Spoofing stops in the background, another app shows your real location, the marker is stuck or jumped away, the screen ignores touches — common situations and what to do about each.
Most often a suitable app is simply not installed: the system builds the list and shows only apps that can act as a test location source. Install the app and return to settings.
Full answerMIUI and HyperOS (Xiaomi, Redmi, POCO) kill background apps more aggressively than others. Turn on autostart for Mock Location and remove battery restrictions — the app suggests this on first launch.
