One of the many reasons users choose not to root their Android device is the fact that it disables pay services like Android Pay. Not to long ago a systemless root was released which allowed you to use Android Pay as long as you first disabled Xposed Framework and rebooted your device. That is alot of trouble when you are standing at a register and need to pay for your goods.
There is now a much quicker way to use Android Pay while rooted with Xposed Framework installed. Magisk is the new universal systemless interface. For this to work you will need Magisk installed and you will need the Magisk compatible version of SuperUser. You will also need the Magisk compatible Xposed. Open Magisk Manager and simply click unmount root.io. Now Android Pay will work. The option temporarily fully unroots your phone until you toggle root back on.
