Cannot open location in Emergency SOS SMS

I cannot answer that, nor comment on it, since I don't know. The support document does not indicate that the emergency contact needs to be an iOS user. You may be better served by contacting Apple Support direct to describe your issue, or if you have an Apple Store nearby, stop in there. Make sure the contact you are sending that to can handle MMS. For some reason, the image you provided does not show that an image was received by the other phone, but there is some type of link provided.

You can report anything you wish using the Feedback link. Feedback - iPhone - Apple If you can find something in the Emergency SOS documents that states that it only works with an iPhone, I would like to see it, since I cannot find it myself.

I've never used it before, but I believe it sends map info. It may be the Android devices cannot render that information. Do you have Location Services turned on for your device, and also in the Emergency Calls & SOS setting for Location Services?

If you go to Health app, then tap on Medical ID, there is some information there to help define that.

You may please check Settings > Privacy > Location Services > System Services [Check your location sharing settings here and enable where ever you would like to have them]

Again, what they see in Android, is based on their device. If it does not open a map location, that has to do with their maps, and their ability to receive MMS.

Again, I cannot be sure of that, and until you speak to Apple, neither can you. That would not make sense anyway, since that information is for emergency responders as well.
