WAMR is a utility app that allows users to recover deleted text messages and media attachments such as pictures, videos, voice notes, audio, animated gifs, and stickers. The app works by reading notifications received on the device and creating a message backup based on the notification history. When a message is deleted, WAMR immediately shows a notification and attempts to save any media attached to the message. However, there are limitations to the app's functionality, such as the inability to recover messages that were silenced or being viewed before deletion, and the inability to save files that were not completely downloaded.

To use WAMR, users must download the app and grant it access to notifications. The app will then create a backup of all notifications received on the device, allowing users to recover deleted messages and media attachments. However, users should be aware that this is a workaround and may encounter limitations caused by the selected messaging app or the Android operating system.

WAMR can recover various types of media attachments, including pictures, videos, animated gifs, audio, voice notes, documents, and stickers. However, the app may not be able to save files that were not completely downloaded or if the sender deletes the message before the messaging app downloads it. Additionally, some media may not be automatically downloaded if the user is not using a WiFi connection, which can be changed in the messaging app settings. Users experiencing issues with the app can contact the developer for assistance.
