Long time lurker. I luckily live in a fantastic LTE (even Wimax) area in East Harlem. Have perfect band 41 and can pull 50+Mbps.
Problem started once they flipped band 25 on a few weeks ago and I can't seem to hang onto the band 41 connection. At best I can stay connect for a few minutes before it falls back to band 25. I've tried every different priority mode in LTE engineering settings but to no avail. Is this likely a phone software problem or a tower issue? Any thoughts?
