Within the GUI; Unable to Change: Image Flip, WiFi SSID, WiFi Password

[MilkManzJourDaddy]

Title says all. On Fedora 30, and original sport version of Yiaomi Yi.

Also, just as in #19, certain ascii characters typed in the WiFi Password or SSID fields, navigate away from the settings/config' screen. HOWEVER even when using other characters, Image Flip for video recording, nor the WiFi Password, nor the SSID could be changed via the GUI. I have not had time to try and do so via a file, or cURL/JSON, et cetera, and some syntax snippets might help.
