DOWNLOAD Xposed Framework Installer apk
The Xposed Framework Installer is the must-have app for rooted Android phones. It gives apps — or modules, as they’re called — the ability to make system-level changes to your device, of the kind you would have previously needed to flash a custom ROM to achieve.
Installing Xposed on Android 4.4 (or lower) devices is as simple as installing an APK file; on 5.0 Lollipop and higher it requires an extra step
Xposed Modules customize, tweak, and enhance your phone in pretty much every way imaginable. Some of the best Xposed Modules, including the permissions manager XPrivacy, can be downloaded through the Play Store. Others, such as the awesome GravityBox, need to be installed separately..
In order to install the downloaded APK file, make sure you allow Third-party Applications to be installed in your device or else downloaded APK file will not be installed. To allow just go to Settings, Security and check the Unknown Sources/Non-Market apps.
