Greetings thorium,
Thank you for providing us with a thorough description of the issue you are having along with the troubleshooting steps you have performed to try to resolve the issue.
Please check to see if there is any sort of VPN application or service that is running on the Android device. This may interfere with the Wi-Fi connection between the camera and the device. In case there is a VPN running, then let's disable or turn it off prior to connecting the Android device to the camera.
Some Android devices have a feature where the device will automatically disconnect from a Wi-Fi device if it detects that there is no internet connection since many users will use the device's Wi-Fi function to surf the web. Since the camera itself does not provide internet service to the Android device, the Android device may be disconnecting from the camera. Please check to see if this feature is enabled on the Android device and disable it prior to connecting the device to the camera. This usually applies when using the camera's access point mode.
