I think flyme should have dual app mode. It looks like miui. The dual app in the Normal mode uses two different accounts. The second space mode is the mode of using an additional google/flyme account and operates independently of other modes. It is not restricted and still install apk. It's not like guest mode on flyme. In other words, we can use an application with three different accounts on one device. second space and two in the normal mode using dual app. I think miui does this well.
