I faced a similar problem. My android phone’s hotspot stopped working. And I think this is what caused it. I use my android phone to share internet with my PC via hotspot. And while the phone’s hotspot is on, I put it on charge, lest it would go off before I know.
I did this almost every day for about a year – my phone never rested; it was always on charge whiles the hotspot is on. Then I began to experience this problem of my phone’s hotspot not working. I think something got burnt or destroyed in it while it was always on charge every time it is on hotspot.
Perhaps, you are experiencing this because you have done something similar to what I did to my phone.
