In order to get my iPad to connect to my phone I have to take the phone out of my back pocket. I don’t have to unlock the phone or anything. Just take it out. If my phone is in my back pocket the iPad can’t detect the phone. Once the two are connected I can put the phone back into my bank pocket, and use the phone as a hotspot
I am more worried about breaking the phone when I sit down to ever keep my phone in my back pocket. The one time I did, it crushed the camera.
