Hello friends I am going to share something about the parallel space.This is basically used for multiple account like using dual whatsapp.So lets know about its merit amd demerits. Overally its a good app for using multiple account.You do not need to signout and again sign with a another account.There are two account simultaneously running on your phone. Its concept part is very good as it provides multiple account service for the android user.You need not to sign in again and again.Lets say you want to run two whats app on your phone.So generally what happened we need to sign out a existing whatsapp and login with your another whats app account.But by using this app you have to just sign in whatsapp in the phone and sign in with the parallel space with the another account.So in this way you will able to use multiple account at the same time. These are the cmon use of parallel space.I have not encounter any demerits yet.But it takes some time to run on your android.This is all about the parallel space.
