I have never seen that issue. The only time I might have seen was if the 4G LTE network was very weak. I don't remember having issues getting my computer and other devices to connect to the mobile hotspot on my phone. I have used the hotspot on at least five different smartphones but one of those models you mentioned.
Have you tried replacing the SIM card to see if that helps?
