Custom Homepage
The default Homepage is Library. You can set any of the other Function
pages as the Homepage. You can return to the Homepage by tapping the
homepage icon from the dropdown notification center.
Server Selection
The server is allocated according to the system language by default. The
Chinese language system uses the CN server （ Corresponding server:
send2boox.com ） , and the other language systems use US server
（Corresponding server: push.boox.com）;
After manually selecting the server, it will no longer be automatically
matched according to the system language;
Please try to choose the server in your area. This will avoid the slow
network connection which impacts the use of some specific functions
(including bookstore, synchronization, application market, OTA detection
and other functions that require networking);
