Q：The tablet I bought was supposed to have 15GB of RAM, but I only received 8GB.
A：1. The device is configured with 8GB of physical RAM, and the software includes memory expansion technology, which allows setting a maximum virtual memory of 7GB, thus achieving a RAM size of 15GB;
2. Setting path: Settings - Memory Expansion - Turn on the switch, select 7GB, and restart for the changes to take effect.
