It might be a good idea to go into the Accessibility settings and turn on the flash when the phone is ringing. That helps a lot of older people with hearing issues notice their phone is ringing; your mother may benefit from it as well.

I looked up videos of the features in action:

Android: https://youtu.be/3LEcJDP_T68?t=32

Apple: https://youtu.be/2HdcWzgp69s?t=40


Android's is a 3 second countdown before calling emergency sevices, Apple's is a 10 second.

I have no idea how people are going to cancel it in 3 seconds. Android's is a bad design here IMO.
