Notification History Log is an app that lets you keep a complete record of all the notifications in your Android smartphone. So, if you accidentally delete a notification, you can always get it back.
Once you’ve activated Notification History Log, all the notifications that you receive will be saved in the log. Also, you can take a look to the advanced notification view where you can check any of your notifications in detail: name of the app, exact time of the notification, title and description of the notification.
Inside the configuration settings, you can establish the maximum size of the notification log or temporarily disable it. You can also choose whether you want to directly access the advanced notification view when you enter the app.
Notification History Log is one of those apps that you’ve wished you had when you accidentally delete an important notification. The best part is that it only takes up 2MB.
