iOS has had an issue for years now, where if you lock the screen of the iPhone that using the personal hotspot, it will automatically disconnect for some stupid reason. Android doesn’t have this problem. I think the reasoning is, because iOS and android used to different hotspots. Say I use my sisters, android devices are hotspot, and that never happens when I lock my device. Can Apple use the same Wi-Fi hotspot very because this is really annoying
I’ve not seen reports of this bug and I’ve never experienced it. I’ve run basically every beta since iOS 13, had every generation since the iPhone 7, and I have my own iPads plus all of my kid’s iPads across a couple of generations and I’ve never experienced it disconnecting when the screen becomes locked.
I’ve had it where they couldn’t see the network if I lock before they’ve connected, but once they’ve connected I’ve never seen disconnects just because the screen is locked.
I would be royally irritated if I did experience it though. Have you tried erasing everything and setting the phone up as new and hotspotting? Maybe there’s a small bug somewhere in your backup causing the issue that a restore carries over?
