dawudmeah, Jan 13, 2018 : Whenever I switch WiFi off or lose WiFi signal my mobile data does not turn on automatically. I have to instead reboot the phone everytime I leave the house in order to get mobile data back. This problem occured after the first oreo update a couple months back, which I thought would be fixed after the next update but unfortunately the problem is still there. I have tried rebooting the phone into recovery mode and wiping cache but this has not helped. A 4g or H+ symbol should appear next to the signal symbol of the first SIM(underlined) but as can be seen no such symbol appears. Any help regarding a fix to this problem would be greatly appreciated.
