Notification Recorder is a free Android utility that allows you to retrieve deleted notifications and files. This tool can recover text messages and media attachments, including images, videos, voice memos, sound, animated gifs, and stickers. You can also view deleted images and messages in WhatsApp or any other selected application.

Notification Recorder listens to notifications from the selected applications and encrypts them to record on your device. When a media or message is deleted, it notifies you and attempts to save any attached media. It can recover various types of files, such as pictures, videos, animated gifs, sound, voice memos, documents, stickers, and more.

However, some issues may affect the correct operation of the app. If you mute any conversation, the app cannot record the notification. It is also impossible to recover notifications or messages that were deleted before installing the app. If messages are not being recorded, it may be due to the battery optimization setting. Additionally, automatic file download must be enabled to view deleted files.

Overall, Notification Recorder is a useful tool for recovering deleted messages and media attachments, but it may not work correctly in all situations.
