The second space on your phone allows you to create a separate environment within the same device. You can keep personal and work data separate, improving privacy and security, helping in organizing different aspects of your life, like separating APPs for personal and professional use and providing the ability to customize the second space independently. Only a small amount of storage will be taken up when the second space is turned on.
Note:
1. The APPs, contacts, text messages, photos, files, etc. migrated to the second space will occupy storage space. For example, if you migrate a 1G file from the initial space to the second space, there will be two files in the initial space and the second space, occupying a total of 2G of storage;
2. When using the second space, just like the initial space, the cache generated by the application, the saved photos, and the saved files will occupy the mobile phone storage.
