4. Too Many Permissions
The good news is that Apple, Google and Microsoft have restrictions that force mobile application makers to request permission to access device resources, such as the camera and contacts. The bad news is that most users typically fail to read the fine print and almost always grant permission during the mobile app install process. Security experts say apps with too many permissions can be a concern for data leakage. Granting too many permissions could expose contacts, email addresses and device location data to unscrupulous people.
