Removing demo mode from an Oppo device typically depends on the specific model and the level of demo lock applied. Retail demo mode is designed to showcase features and can often be restrictive, sometimes resetting the phone every few minutes Method 1: Standard Settings (Easiest)
Method 3: Third-Party Reset Tools (For Persistent Demo Modes)
You may have noticed that the demo mode app (often named DemoService or OPPOStoreMode) cannot be uninstalled normally. That’s because it’s a system app installed in the /system/priv-app partition. Even if you disable it via ADB commands (adb shell pm uninstall --user 0 com.oppo.demo), the phone will often re-enable it on reboot.
