My country UK is trying to stop the Covid19 virus using a smart phone app. The idea is to create many dead ends for the disease, it tells you when you were near someone that had tested positive for covid19 so you can test yourself before you have symptoms and self isolate early so you won't transmit the disease to another person. I hope it works. I think it uses Bluetooth to scan other people's unique app ID.
There is one test I would love to do but I have put it on ice because of the Pandemic. I would like to see what iphones do when you connect a Bluetooth input device to it. I have a bluetooth keyboard and touchpad, when I connect it to my android phone, my phone behaves like a desktop computer. A mouse pointer appears on the screen and the keyboard gets overridden by the Bluetooth one. This effect is the same with all android devices, phone, tablet, smart TV with android & bluetooth, android TV box with bluetooth, they all behave like a desktop pc when a bluetooth keyboard and mouse combo is connected to them. Would the same be true of an apple product?
I will wait until the Pandemic is gone to find out, we get no visitors at the moment so there is no way for me to try.
