Why does the Maps application keep launching? For some strange reason Google Maps launches on its own.  It doesn't launch all the way though.  It just leaves a black screen.

Does anyone know why this is happening?
Try Uninstalling and re-installing it. 
Clear the app data. 
Might be a bug with the custom ROM (ignore if on stock).


As for WHY it is happening, could be a faulty installation IMO, but if the package was faulty, it wouldn't get installed in the first place. Anyhow, just try the above steps.
