I just downloaded the Norton Mobile App to my android phone & App Advisor flagged ES File Explorer as Medium Risk. When I tried to get details, the Norton app says: "No unusual behaviors found" and "no ads". Under Personal Data Shared it lists : Sim card details, installed app details & device details. Is this an actual risk (does shared mean transmitted to the app maker or some third party?) or is it something that any File Manager App would have to access just to function?
