Medium Application Data can be Backed up[android:allowBackup] flag is missing.
The flag [android:allowBackup] should be set to false. By default it is set to true and allows anyone to backup your application data via adb. It allows users who have enabled USB debugging to copy application data off of the device.
High Service (.EasyOneHandService) is Protected by a permission, but the protection level of the permission should be checked.
Permission: android.permission.WRITE_SECURE_SETTINGS [android:exported=true]
A Service is found to be shared with other apps on the device therefore leaving it accessible to any other application on the device. It is protected by a permission which is not defined in the analysed application. As a result, the protection level of the permission should be checked where it is defined. If it is set to normal or dangerous, a malicious application can request and obtain the permission and interact with the component. If it is set to signature, only applications signed with the same certificate can obtain the permission.
