[HOWTO] Phone not switching from 2G to higer - workaround

Some users have reported that the phone while passing through areas without cell reception or poor connectivity switches to other bands. The revert back to 3G or 4G does not happen later when back in good-reception areas.

-> A temporary fix is to enable flight mode and then disable it. This can be done from settings or notifications.
