The exact menu label varies by manufacturer, but the setting lives inside Developer Options. FlashGo must be installed before it can appear in the picker.
Open Developer Options
On many devices: Settings → System → Developer options. Samsung often places Developer options at the bottom of Settings. Xiaomi and other manufacturers may use “Additional settings.” Search Settings for “mock location” if the path differs.
Choose FlashGo
- Open “Select mock location app.”
- Choose FlashGo from the installed app list.
- Return to FlashGo and start a location or short route.
- Verify the result in an app you control.
If the option is missing
Confirm Developer Options is enabled and FlashGo is installed for the current profile. Managed work devices can restrict developer settings; do not bypass an organization policy—ask the administrator for a test device.
Common questions
Why is FlashGo not listed?
The app may not be installed in the active profile, or the settings screen may need to be reopened after installation.
Do I turn on USB debugging?
No. It is not required for the standard mock location app workflow.
