How to set device memory？

Device memory shows the memory running on the user's computer. Enter 8 means 8G memory, and its valid values are 2, 4, 8, 16, 32, and valid values.
In MuLogin, the range of device memory values is limited to the most commonly used 8, 16, 32. If the value obtained from the fingerprint database differs from these, it will be replaced by one of the commonly used values.
