Long-press on an empty section of your home screen and press Widgets. Next, scroll to Settings and drag its icon anywhere on your home screen. Once you place it, you’ll be greeted with a menu asking what you’d like this shortcut to point to.
Scroll down to Notification Log and you’ll now have a shortcut on your home screen that takes you directly to a history of notifications. Current notifications are shown in white, while past ones are light gray. You can tap any one to jump to its app info page.
If you don’t see this setting under your widgets, install an app like Notification Saver on any device running Android 4.4 or above. This app performs a similar functionality to the stock method, but also allows you to export the notification log if you desire.
One thing I love about Android v iOS is the persistence of lock screen notifications even after unlocking … Missed so many on iOS.
