  • •Android 18 restricts WRITE_CONTACTS permission to enhance security.
  • •Apps must use specific intents for contact modifications without permissions.
  • •New MANAGE_CONTACTS permission will be available for select apps in Android 17 QPR2.

Google's Android 18 update, released on October 28, 2026, restricts apps from using the WRITE_CONTACTS permission to edit contacts in the background. Instead, developers must utilize intents like ACTION_INSERT, ACTION_EDIT, and ACTION_INSERT_OR_EDIT, which do not require permissions. This change aims to mitigate risks of fraudulent apps manipulating contact data without user consent. A new permission, MANAGE_CONTACTS, will be introduced in Android 17 QPR2 for apps needing broader access. The update is part of Google's ongoing efforts to enhance user privacy and security. Developers are advised to review the new guidelines and migration steps provided by Google. The final version of Android 18 is expected to be released in June 2027.
