I have been having a very hard time trying to use another phone's hotspot. The phone being used as the hotspot is an LG Stylo 4 and there have been a few different phones connected with no problems in the past, however when I connect either of my S9s it is showing connected but then says "Internet may not be available" and gives the options to turn Mobile data on or switch networks. Nothing will load when connected to the hotspot. The Stylo is used frequently with other phones and my Galaxys are the only phones that wont work. I've tried everything I can think of with no luck, has anyone else had issues connecting to hotspots?
Have you tried resetting the network settings? Just a heads up, by resetting the network settings, it will remove all wi-fi and Bluetooth settings you currently have saved.
