The Android system has always been known for its freedom and openness, but it is also because of its openness that its ecological application is getting worse. So Google started to strengthen the user's control over mobile phone rights from Android 6.0. To obtain sensitive permissions such as mobile phone calls, text messages, and location, you must do so with the user's authorization rights.
After Facebook’s privacy of users this year, Google has placed more emphasis on the privacy of Android. So, the Google Play Store announced new developer terms today. In the new terms, Google said it can get users’ calls, text messages, etc. Information, must be the system default program, third-party App is not allowed to retrieve.
That is to say, after the Android user downloads the third-party SMS software, if it is not set as the default program, even if the app is given permission during the installation, it can not get the content information such as SMS, phone, etc. It also brings drawbacks, because for users, third-party apps that can automatically identify and fill SMS verification codes will no longer be able to provide this feature.
