There was a time when it was practically expected to discover that someone owned two phones. On that level, the necessity to keep personal and professional life distinct still persists in this age of dual SIM phones, especially since mobile apps don't always support managing multiple accounts.
Different manufacturers have used various and inconsistent approaches. Still, it appears that Google is creating the framework for several copies of some programs to be installed on the same Android user profile.
Sometimes you want to use the same software or service for several accounts or use cases. Some apps, such as Twitter, Gmail, and Telegram, allow you to log in and move between multiple accounts. Most, however, do not, and users are sometimes forced to seek solutions, sometimes by installing a third-party and occasionally possibly hazardous program.
Manufacturers including Samsung, OnePlus, and Xiaomi offers "Dual Messenger" functionality limited to a select group of chat apps. Some devices feature a secure mode or subdirectory where they can run distinct versions of any installed software, but users must authenticate each time they transition between apps. Finally, Android supports a separate "work profile," which is challenging to set up and utilize.
