How to get Android P features on any Android phone
If your phone is not compliant with the developer preview of Android P, there is still a way you can experience the several new features of Google's latest operating system. Developers have made separate apps that replicate Android P's different features. These can be installed on any Android device, and provide users running older operating systems with the Android P experience.

Edit screenshots natively
Android P allows users to edit screenshots natively right after taking them without having to rely on third-party apps for the same. You can also take screenshots via the Google Assistant on Android P. To get this functionality, download the Markup app. You'll first have to share your screenshots with the app, which will then allow you to directly make alterations to it.
Prevent users from unlocking the phone via biometrics
Android P users can disable unlocking the phone via the fingerprint sensor by tapping the power button and clicking on "Lockdown." Download the Lockdown APK to enable the feature. Users can also download the Android P launcher APK to change the launcher of their smartphone.
