It's always annoying when you can't connect to the camera's hotspot. You can try the following to connect to the camera's hotspot.

-Disable mobile data on the mobile phone. 

Newer mobile phones automatically switch back to the mobile data connection if you are connected via WiFi to the DIVM-550 and no internet is detected.

-In the latest Android update Android has made a requirement that you must have your location turned on in order to use the wifi, please turn your location on on your mobile.
