version of OPPO living inside the Great Firewall: It is faster, angrier, and packed with AI features that the rest of the world won’t see for another year. And despite the risks, a growing subculture of Western users is desperate to get their hands on it.
