When I'm using my mobile data and go into blackspot and lose connectivity, e.g. a train tunnel, when I have reception again the data is not working properly.
In each instance the data is still on but I'm not able to receive messages through WhatsApp or use my browser. The issue is resolved by rebooting the phone, but obviously I shouldn't have to do this. Anybody experiencing this or know any solutions? Would a bug fix be needed? :/
