Our andriod mobile phone most of time location is active, mostly apps need active our location on mobile. my question is that active location in our mobile phone or give permission to app to locate our location is scure for us or not? Dear Student ws, Usage of given location depends on the application. You should avoid giving location permissions to untrusted apps.
