I have this strange problem with my A55 - 4G and 5G disappears multiple times a day and only comes back if I restart the phone. Any ideas? SIM card works alright in other phone.
I have same problem om my new A56 5G, but I found today what is the problem (dont know how to solve yet). When you are out of wifi range and you loose mobile network there is some flag in system that marks "your offline" for apps. It doesnt change state when you reconnect to 5G or LTE. Phone shows 5g active, but apps claims that there is no intenret access. Reset of lte settings or going into flight mode is not helping. Only solutions is to either reset phone or connect to any wifi as this resets the flag. Do anyone knows how this works internally and maybe knows better way? Its very annoing when I travel with train and loose this connection multiple times when no wifi in range...
