Some users feedback that they have to switch networks before sharing photos on Facebook, and they feel it is inconvenient. Actually, most high end mobile phones like iPhone and most of Samsung mobile phone do not need to switch WiFi to share photos directly through Ftp or Facebook. The reason is because these models support MultiPath TCP (MPTCP) protocol, and will automatically switch to another network available in case one does not work.
Setting as follows: (It may use mobile bandwidth. Generally, to share a single image size will not exceed 1M bytes)
1.Find the IP address setting item in the wireless network setting of the mobile phone system;
2.Switch DHCP to static IP;
Set IP address to 192.168.9.xx（xx to 1~255）, the subnet mask to 255.255.255.0, leave the gateway and DNS blank
3.After re-launching App, you are no longer required to switch the network to share photos. And the next time you are using this CamFi, you do not need to set it again.
