There is a thread over on Reddit that saw Lumia 920 owners share horror stories after installing the new update, as it concerns the handset maintaining a connection to AT&T. It seems that one user has shared his grievances on seeing his device go through the full works where connection possibilities are concerned, starting from no service to LTE with full bars, EDGE and 4G, all in a single spot without moving anywhere. Definitely not a normal occurrence, we do hope to see Nokia fix this particular issue as soon as possible, and for those who have yet to install the latest firmware update, it makes perfect sense to hold it off at the moment.
