Confirm the hardware is disconnected
Nothing should remain connected through the HHJ Pro device. Temporarily disconnect a charging cable as well.
HHJ PRO / RESTORE LOCATION
The real location usually returns after the hardware is removed. If it does not, follow these four steps.
Disconnect HHJ Pro, fully close the relevant apps, then open Settings → Privacy & Security → Location Services. Turn Location Services off and on again. Restart the iPhone if the location is still incorrect.
Follow them in order. You normally do not need to reinstall the app or reset the iPhone.
Remove the hardware from the bottom of the iPhone.
Fully close HHJ Pro and the app you were testing from the app switcher.
Open Settings → Privacy & Security → Location Services. Turn it off, then on again.
Reopen Maps. Restart the iPhone once if the real location has not returned.
Start with the simple checks. Do not immediately delete apps or reset the iPhone.
Nothing should remain connected through the HHJ Pro device. Temporarily disconnect a charging cable as well.
Open the app switcher and swipe away Maps, HHJ Pro, and the target app before reopening them.
If refreshing Location Services did not update the position, restart the iPhone once.
The target app may still hold its previous location state. Fully close HHJ Pro and the target app, refresh Location Services, then check again.
Check the system Maps app first. If Maps is also incorrect, restart the iPhone. If only one app is incorrect, that app may not have refreshed.
Usually not. Complete the four steps first, then contact support if the issue remains.
