iPhone...anything else work better?

Does anyone know if this system works better with anything other than the iPhone. Lots of problems with using Apple. May switch to an adroid product and Alexa. System slow to load if at all, volume changes, cameras don’t pick up motion. Has to be the phone.

The slow load times and cameras not picking up motion may be a result of poor WiFi and/or internet connectivity. I’m not sure what would be causing the volume changes though.

I’m using an older iPhone X running iOS 14.4 and the only real issue I’ve had is loading live view on rare occasions.
