How to create multiple user profiles on Android

important things:
With Android’s support for multiple user profiles, you can share your Android device with other people without worrying about interference.
What is the purpose of Android user profile?
People who have already used a shared Windows system are familiar with creating an Android user profile. Each person has their own settings, programs and login.
Android devices have a similar feature for this purpose that many people might confuse with creating a user profile. This concept is more than adding a second Google account next to the main account; Rather, it has a completely different profile with apps, settings, background image, and the like. Like having two devices in one. When you add a new profile, you’re literally going through the entire process of setting up a new device.
However, the weakness that exists is the performance, as the number of users on the phone increases, its performance decreases. The more apps you install in each profile, the worse the performance will be. If you plan to set up a new profile for all family members on the tablet, keep this in mind.
