Turn On/Off USB Debugging auf Realme
USB debugging gives developer tools like ADB, Android Studio or Scrcpy direct access to your Realme phone over a USB connection. Without it, your computer can charge the phone or transfer files, but it cannot run commands, install APKs via ADB or mirror the screen.
On Realme UI, this switch sits inside the Developer options menu, which stays hidden until you unlock it manually. That is a deliberate safeguard, since USB debugging grants deep system access and should only be active while you actually need it.
Where to find the switch
Once Developer options are unlocked, go to Tap on Settings ➔ Tap on Additional settings ➔ Tap on Developer options ➔ Enable or disable USB debugging ➔ Tap on OK. Confirming with OK is required, otherwise the toggle reverts itself.
If Developer options do not appear in Additional settings yet, you first need to unlock them by tapping the build number multiple times in the About phone section. Only after that step will the Developer options entry, and with it the USB debugging switch, become visible.
When to turn it off again
Leave USB debugging disabled for everyday use. Turn it on only right before connecting to a PC for flashing, debugging an app or using ADB commands, then switch it back off once the session ends.
