-For existing customers planning to migrate to the new Amplify Android v2, we recommend reviewing our [migration guide](https://github.com/aws-amplify/amplify-android/blob/main/documents/MobileSDK_To_AmplifyAndroid.md).
+# ⚠️ The AWS SDK for Android entered Maintenance Phase as of August 1, 2025.
 
-For new projects, we recommend using the latest v2 version of [AWS Amplify Library for Android](https://docs.amplify.aws/android/start/quickstart/) to quickly implement common app use cases like Authentication, Storage, Push Notifications and more.
+During this maintenance period:
+* Critical bug fixes and security patches will continue to be provided
+* No new features or enhancements will be added
+* Existing functionality will remain supported
 
-Note: v2 of Amplify Library for Android (currently GA) is built on top of [the AWS SDK for Kotlin](https://aws.amazon.com/sdk-for-kotlin/). You can access this underlying SDK via [the Escape Hatch from AWS Amplify](https://docs.amplify.aws/lib/project-setup/upgrade-guide/q/platform/android/#escape-hatches).
+We recommend that you start using [AWS Amplify for Android](https://github.com/aws-amplify/amplify-android), our modern feature-rich library designed specifically for building cloud-connected apps powered by AWS. You can refer to the [AWS SDK for Android migration guide](https://github.com/aws-amplify/amplify-android/blob/main/documents/MobileSDK_To_AmplifyAndroid.md) to help you transition to AWS Amplify for Android.
+This version is scheduled to reach End of Support on **August 1, 2026**. After this date, no further updates of any kind will be provided. See [maintenance policy](https://docs.amplify.aws/reference/maintenance-policy) for more information about the Amplify Client Library lifecycle.
 
-You can also use AWS Amplify with [your existing AWS cloud resources](https://docs.amplify.aws/android/start/connect-existing-aws-resources/). If you are unable to find features you are looking for in Amplify, please open an issue in [the Amplify Library for Android GitHub repo](https://github.com/aws-amplify/amplify-android/issues/new/choose) and we will be happy to consider you request.
