Get RAS : Recent App Switcher old version APK for Android
Nougat update feature can be used in Kitkat,Lollipop,Marshmallow with this app.
We all know about one of the update feature in Nougat is the recent app switcher. By double tapping the recent apps menu button the last app we were using is pushed to front. The earlier versions of Nougat doesn't have this feature. So this application will fulfill that feature in other versions too. I have checked in Kitkat(Asus zenfone), Lollipop(emulator) and Marshmallow(Redmi 3s prime).
