Network sharing keeps breaking the connection and reception is poor
I bought the phone for my son for it's battery specs and durability. He is sharing the connection at home for his computer (100mb unlimited 4G contract / SIM). The main issue is that the internet is breaking up all the time requiring reboot and reconnect. He had an old Huawei before which was able to do this network sharing without problems. Is this a known issue and can it be fixed with some software? Other issue is that compared to other devices, he seems to have a poor connection. He lives in a rural area in Finland but there is still good network coverage. This disrupts using IM / video call apps like signal or WhatsApp (problems especially with signal).
