sonny.haze , via OnePlus 7 Pro , May 31, 2020 : NO ROOT REQUIRED If you're not familiar with Parallel Apps you should really take the time to check it out. it can be found under settings>utilities>Parallel Apps. The way it's setup gives you the ability to basically clone an app. However, the apps that are eligible in this menu are quite limited. But it doesn't have to be. You can turn ANY app into a Parallel App. Because in truth OnePlus as created a hidden account. Number 999. open adb fastboot window on your computer. hook up your phone. run this command: adb install --user 999 (app_name.apk) note that these apps you install manually will not show up under the parallel apps utility menu. but who really cares. they'll be on your screen or in the app drawer.
