If it doesn't work for some of you guys, try installing different magisk, search on chrome and type magisk download, and choose v26-1 and if your phone is not root, download vphonegaga gold mod vip, then try it, it work fine for me, the problem is the magisk! The one from here doesn't work on me, so i search and download the magisk v26-1 from chrome, and watch YouTube for the tutorial on how to install zygisk from vphonegaga. Hope it works for you as well guys.
